Eric Black

Solutions Architect at Recovery Point Systems

The ability to leverage multi-tenancy along with immutability is a huge benefit for us

The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top. Veeam Backup specifically has started to streamline their API, and they are doing that with SOS API. They have optimized it. Any of the S3 devices out there that support this SOS API can have far more API calls at once. On our side, that translates to better restoration. With SOS API, it can leverage far more restorations at a single given time or read from the device in simple terms. That results in maximizing the output and throughput from the device itself.

A robust solution with good performance and support

This is a solution that scales well, although I think that we have stabilized in terms of use. With respect to scalability, we have an open question as to whether we will be able to grow into a cloud-based deployment. We don't know in what ways this solution will assist us with the migration, or whether we can still use it for DR. We don't know about the type of backup, be it full, incremental, or otherwise. We are also looking for a cost-savings if we migrate. These are things that we will find out over time. We have about two petabytes of data.

Yves Sandfort

Gives us a lot of advantages when we need to expand resources

Stability can be improved. Adding all these new features is nice, but we are now at the level where most of the features you need in production are there. The stability is not from a day-to-day operations perspective, but more from a supportability perspective, because currently some of the support scenarios require you to completely evacuate hosts or the complete cluster. That sometimes can be a stretch. This would clearly be an improvement if the support teams were given additional tools to make that easier. Upgradability could be a bit easier sometimes. We are now where vSAN can be updated without ESXi, but there is still enough dependency. So that would be good if that actually would be uncoupled even more. Dashboards are there, and we use vROps as well. So, we have all the beauty of capacity planning and everything over there. That's not really something where we need a lot of other things.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."

"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."

"The most valuable feature is Safe Mode."

"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."

"The most valuable features are the Metro clustering, and disaster recovery."

"Speed and ease of use are the two most valuable features."

"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

More Pure Storage FlashBlade pros

"The most valuable feature is the robustness, which is typical of IBM because their software generally just works."

"The ease of use is the solution's most valuable aspect. It's very user-friendly."

"Adding new nodes and expanding vSAN forward is simple and non-disruptive for a lot of our customers."

"The product’s ecosystem is better than Nutanix’s."

"It is easy to find information out there, not only from searching the web, but even the times I have engaged VMware support."

"The solution is easy to use."

"The installation is very easy."

"The most valuable features are its price point and that you can use existing storage; no specific storage requirements are needed."

"Storage policies are used to perform operations in the VMs. This feature allows you to create storage policies for VMs to get performance, high availability, I/O policies, etc."

"The solution is simple to use compared to other solutions, such as Hyperflex, VxRail, and Nutanix"

More VMware vSAN pros

Cons

"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."

"Pure Storage FlashBlade should improve on more cloud integration."

"I want efficiency. FlashBlade doesn't have efficiency now."

"The solution is expensive."

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."

"The features provided for SMB customers are limited."

"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

More Pure Storage FlashBlade cons

"The reporting mechanisms need improvement."

"he interface is not user-friendly so the ease of use could be improved."

"The solution could be improved by having more filtered and multiple view volumes instead of a single view."

"I am looking for more of a software-defined storage platform that uses different protocols, such as iSCSI, NFS, and CIS, and maybe also has an object as part of that. They should 100% make it more of a storage-based product where it is not linked just to VMware, and it also has NFS and iSCSI built-in at a scalable level. They should turn it more into a dedicated storage-as-a-service platform instead of just being built into the VMware kernel. Their level one and level two support is not at all good, and it should be improved."

"The biggest room for improvement I see in vSAN is the lack of SAN connectivity. I've kind of joked around that there is no "SAN" in vSAN. And it's something that we've worked to try and introduce some options for, and we're going to continue to work towards that."

"If one node out of your ten nodes fails, it takes a lot of time to replicate and rebalance VMware vSAN. This time can be reduced. When a node fails and the data is not accessible, vSAN has to be rebalanced to make the redundancy level of two again. However, if it is taking a lot of time and any other hardware fails during that time, then we have a problem. Two disk failures mean that all data will be lost, and we may have to recover it from the backup. So, the number of threads that run to do the rebalancing could be more so that the time taken to make it fully redundant again is not so much."

"We plan to switch products since the hardware nowadays is a little bit outdated and we need to scale up a bit."

"The monitoring feature in VMware vSAN could be better."

"It could have some automation. We haven't involved ourselves in a lot of automation around the vSAN environment capabilities. We're still running it using a very traditional setup. So, there could be some plugins to automate it using third-party environments, such as Jenkins."

"I see room for improvement with vSAN in particularly in the reporting realm. Now, with vSAN 6.7, they're starting to include vRealize Operations components in the vSphere Client, even if you're not a vRealize Operations customer. So, that's really good. It exposes some really low-level reporting. I would like to see more of that. However, you have to be a vRealize Operations customer to obtain that. I would like to see more include of this included in the vSAN licensing."

Pricing and Cost Advice

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

"I rate the tool's pricing a seven to eight out of ten."

"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."

"The price could be cheaper."

"Our customers have seen a reduction in TCO."

"I feel that the price could always be lowered."

"I understand that it is competitively priced compared to other brands."

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

More Pure Storage FlashBlade pricing and cost advice

"If you are cost-sensitive then this solution is not for you."

"For a database, on a yearly basis, we pay approximately $3,500 for licensing fees. The solution is sold as a subscription on a yearly basis so there are no other ancillary costs."

"VMware is not a cost effective solution, especially if you have a Microsoft shop. In this case, you would have to purchase the VMware license when there are already Hyper-V solutions that could do it for much cheaper."

"Perhaps a bundle, like Essentials, would allow more businesses to make the leap to the product."

"This is a cost-effective product. It's a bit cheaper than the other solutions."

"There is a license required for this solution, it is a one-time payment. However, if they want support for the solution, it can be paid annually or for three years."

"I would like to see this technology be made available to smaller businesses, who might benefit from high availability but struggle with the entry fee."

"The first 1-2 years of purchasing vSAN will be expensive. Thereafter, the longer you are running it, the more cost savings you will have."

"For a classical node plus storage solution, the price is higher."

"ROI from an administrative perspective is clearly much better because I only have to deal with one user interface."

Overview

FlashBlade is the industry’s most advanced scale-out storage for unstructured data, powered by a modern, massively parallel architecture to consolidate complex data silos (like backup appliances and data lakes) and accelerate tomorrow’s discoveries and insights.

Pure Storage

IBM Spectrum Accelerate is a software-defined block storage solution designed for rapid deployment across heterogeneous infrastructure for hybrid cloud and delivering consistent service levels to a dynamic workload mix. It is based on proven grid-architecture, enterprise-scale IBM XIV technology. IBM Spectrum Accelerate can be deployed, including as hyper-converged infrastructure, on any x86 server, on pre-installed third-party appliances or on public cloud infrastructure, and is available as a service on IBM Cloud infrastructure.

IBM

VMware vSAN is a software-defined storage product that is used in collaboration with VMware ESXi hypervisor and that provisions and manages storage based on policies, regardless of the underlying hardware. The solution enables you to prime your business for growth through its seamless evolution (it is integrated with vSphere and requires no new tools), its flexibility, and its multi-cloud capabilities. As an industry-leading software, VMware vSAN provides high levels of performance with minimal impact on CPU and memory.

VMware vSAN Features

VMware vSAN has many valuable key features. Some of the most useful ones include:

Storage policy-based management (SPBM): VMware vSAN supports storage policy-based management for automated management of storage profiles.

Software-defined data-at-rest encryption: With this VMware vSAN feature, you can prevent unauthorized access of data at rest.

Multiple nodes: VMware vSAN provides clusters that can include as few as 2 nodes or as many as 64 nodes.

High security and availability: VMware vSAN offers stretched clusters, allowing more than one virtualization host server to be used in the same setup, promoting higher security as well as availability.

Deduplication: VMware vSAN’s deduplication compresses data to ensure efficient storage management and security.

HCI mesh updates: VMware vSAN clusters can share storage capacity with non-HCI Sphere clusters and can adopt HCI without having to scale computing resources and storage or replace existing servers.

Simplified file services: With VMware vSAN’s file services, backup of file shares is simplified. You can use APIs that allow backup and recovery software vendors to integrate with your VMware vSAN file services, which enables backup software to track new data and add scalability enhancements to files.

VMware vSAN Benefits

There are many benefits to implementing VMware vSAN. Some of the biggest advantages the solution offers include:

Reduced total cost of ownership (TCO): VMware vSAN helps you reduce upfront costs for businesses because it can be easily deployed on inexpensive x86 servers. In addition, its highly scalable infrastructure and quick deployment also save organizations time and money, making it an efficient storage solution.

Good manageability: VMWare vSAN is easy to set up, manage, and provision, without sacrificing performance.

Scalability: VMware vSAN is agile and allows administrators to scale storage on demand, quickly, and efficiently via policies and rules.

Simplicity: VMWare vSAN is simple to configure since it is embedded in the vSphere hypervisor. Installing it using the vSphere Web Client can be done quickly.

Reduced risk: VMWare vSAN reduces the risk associated with digital transformations by utilizing existing tools, skill sets, and solutions.

Reviews from Real Users

Below are some reviews and helpful feedback written by PeerSpot users currently using the VMware vSAN solution.

PeerSpot user Yves S., CEO, Cloud Evangelist at Comdivision Consulting GmbH, says, “vSAN gives us a lot of advantages when we need to expand resources. We have an overall larger host infrastructure, and we split that up for specific customer test and use cases. In that specific scenario, we can easily add more hosts or reduce the number of hosts in the environment.”

A reviewer who works in Infrastructure Security explains, “The ease of use is great. The initial setup and upgrade process was pretty straightforward. And, technical support is great.”

Laurent N., Director at Softlogic, comments, "The feature that I have found most valuable is that it is easy to deploy. It is easy to create and delete virtual servers. It is easy to create the load balancing and the clustering."
