Featured Reviews

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.

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.

Anil Rahulwar

Storage Engineer at Movate

Offers good features like Fusion and stable product with better customer service

Fusion is the only best feature, but it's a very good feature. Nexenta is a very old product. Nexenta is a well-established product used in the UK, US, India, Dubai, Qatar, and other countries. It is very good. The interface is up to date. Everything is up to date. The OS version was recently upgraded to 5.5 FP3. AI features: DataDirect Networks owns Nexenta and has won awards for AI. They continuously work on AI features. DDN also has a product called Tintri Infinia with AI features. And NVIDIA product also has AI features. I look forward to working on those products.

Quotes from Members

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

Pros

"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."

"It's very easy-to-use."

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

"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."

"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."

"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."

"The initial setup is pretty quick."

"The most valuable feature of this solution is performance."

More Pure Storage FlashBlade pros

"The most valuable features are tiering to S3 and being able to turn it on and off, based on a schedule."

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

"NetApp's Integration with AWS has helped us because we had a tough time transferring data when we used an ONTAP competitor as our storage partner. They don't have integration with AWS tools, so we had to figure it out on our own. ONTAP has built-in integration and allows us to replicate a copy to our second data center."

"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."

"There is unified storage, which provides flexibility. It is set up perfectly for performance and provisioning. We are able to monitor everything using a separate application. It provides error and critical warnings that allow us to take immediate action through ONTAP. We are able to manage everything, log a case, and follow up with the support team, who can fix it. That is how it is unified."

"Another feature which gets a lot of attention in our environment is the File Services Solutions in the cloud, because it's a completely, fully-managed service. We don't have to take care of any updates, upgrades, or configurations."

"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."

"The solution’s Snapshot copies and thin clones in terms of operational recovery are good. Snapshot copies are pretty much the write-in time data backups. Obviously, critical data is snapshotted a lot more frequently, and even clients and end users find it easier to restore whatever they need if it's file-based, statical, etc."

More NetApp Cloud Volumes ONTAP pros

"It has a feature called Fusion that makes it more secure and productive."

Cons

"The speed could be improved."

"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."

"The documentational aspect of FlashBlade needs improvement."

"I would like to see more deduplication."

"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."

"I would like to see better integration."

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."

"I would like to see more monitoring capability included in the next release of this solution."

More Pure Storage FlashBlade cons

"There is room for improvement with the capacity. There's a very hard limit to how many disks you can have and how much space you can have. That is something they should work to fix, because it's limiting. Right now, the limit is about 360 terabytes or 36 disks."

"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."

"I rate the scalability a five out of ten."

"The support is good in general but the initial, front-line support could be improved. Because I have already been using the product for so long, when I call support I would rather talk to somebody who is a little bit more advanced or senior, rather than talking to the first-level support. Usually, it takes some time to reach out to their senior support."

"It definitely needs improvement with respect to clustering and with respect to more collaborative integrations with Azure. Right now, we have very limited functionalities with Azure, except for storage. If CVO could be integrated with Azure that would help. When there is any sort of maintenance happening in the cloud, it disrupts the service in Cloud Volumes ONTAP."

"Scale-up and scale-out could be improved. It would be interesting to have multiple HA pairs on one cluster, for example, or to increase the single instances more, from a performance perspective. It would be good to get more performance out of a single HA pair."

"The key feature, that we'd like to see in that is the ability to sync between regions within the AWS and Azure regions. We could use the cloud sync service, but we'd really like that native functionality within the cloud volume service."

"The cost needs improvement."

More NetApp Cloud Volumes ONTAP cons

"There were some SMB issues, but they were resolved."

Pricing and Cost Advice

"The product is very expensive."

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

"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."

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

"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."

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

"The price could be cheaper."

"We used a reseller for the purchase."

More Pure Storage FlashBlade pricing and cost advice

"Make sure you investigate what your requirements are going to cost you using the native cloud solutions versus what NetApp is going to cost you, to make sure you have a business case to go with NetApp."

"The solution's pricing is reasonable."

"For enterprise customers, it's a very cost effective. But in the SMB segment, yeah, pricing is a little bit challenge for your time."

"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."

"They give us a good price for CVO licenses. It is one of the reasons that we went with the product."

"They allow a special price if you are working closely with them. Since we have a lot of NetApp systems, we got some kind of discount. That's something they do for other customers, not just for us. The price was fair. In addition to the licensing fees, you're paying Amazon for your usage..."

"It is expensive. There are no costs in addition to their standard licensing fees."

"Our licensing is based on a yearly subscription. That is an additional cost, but because of the storage efficiencies that the NetApp gives, even with the additional cost of the NetApp license, you still end up saving money versus straight Azure native for storage. It's definitely worth it."
