Has handled backup storage needs reliably and supports seamless upgrades
In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

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

"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 performance of FlashBlade is excellent. It does not necessarily leverage the SOS API that some of the newer products leverage, but I found its speed pretty much on par and comparable. It is fast, and it does what it is supposed to do."
"As a Pure Storage platform, the cost-benefit is hugely based on the deduplication and capacity."
"Speed and ease of use are the two most valuable features."
"The solution provides many controllers; more controllers lead to higher performance, and it is a unique feature provided by the product that other tools do not have."
"Among its most appealing features are its ease of handling and minimal maintenance requirements."
"Using this solution has made our backups more reliable."
"It uses the same platform for connectivity so integration is seamless."
"Implementing this solution has been a very good decision for our in-house data center."
"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."
"The ease of use is the solution's most valuable aspect; it's very user-friendly, and the security on the product is very good."
"It's very easy to expand and compared to other storage systems that we've used, it's a lot more expandable and a lot more flexible in how it's deployed."
"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."
"Zadara was a key enabler for us to be able to enter the cloud business because if it wasn't for them, it would have taken us a lot longer."
"Compared to us trying to do this ourselves, we've probably seen about 50 to 60 percent in cost savings over the last five years."
"Zadara is all-flash so it has a very high IOPS."
"We have seen a return on our investment with Zadara storage, and it's because it has enabled us to deliver almost limitless capacity."
"With Zadara Storage Cloud, you simplify the management, which is absolutely true."
"The most valuable feature is the flexibility in terms of deployment options."
 

Cons

"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."
"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."
"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."
"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."
"I have not seen ROI."
"I would like to see more VM-Aware features in the next release of this solution."
"In my opinion, one way Pure Storage FlashBlade can be improved is by having more compatibility between the FlashArray and FlashBlade, allowing for synchronized data between both platforms."
"They need better integration with public clouds along with a better hybrid solution."
"The reporting mechanisms need improvement."
"he interface is not user-friendly so the ease of use could be improved."
"The reporting mechanisms need improvement."
"The interface is not user-friendly so the ease of use could be improved."
"Cost-wise, because it's a pay-per-use model, it may ultimately end up costing us more in the long run than something we developed ourselves."
"We had a lot of issues with the Zadara recently regarding performance, reports, and offloads, the customers could not send backups to Zadara."
"Right now, to use Zadara, you have to go through some hoops."
"The initial setup of the solution is complex."
"I would like to see them be a little bit more proactive in terms of the patches and updates that are available. I would like to see more disclosure and information around what fixes or what enhancements are available within a patch, and help in coordinating and scheduling that. Right now, it's driven more by the customer in reaching out via a support ticket."
"Currently, when we do firmware upgrades, it sometimes causes issues and is not as nondisruptive as desired."
"Some of the features are a little bit slow to come to market."
"The cost is not favorable as Zadara does not provide competitive rates for regions like South Africa and Ethiopia."
 

Pricing and Cost Advice

"The price of this solution could be made more affordable."
"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."
"We used a reseller for the purchase."
"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."
"The product is very expensive."
"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."
"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."
"Licensing fees are paid yearly."
"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."
"If you are cost-sensitive then this solution is not for you."
"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."
"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."
"The price of Zadara is very good and it covers everything. There is no subscription needed."
"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 pricing is very competitive and the fact that they have very compelling discounts for multi-year commitments is great."
"For our use, it's appropriately priced and overall, it's proved to be very cost-effective against other tier-one vendors."
