Featured Reviews

Eric Black - PeerSpot reviewer
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.

Enhancing storage management efficiency with user-friendly experience
Our customers are using Zadara for their research and development environments. We provide infrastructure for government projects, but we are often not fully aware of their specific usage.  I typically use it for our infrastructure and offer both Zadara and Microsoft Azure to our customers Zadara…

Quotes from Members

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

Pros

"It's very easy-to-use."
"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."
"FlashBlade offers low latency, high throughput, and seamless scalability."
"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."
"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."
"The most valuable features are the Metro clustering, and disaster recovery."
"The most valuable feature is Safe Mode."
"It uses the same platform for connectivity so integration is seamless."
"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."
"Being able to scale on demand, and being able to get out of our security operation center, and not having to purchase hardware upfront, has drastically reduced the overhead that was required to maintain our information. We have also gained additional capabilities in terms of speed of replicating that information."
"The most valuable feature of Zadara is its ease of use and safety. Overall the solution is a complete package, it has all the features needed."
"The most valuable feature is the flexibility in terms of deployment options."
"The processing is much faster with this product."
"Zadara is a fully-fledged platform, and our customers are happy with its use."
"One of the most useful features is that they provide iSCSI as a service."
"Zadara saves both time and money."
"The most valuable features of Zadara are its visibility and simplicity to use."
 

Cons

"Its configuration should be easier."
"I would also like to see better support for CIFS workloads."
"I would like to see more deduplication."
"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."
"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."
"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."
"Commvault has mainly driven the Analytics, providing data and reports. However, the product has room for improvement, especially regarding storage analytics. Upgrading firmware has caused issues, requiring feature disabling to revert to traditional backups. The firmware upgrades sometimes affect Commvault backups."
"There could be improvements in public cloud integration."
"The reporting mechanisms need improvement."
"he interface is not user-friendly so the ease of use could be improved."
"Having iSCSI over the internet using a VPN, the IPSec tunnel is really the only thing that I find missing from this product."
"The initial setup of the solution is complex."
"The management interface is more geared towards end-users rather than a service partner like ourselves, and there are improvements that can be made around that."
"Currently, when we do firmware upgrades, it sometimes causes issues and is not as nondisruptive as desired."
"There are still some storage features that they lack. For example, other vendors implemented the auto-tiering feature a long time ago, while Zadara Storage Cloud is just coming out with this feature today. So, they are a little bit late compared to the market."
"The cost is not favorable as Zadara does not provide competitive rates for regions like South Africa and Ethiopia."
"There is room for improvement in pricing as it is currently quite expensive."
"The initial installation was difficult because many steps required the command line interface (CLI). Maintenance can also be complicated, especially when deeper troubleshooting requires navigating the CLI and searching for logs."
 

Pricing and Cost Advice

"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 is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."
"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."
"We used a reseller for the purchase."
"The price of this solution could be made more affordable."
"The price is a little high."
"Our customers have seen a reduction in TCO."
"I feel that the price could always be lowered."
"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."
"The pricing is very competitive and the fact that they have very compelling discounts for multi-year commitments is great."
"It is a nice licensing model and it makes it quite simple because we just pay for what we use, and the bill that comes shows us exactly what customers are using what resources."
"For our use, it's appropriately priced and overall, it's proved to be very cost-effective against other tier-one vendors."
"One of the factors that ruled out several providers was cost. They were way too expensive for the volume of data that we needed and the speed at which we needed to be able to manage it. There aren't a lot of providers that can do that."
"The price of Zadara is very good and it covers everything. There is no subscription needed."
"The pricing and licensing are very simple and the cost is predictable, although, like everything that you pay for as you use, you have to be mindful of what you're using."
"If you just take the street price of Zadara Storage Cloud and look up the price or cost per hour, then you could think that Zadara Storage Cloud is extremely expensive or a solution only for enterprise use. That is not true. You need to compare the entire system. This means that you don't stop looking at just the street price, but you need to consider all the features, requirements, and costs of support as well as the extra cost that other vendors have. Other players just play with hidden, additional costs. Everything is included in Zadara Storage Cloud's licensing cost; what you get is what you pay for."
