High performance and throughput enhance IT backup management

The multi-dimensional scale-out design feature of Pure Storage FlashBlade is not in use in our environment. Regarding data reduction technologies, we don't get much deduplication because the data is already deduplicated from our FlashArray before we get to backup, so there is no benefit of deduplication. Regarding the integration with cloud-native ecosystem tools, we are not on cloud; we are strictly an on-premises solution. Pure Storage FlashBlade is not used by any end-user; it's used only for IT backup, with only about four people in our group managing it. I cannot recommend Pure Storage FlashBlade to other users depending upon their financial situation because it's an expensive solution, and the cost is very high, including licensing and renewal every year. I rate Pure Storage FlashBlade an eight out of ten.

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.

Quotes from Members

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

Pros

"Speed and ease of use are the two most valuable features."

"The initial setup is pretty easy and simple."

"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."

"It performs well and it is also very fast."

"The most valuable features of this solution are the rewrite speed and the nonstop services."

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

"The solution provides many controllers."

"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."

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."

"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."

"The best part of the solution is that you can actually scale up to a large number of operating systems without additional hardware."

"The most valuable features of the solution are that it is easy to deploy and the support is really good."

"This is an easy-to-use product for adding flexibility to your storage solution."

"The single management panel is the main feature that is wonderful for the customer."

"The solution is simple to configure and provides good performance and less footprint."

"VMware Software Defined Storage gives higher availability against data corruption."

"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."

Cons

"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."

"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."

"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."

"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 better integration."

"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."

"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."

"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."

More Pure Storage FlashBlade cons

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

"The reporting mechanisms need improvement."

"I'd like to see improved hardware compatibility"

"Simplifying the licensing model and making it cheaper would improve the solution."

"The license model of the product is an area of concern where improvements are required."

"There is room for more integrations and plugins into more storages."

"It doesn't have the ability to be deployed on any kind of hardware and network connectors."

"The performance is not as good as some competing products and reporting can be improved."

"VMware Software Defined Storage should include a shared database on a standard version."

"The solution has some limitations in terms of replication to remote sites or cloud infrastructure, which need improvement."

Pricing and Cost Advice

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

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

"The product is very expensive."

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

"I rate the tool's pricing a seven to eight out of ten."

"Our licensing is renewed annually."

"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."

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

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 product is quite expensive and is among the most expensive for this type of solution."

"A single socket costs you around US $6,000 for three years. At a minimum, you have a three load cluster for a medium or enterprise-scale company. It can get quite expensive because you're likely to need four to six sockets on the other side. It comes to around $30,000."

"I believe there is a yearly licensing fee of around $2000 - $5000. I don't think there are additional costs above that but it depends on the type of infrastructure you're booting."

"VMware Software Defined Storage is a slightly expensive solution."

"The solution is very expensive."
