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.

A solution backed by strong customer support, that is stable and scalable

As a company managed in a Kubernetes environment, being trusted by a Kubernetes vendor, Red Hat creates barriers against using other certified solutions that work. Because IBM is a competitor of Pure Storage, things seem to be getting worse. I don't have plans to use Portworx Enterprise in the future because, at the moment, I am working with Ondat, and I have to follow NetApp's direction on that. When evaluating Portworx, one should make sure their company has already chosen Pure Storage. Still, if they are evaluating the solution on Ondat or Dell or other platforms, they should get a roadmap statement from Pure Storage, that they will continue to develop storage hardware diagnostics. I rate Portworx a nine out of ten.

Quotes from Members

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

Pros

"We can capacity plan at a greater level than we used to."

"The product is scalable and easy to expand."

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

"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."

"The main feature I have found to be product replication."

"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 tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."

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

More Pure Storage FlashBlade pros

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

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

"A custom IBM script is designed to tackle the storage management challenges within containerized environments, providing crucial data services and features required for enterprise applications."

"I like that you have a small dedicated file system that is fast and resilient for containerized workloads."

"Portworx is a simple solution. It's similar to Pure Storage products. They're all easy to use and install. You need to have a little expertise with containers to use Portworx, but it will be no problem for you if you understand containers."

"The solution is user-friendly."

"Portworx virtualizes the aspects of the underlying block storage. That is good because they can also use block storage for their future deployment instead of just NFS."

"The best thing about Portworx is the Stork, they have called the VPS (Volume Replacement Strategy) and they also have topology awareness, and these are the three features I like."

Cons

"I would like to see more deduplication."

"It would be nice if you could store file-based in the same box with the same technology."

"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 would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

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

"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."

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

"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."

More Pure Storage FlashBlade cons

"The reporting mechanisms need improvement."

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

"It would be highly advantageous to include an integrated backup solution within the same license, rather than purchasing backup separately."

"I think the vendor could provide more training for new users who may not be familiar with containers."

"The integration has room for improvement."

"I would like to see a more native mapping to mainframe-type systems."

"The documentation could be better."

"They have not integrated Portworx with Ondat since they are too focused now on Pure Storage APIs and not on users like us."

Pricing and Cost Advice

"The pricing for FlashBlade is between cheap and moderate."

"Our licensing is renewed annually."

"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."

"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 product is very expensive."

"The price is a little high."

More Pure Storage FlashBlade pricing and cost advice

"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 price is competitive, but it is too expensive when paired with Red Hat IBM."

"I'm not sure how the licensing was broken out, but I don't think our offering of the Portworx was more than USD $20,000."

"It has two offerings. One is free, which is limited to only five nodes. The other is enterprise, which is a bit pricier."

"The price of Portworx Enterprise is high."
