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.

Deliver improved performance in data processing and foster extensive AI initiatives

I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system. It achieved the best results when integrated with IBM hardware. Even though it is complex, it provided significant performance advantages in large-scale data management. Its fault tolerance mechanisms and integration capabilities make it popular for extensive AI initiatives and data processing tasks for organizations like Daimler Benz and Bosch.

Allows customers to manage SAN and NAS data within a single storage solution

The tool's most valuable features are the SnapLock and SnapMirror features. If something goes wrong with the data, we can restore it. This isn't a mirror; we store data in different locations. If there's an issue on the primary site, we can retrieve data from the secondary site. Multiprotocol support in NetApp Cloud Volumes ONTAP is beneficial because it allows customers to manage SAN and NAS data within a single storage solution. This feature eliminates the need to purchase different types of storage.

Quotes from Members

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

Pros

"What I like best about Pure Storage FlashBlade is its object storage functionality, plus it has fast underlying hardware. Pure Storage FlashBlade is also very stable. I find its stability one of its valuable features."

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

"The initial setup is pretty easy and simple."

"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."

"It uses the same platform for connectivity so integration is seamless."

"It is very easy to use, and it is very fast."

"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."

"I would rate Pure Storage FlashBlade a ten out of ten."

More Pure Storage FlashBlade pros

"We can have multiple systems within the same file system."

"Technical support has been very helpful. They provide us with pretty good solutions that we can implement moving forward."

"It has been pretty reliable throughout the years. As far as capacity is concerned, it can handle most heavy loads."

"We use GPFS Scale for parallel file access, the file management, and it's an essential part of our operations."

"It is incredibly scalable and stable."

"We are using it for monitoring all of our storage."

"I rate this product ten out of ten."

"It makes our file system sharing a lot easier, even across different continents. We have had file systems shared across different continents with no performance degradation."

More IBM Spectrum Scale pros

"The feature which I like the most is that it has the capabilities that the traditional storage system offers. It provides all the functionality. The deduplication and compression work exactly like ONTAP's traditional storage. So people who have experience with that find it very easy to manage."

"SnapMirror helps mirror metadata and data volumes between endpoints in a data fabric."

"We're able to use the SnapMirror function and SnapMirror data from our on-prem environment into Azure. That is super-helpful. SnapMirror allows you to take data that exists on one NetApp, on a physical NetApp storage platform, and copy it over to another NetApp storage platform. It's a solid, proven technology, so we don't worry about whether data is getting lost or corrupted during the SnapMirror."

"NetApp's Cloud Manager automation capabilities are very good because it's REST-API-driven, so we can completely automate everything. It has a good overview if you want to just have a look into your environment as well."

"The most valuable features are that it's reliable, simple, and performs well."

"ONTAP has been very stable for us, specifically in the cloud environment. It allows us to have high availability as well as standalone systems if that's what we want within our specific workloads. Also, on-premise has been a very stable environment. We have very few outages and when we do, we work with support to get systems back online in a timely manner."

"If anything happens, their technical support will come onsite and fix it."

"This solution has made everything easier to do."

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."

"There could be improvements in public cloud integration."

"I have not seen ROI."

"I would also like to see better support for CIFS workloads."

"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."

"It's on the expensive side, as expected for a niche product."

"The solution is expensive."

"Its configuration should be easier."

More Pure Storage FlashBlade cons

"We do have some issues where Spectrum Scale does not work as expected. We have seen our Spectrum Scale servers go down unexpectedly, but because we have a cluster, it does not take out the entire organization."

"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."

"The biggest problem is that it is not able to provide block storage."

"There can be improvements in fault tolerance and making erasure coding faster."

"Maybe it needs integration with HA."

"The main issue that we have now is with the encryption. They want to use more metrics in encryption, which is not working very well."

"The solution's pricing could be better."

"The initial setup is complex, especially if trying to avoid erasure coding, as it requires more discs. Avoiding erasure coding can significantly increase costs."

More IBM Spectrum Scale cons

"We have customers that are still using IBM mainframes and that very old SNA architecture from IBM. There are questions about how you interconnect the data on the mainframe side... But I don't know if it's worth it for NetApp to invest in developing products to include mainframes for a few customers."

"If they could include clustering together multiple physical Cloud Volumes ONTAP devices as an option, that could be helpful."

"I would like to see something from NetApp about backups. I know that NetApp offers some backup for Office 365, but I would like to see something from NetApp for more backup solutions."

"The DR has room for improvement. For example, we now have NetApp in Western Europe and we would like to back up the information to another region. It's impossible. We need to bring up an additional NetApp in that other region and create a Cloud Manager automation to copy the data... I would prefer it to be a more integrated solution like it was in the NetApp solution about a year ago. I would like to see something like AltaVault but in the cloud."

"When it comes to a critical or a read-write-intensive application, it doesn't provide the performance that some applications require, especially for SAP. The SAP HANA database has a write-latency of less than 2 milliseconds and the CVO solution does not fit there. It could be used for other databases, where the requirements are not so demanding, especially when it comes to write-latency."

"We would like to have support for high availability in multi-regions."

"NetApp's support could improve"

"How it handles erasure coding. I feel it the improvement should be there. Basically, it should be seamless. You don't want to have an underlying hardware issue or something, then suddenly there's no reads or writes. Luckily, it's at a replication site, so our main production site is still working and writing to it. But, the replication site has stopped right now while we try to bring that node back. Since we implemented in bare-metal, not in appliance, we had to go back to the original vendor. They didn't send it in time, and we had a hardware memory issue. Then, we had a hard disk issue, which brought the node down physically."

Pricing and Cost Advice

"Our licensing is renewed annually."

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

"The price could be cheaper."

"Licensing fees are paid yearly."

"Our customers have seen a reduction in TCO."

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

"The price of this solution could be made more affordable."

More Pure Storage FlashBlade pricing and cost advice

"The licensing is based on the number of terabytes."

"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."

"The solution is costly but reliable."

"The pricing of this solution is definitely higher than what the typical Azure Files and AWS solutions charge, but given the features and the stability NetApp has provided, we are okay with it. We are not complaining about the pricing."

"In addition to the standard licensing fees, there are fees for Azure, the VMs themselves and for data transfer."

"Cloud is cloud. It's still expensive. Any good solution comes with a price tag. That's where we are looking to see how well we can manage our data in the cloud by trying to optimize the costs."

"I know the licensing is a bit on the high-end. That's when we had to downsize our MetroCluster disks and just migrate to disks that were half used. We migrated into those just to reduce maintenance costs."

"Our licensing costs are folded into the hardware purchases and I have never differentiated between the two."

"For NetApp it's about $20,000 for a single node and $30,000 for the HA."

"Cost is a big factor, because a lot of companies can't afford enterprise grade equipment all the time. They skimp where they can. I would recommend that they improve the cost."

"Once we deploy the pay as you go model, we cannot convert this product as a BYOL model. This is a concern that we have."

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 Scale is a cluster file system that provides concurrent access to a single file system or set of file systems from multiple nodes. The nodes can be SAN attached, network attached, a mixture of SAN attached and network attached, or in a shared nothing cluster configuration. This enables access to this common set of data to support a scale-out solution or to provide a high availability platform. IBM Spectrum Scale has many features beyond common data access including data replication, policy based storage management, and multi-site operations. You can create a cluster of AIX nodes, Linux nodes, Windows server nodes, or a mix of all three. IBM Spectrum Scale can run on virtualized instances providing common data access in environments, leverage logical partitioning, or other hypervisors. Multiple IBM Spectrum Scale clusters can share data within a location or across wide area network (WAN) connections.
