DataCore SANsymphony Reviews

Usually, our clients want to replace some storage units from NetApp. Sometimes it works, and sometimes it doesn't because NetApp still has some features that DataCore SANsymphony would like to have.

DataCore SANsymphony's stability is okay.

DataCore SANsymphony should integrate file servers at a good price into the solution. The licensing is expensive, and you cannot manage a big file server with DataCore SANsymphony without paying a lot of money. NetApp is easier to sell, and we have had projects where NetApp was a lot cheaper than DataCore.

Our customers want their block storage to be fast, redundant, and highly available. You also might have a large fire storage for data that the customer does not need to access urgently. When you want to enclose this in the DataCore architecture, you have to pay the full amount of money as with block storage, which can be very expensive. Sometimes, it is very expensive to use DataCore SANsymphony.

I have been using DataCore SANsymphony for about one year.

I didn't notice any problems with the solution's stability. DataCore SANsymphony's stability is okay.

The first installation of DataCore SANsymphony took a long time. I am not sure if that was due to a lack of experience or software issues, as I was part of the sales team. I am not mounting DataCore SANsymphony. I am just selling the solution to the customers.

I rate DataCore SANsymphony a seven out of ten for stability.

You can scale DataCore SANsymphony as much as you want if you are willing to pay the price. The solution’s scalability is high and theoretically has no limit.

We won three or four projects last year but also lost some. In some cases, the decision was to go back to maintaining NetApp. Our clients are enterprise businesses.

I rate DataCore SANsymphony a six out of ten for scalability.

I have to contact the sales team and system engineers. I'm quite content with DataCore SANsymphony's system engineers.

Positive

I am not completely satisfied with the initial setup. I rate DataCore SANsymphony a five out of ten for its initial setup.

DataCore SANsymphony’s deployment takes around eight weeks.

DataCore SANsymphony's pricing is very high and should be much cheaper. You buy a license of DataCore SANsymphony, and then you have to add three or four times the price in hardware.

You have several SLAs. You have to buy the hardware equipment because DataCore SANsymphony doesn't run independently but on server hardware.

On a scale of one to ten, where one is cheap and ten is expensive, I rate DataCore SANsymphony's pricing a seven or eight out of ten.

We sell DataCore with the package that permits to use the latest version. We wouldn’t install another version.

NetApp is very good compared to DataCore SANsymphony in terms of flexibility and licensing.

I don’t know. I would ask them to compare.

DataCore SANsymphony is a good product, but there's room for improvement.

Overall, I rate DataCore SANsymphony a seven out of ten.

The solution is used for the provision of high performance and high availability block storage. By using auto-tiering, many applications can benefit from the high performance of current NVMe SSDs. At the same time, cold data is kept on low-cost storage resources.

The separation of data streams from different applications (e.g. SAP HANA, SQL server, virtualisation) also increases overall performance and availability.

The use of snapshots for data backup is already planned and scheduled. For this purpose, Veeam Backup 11 will be connected to SSY. The backup will then be LANless via Fibre Channel.

Among other things, we used SSY to bring a Splunk installation onto the existing central DataCore storage. Continuous data transfer rates of up to 2.6 GByte/s (16GB Fibre Channel, dual fabric synchronously mirrored systems over 20km) were also achieved.

The project was also much cheaper and easier to implement than any comparable solution.

The services already running (databases, virtualization) are not affected and run with the same performance as before the expansion.

Veeam is now configured to use storage snapshots. This reduces VMware snapshots to a minimum. The backup runs via Fibre Channel and relieves the LAN.

Synchronous mirroring was a prerequisite for the project. Two data centers are used, which are connected via two different WAN routes. 16G FC is used via the WAN. The "Systems managed Mirroring" feature was used for this.

Another feature that makes high performance possible is "pool striping", where accesses are distributed over a larger number of external data volumes (LUNs). The limiting factor for performance here is the external storage that is connected to the DataCore servers.

Snapshots are also an important feature. In connection with external applications, these enable an improvement in data protection.

CDP is an important feature for avoiding data loss in the event of ransomware attacks. You need more storage capacity, however, you get the possibility to return at any time and use the data saved up to that point. The recovery is much faster than with a classic restore.

With dedupe and compression, we can now save considerable capacity. An expansion of the capacity and thus the purchase of new licenses are thus avoided.

For an upcoming release, I would like to see a function that can manage the storage of multiple Datacore servers in a kind of "erasure coding". This would simplify scaling and make SSY more competitive with other providers.

NVMeoF should be implemented. This protocol will play a major role in storage infrastructure in the future.

Network protocols are becoming increasingly important. For future projects, protocols such as RoCE should be implemented. Especially in LAN infrastructures from 25G, a simpler and high-performance SAN infrastructure could be built here. The costs should be lower compared to Fibre Channel.

Improving support will be very difficult as it is already one of the best in the IT world.

I have been implementing SSY very successfully with many clients since 2008.

The system runs very stable. Through the use of server pairs, there is no more downtime. The storage service is always available, even if maintenance has to be carried out or a hardware defect has to be repaired.

The performance can be scaled very easily by adding data devices of the desired performance class.

It is also very easy to expand the capacity. By adding low-cost storage, cold data can be stored there. This also ensures that the hot data can be accessed with high performance.

Datacore offers one of, if not the best, technical support teams in the industry. Every request is handled very competently and in a short time.

The SEs are also very well trained and competent. They are always available for questions and are also very willing to give suggestions and information.

Positive

We previously used Netapp Metro Cluster. We switched due to the costs for the infrastructure (Metro Cluster) were too high. The performance was also no longer sufficient. The solution was too inflexible.

The implementation is somewhat more complex than with simple storage. In addition to the actual storage resources and the SAN infrastructure, the x86 server with Windows Server and SSY must also be installed.

The configuration of the storage is easy, as it is best to create many identical volumes and present them to the Datacore server.

These volumes are then included in the pool within SSY and centrally managed there.

The SAN configuration includes the construction of a FrontEnd, BackEnd, and Mirror layer. It is a little more complex, but not complicated.

The host systems access the resources via SSY, so these must also be configured in SSY. On the other hand, only the SSY servers need to be set up on the storage.

Being a DCIE myself, I did the installation.

Since the environment is dynamic (for example, changes, extensions), the ROI is not easy to determine. However, the TCO is more favorable than with other solutions.

Good planning is always very important. SSY is very flexible and can cover very different requirements. Therefore, it is important to keep a close eye on the requirements. If you have questions before implementation, ask support or a partner.

Also, pay attention to licensing. It may be cheaper to license a few TB more if you can make a jump in the discount scale.

Also note: Using DAS (internal storage) can be very cost-effective compared to external storage.

We considered different solutions such as Netapp FAS-Series, HP MSA, and 3Par.

I am glad to have used SSY. The solution is very stable and performs well. It requires very little effort.

What you do have to do, however, is regularly apply Windows patches. To do this, the node has to be restarted. You should therefore always use a pair with synchronous mirrors to avoid downtime.

I am an infrastructure engineer for a partner and 95% of the infrastructure that I recommend and/or install and maintain for my clients are based on the triptych: SANsymphony/vSphere/Veeam.

I have often succeeded in convincing clients to add security to their storage by replacing an old single-site infrastructure while providing a Business Continuity Plan solution.

Of all the customers where I installed the DataCore solution, only one decided not to keep it; however, it was for reasons of political strategy following a change of CIO.

The main feedback from my customers concerns the performance of the DataCore SANsymphony - thanks to the embedded Auto-tiering technology which avoids users purchasing an expensive physical storage when the majority of their data is no longer active beyond a few weeks and do not need to be stored.

They have a quality support team, which offers assistance in French when necessary (particularly for Public Service customers who do not speak English fluently). They respond very quickly to engage with any serious problems encountered.

Auto-tiering to obtain performance at a lower cost without the customer having to purchase ultra-fast storage is great. The ease of increasing the volume of storage without interruption of services and without impact on users is helpful. At the same time, they are leaving the choice to adapt storage technology according to a user’s needs. The abstraction of the hardware layer, especially when it is necessary to change the brand and/or model of equipment during infrastructure renewal is good. The possibility of installing the solution in HCI mode for small structures makes it possible to address large accounts as well as small businesses.

I would like to see SMPA (Shared Multi-Port Array) technology developed with the aim of allowing a configuration identical to other storage arrays: instead of having a single storage controller per site, competing arrays all have 2 controllers for redundancy and securing data access (3Par, Unity, MSA, etc.) It would be necessary to automate the operation of two nodes managing the same storage per site and no longer be obliged to manage it by a system of scripts which must be revalidated each time the product is updated.

I've used the solution since 2002.

There will always be problems with a software solution; the responsiveness of the support and developers allows them to be corrected very quickly, and even sometimes individually, in relation to a specific problem for a particular client.

In the majority of cases, the failures that I encountered with my clients had their origin in one of the other components of the infrastructure (hypervisors or switches).

Scalability is one of the many advantages, as the evolution of the solution is simple and does not interrupt services.

Of all the software that I use in my job, it is the one that has the best support. When the problem is not with DataCore, they often help me and sometimes even directly provide the solution to modify the settings on the other components of the infrastructure causing the problem.

Positive

Sometimes some customers use other storage solutions, but whenever possible; I advise them to switch to DataCore

The initial training and accompanying certification made it simple and practical to implement the solution.

I am not able to answer for my clients; however, as long as they do not move to another solution, their ROI should correspond to their expectations.

Most of the time, it is easy to prove that in the long term, this solution is the most advantageous for the client cost-wise; both in terms of equipment renewal and ease of handling.

When I started proposing and installing, I only knew about traditional infrastructures that did not provide security at the data level.

My professional career will end soon; however, as long as the product is available, I will continue to recommend it to more and more new customers and maintain it among those who continue to use it.

The most useful feature of SANsymphony is that it's able to manage any brand of block storage.

If it could integrate to a cloud gateway, then we could carry it directly to storage, instead of having middleware in between the storage and the cloud.

It's a very expensive solution, and the licensing costs should be lower.

I've been dealing with this solution for seven to eight months.

It's very stable, but you must know what you are doing because you need to have sufficient memory processing in order for SANsymphony to work properly. Once you have that down, it's actually quite easy to manage.

Scalability is easier because everything comes in pairs. Everything you need to do, you have to do in pairs. For DataCore SANsymphony, you don't need a witness node. You can actually run in pairs, and you can upgrade in pairs. You can find support for up to 64 nodes, if I'm not mistaken. It depends on how you want to design your architecture.

Based on my experience, their technical support is very good.

The initial setup is very straightforward.

One person can easily manage the entire software. There is a learning curve, and you need to understand the features, how it works, how to create your storage pool, and how to tier your storage pool. Once you understand those things, everything is actually quite easy and streamlined. You just need to know the basic architecture.

We have licensing costs on a yearly basis. They charge per terabyte, so in terms of cost, it can be very costly.

They have three different features, and you have to pay extra for those.

If you have multiple block storage, as in a silo, then you can use SANsymphony to manage the storage from one management portal. You can also tier the data from storage, say, for example, from HP storage to Dell storage, transparently. You can also do storage migration without any downtime.

Compared to VMware vSAN on Nutanix or VxRail, you need a minimum of three nodes, two nodes and one witness. However, for DataCore SANsymphony you don't need a witness node.

DataCore SANsymphony is very good and very solid. In fact, it's almost 20 years old, but the pricing can be an issue.

SANSymphony is used to provide HA storage block services to the vSphere Streched Cluster. The backend virtualized storage is a mix of internal node storage and SAN (Dell Compellent, IBM Storwize). It can be fiberchannel connected or iscsi or both.

By using this solution we provide a High Availability storage solution.

We can do the running of VMs in classic Windows or Linux workload and Citrix virtual Apps.

This is a software solution, so new functionality does not rely on any hardware.

SANSymphony allows us to separate the storage software from the hardware. That way, we can replace or add any backend in the cluster without downtime.

This ease of adding or removing storage allows us to control costs.

All maintening operations can be done without downtime as well. The team is happy due to the fact that they can do the operational tasks during day without impact on the production.

It helps us control storage costs.

This solution is very flexible. We can have 2 physical DataCore nodes with backend storage virtualized or we can have internal disks on the main site and hyper-converged 2 nodes on Robo sites. All this is managed from the same console and with the same functionnalities.

Continuous data protection (CDP), can be used to "protect" again ransomware by recording all write on disk in a log. You can recover your data with incredible time granularity.

The parallel I/O function is very useful to have good storage performance.

The ability to do asynchronous replication to a third site is a easy way to create a disaster recovery plan. 

Veeam Backup integration is a good new option. Now we can leverage a Datacore storage snapshot to do our backup without VM by using vsphere snapshot.

Datacore is developing a new WebUI with new dashboards. It is a good idea as the classic GUI is lacking dashboards. 

We need a better view to analyze the auto-tiering feature (like in DIS) to easier decide what type of storage we need to add. The current view in the GUI is too simple and we cannot see clearly cold data or hot data.

You can report all you want. There are a lot of counters usable in the console. However, there are too many. They need to create some pre-defined graphs or reports.

We have been using this solution since 2016.

It is a very robust solution. I have never experienced to total crash. I would like it if it continues this way.

Due to the design, the product has unlimited scalability.

The support team is really good. The product is frequently updated.

We previously used IBM Hyerswap and SVC. We had to switch due to the Vendor lock-in and poor flexibility.

The design is the more complex part due to all use case you can address with the product. That said, the setup is simpler if you are a SAN Storage admin.

We did look at vSphere vSan.

We use this solution for providing software-defined storage that is virtualized, in a true HA configuration. It provides SAN storage services to VMware vCenter hosts and VMware Horizon hosts, as well as some physical Windows and Linux servers. This platform allows us to leverage any storage that Windows can leverage, including other vendor SAN devices.  This allows us to keep existing storage, mirror SANs from 2 different vendors and even allow very easy migration from one vendor to another.  Most of our locations just use RAID attached storage (as it is the least expensive) with enterprise-class drives (both HDD and SSD).

This solution allows the use of off-the-shelf hardware and charges by the TB of storage. So, we can throw in our own enterprise-class hardware (including SSDs) and not pay any extra based on the type of storage we use. This is the same model used with server virtualization.

This has allowed us to keep the hardware separate from software. It is true "storage virtualization" at its finest. It has all the features of any high-end SAN such as fiber channel, iSCSI, thin provisioning, storage tiering, snapshots, continuous data protection/recovery, synchronous and asynchronous mirroring, performance reporting/graphing, and true HA design.

DataCore recently added a hardware appliance for customers who what a turnkey, easy to install solution.  So if engineering the underlying-storage is not your cup of tea, their appliance, which is built on top of Dell server/storage hardware, is the way to go.

No more vendor lock-in, overpriced drives, or forklift upgrades. With DataCore SANsymphony, you can utilize just about any storage you wish with this product such as another SAN, NAS, JBOD, FusionIO, etc. If Windows can see it as a non-removable drive, you can use it with SANsymphony. Also, you can use this to mirror any of these various types of storage, which is awesome for migration. Say, for example, you have an HP SAN and you want to migrate off it to your own JBOD-type storage, or you have two sites with two different storage SANs that you want to replicate data between. With DataCore, it is possible to mix and match just about any storage platform you want to use.

As software-defined storage, the system is designed to run on top of Windows Server OS (which can be virtual or physical) and can utilize the server's RAM to provide disk cache. This makes our 7.2K HDDs class storage run really fast, allowing us to use a bottom-tier class of drive and get the performance of a much higher class of drive. Also, if we have to add capacity or replace drives then we can just order replacement drives off the web, saving us quite a bit of money. Of course, we still use "enterprise-class" drives but we don't pay through the nose to buy hardware. If we want to upgrade the Ethernet ports from 1Gb to 10Gb then we just do it. The same goes for FC. If we want to upgrade from 4Gb FC to 16Gb, we don't have to do a forklift upgrade. We just buy the HBAs and we're off the to races.

The other great thing is DataCore keeps their product on VMware's approved HCL. So even if you have a SAN (backend storage) that falls off the HCL with VMware, because it's virtualized storage behind DataCore, you're covered. If you put the storage behind DataCore then you won't have to worry about VMware's HCL any longer. Because of this fundamental practice, DataCore was one of the first storage vendors to support VVOLs.

The ability to pool the storage to leverage thin-provisioning is a huge saving in space and costs.

There's very little that I can find in their software that I would say needs to be improved. Sometimes the updates are too frequent, where just as we finish updating all of our sites, another update comes out.

The de-dup console is not yet integrated inside the main SANsymphony console. They are working on it but it's not there yet.

While their console allows you to connect to each of the nodes without closing the interface, you have to log out and back in when you switch between different storage server groups. It would be nice if they had an interface more like vCenter, where you see all of the server groups in a list and can just click on each group. It would be nice to be able to see multiple groups at the same time.

Having more of an Enterprise approach (v/s a local storage cluster) view would provide better management of the environment. For example, their current reports can only be run for each storage server group. There is currently not a way to run the same reports or look at performance across the enterprise (only the local site).

Having an enterprise "Storage Dashboard" that can show capacity, usage, performance, and any issues would be very beneficial. Currently, DataCore does not have this. They recently added a web-based dashboard called DataCore Insight Services (DIS) to their product. However, you will need to be on their subscription-based model v/s their traditional yearly maintenance-based model. Also, the current DIS product does not span multiple storage groups and is in its infancy and is still very rudimentary in nature.  However, knowing DataCore's track record for fast, innovative development, I know it won't be long before they get it right.

We have been using this solution since 2008 (over 12 years).

The software over the years has matured to be very robust and allows you to build a very high-performing storage platform.

This product in unlimited in scalability.

DataCore Support is OUTSTANDING and they release new updates and features frequently (sometimes almost too frequently).  Their support department is a well-oiled machine and is the gold standard for how all vendors should be. Their online ticketing system allows us to not just see individual cases but for anyone in our enterprise/storage team.

Yes - We had a mix of various, black-box, type SANs (Dell, HP, Lefthand, DottHill, and EMC to name a few).  We switched to standardize the storage across the enterprise, maintain VMware supported storage, reduce costs, and add flexibility.

If you're an experienced SAN administrator you'll have no problems understanding their setup.  It is very straight forward.  The design of what you can do, because it's so flexible, is the most complex part.  You have LOTS of options. 

In-House

Within the first year, the product has paid for itself.

I would recommend sending administrators through DataCore's DCIE training/certification.  DataCore has many options from hyper-converged solution, to even providing their own storage appliances if that's what you are looking for. 

Yes - Dell, EMC, and HP.

While they support de-dup, it is recommended that you not de-dup the storage used for operating systems or high-change rated type data. The requires some planning to ensure the storage that is targeted for de-dup only have data that end users would be using (such as MS Office files, etc.)

• We use DataCore SANsymphony as our primary storage solution replicated on two hosts since October 2012. In July 2018, we dispatched them to the two server rooms.
• Each DataCore node consists of a server and two storage bays connected in SAS.
• We use this SAN to store our VMware datastore (300 virtual machines) for our 10 ESXi servers.
• Each server is connected to storage via two fiber channel links 8Gbps.

Previously, we had some Windows and Linux servers with direct-attached storage. Our server's farm increases faster than our server room. So, we thought about virtualizing our applications. We chose to use VMware ESXi and DataCore SANsymphony to create our new infrastructure and then began to deploy our infrastructure on one server room. Then in 2018, we chose to dispatch them for more security in two server rooms.

• The better features are the synchronous replication and the management console.
• The synchronous replication gives us the ability to make business continuity planning.
• I like the management console which is very easy to use.

DataCore is currently working with Veeam software for a better integration; this is my only desired missing feature today.

With this feature, Veeam do a snapshot on Virtual Machine, then snapshot the storage.
When storage snapshot is done, Veeam remove the Virtual Machine snapshot to avoid long period snapshot.
With a VMware snapshot period smaller, consolidate will be faster and production will be less impacted.
Then Veeam save VMs directly from storage snapshot without VM performance impact.

When Backup Job is done, veeam ask to Datacore to remove Storage snapshot without any VM interruption or impact performance.

We work with the enterprise edition, SANsymphony V SDS.

The solution is geared towards small and medium-sized businesses, with two or three node clusters supporting business continuity and nonstop operations of virtual machines or servers. This makes the solution very stable, cost effective and simple to administer and maintain. 

The solution's most valuable feature is its versatility, with there being support for all new hardware technologies and platforms, disc mirroring and very effective auto tiering. This translates into very advanced storage features, accompanied by a cost effective application or license.

The so-called hyperconverged infrastructure edition, sometimes knows as vSan, should be addressed. It is one component of the solution. Yet, DataCore is less competitive than certain other manufacturers, such as EMC, Cisco, and VMware vSan. It is competitive when it comes to a general purpose software defined storage solution. As such, a hyperconverged infrastructure solution could be improved.   

The solution could be better packaged and marketed. 

When it comes to a simple 2 node cluster business continuity solution for SMB companies, the downtime can be expensive.

We have been working with DataCore SANsymphony SDS for eight or nine years, although we are talking about a relatively new edition which was published several years ago, possessing similar technology. 

We have worked with the solution over the course of the past 12 months. 

DataCore SANsymphony SDSOne should not hurry with Microsoft patching and should try to use newer, stable versions of DataCore and Microsoft Windows server.

These are the perquisites. When fulfilled, DataCore works really well and is stable.

The stability is high and extremely good. Once set up properly, the stability really works. 

The scalability is excellent. 

We provide support. As such, we usually help to resolve issues arising with vendor DataCore.

DataCore's technical support is very good and I rate it as a nine out of ten. 

The installation is nice and straightforward. 

The length of deployment varies with the complexity of the customer's environment and can last from three to five days, including the planning and optimization.

Generally speaking, we do installation.

There are usually two people involved in the deployment and the main channels of the solution, one of whom is experienced with the Microsoft infrastructure and server, the set up and the configuration. The other person has experience in networking and the configuration of the network, interconnecting the nodes. So, there are not a lot of people involved. 

The solution is cost effective. 

When it comes to a simple 2 node cluster business continuity solution for SMB companies, the downtime can be expensive.

The solution has very advanced storage features, accompanied by a cost effective application or license.

We are a reseller.

There is DataCore and we are Datatek. We are just talking about similar names, Datatek being a DataCore reseller.

I rate DataCore SANsymphony SDS as a nine out of ten.
