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.

High availability and user-friendliness enhance infrastructure health and redundancy

I would rate technical support from DataCore SANsymphony a 10. Each time I contact the technical support, it's when I don't have a choice because it's very difficult for me on site, and each time, I have good people online who are able to help me solve the problem. Usually, the problems are not very technically difficult, but sometimes they are, and the support team is still there to help us resolve them. The majority of the problems are linked to licensing, so when the license has expired or the number is not correct, they are proactive and change things live, which is very good.

Quotes from Members

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

Pros

"The product is scalable and easy to expand."

"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."

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

"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."

"Among its most appealing features are its ease of handling and minimal maintenance requirements."

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

"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."

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

More Pure Storage FlashBlade pros

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

"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."

"The price of this solution could be made more affordable."

"Licensing fees are paid yearly."

More Pure Storage FlashBlade pricing and cost advice

"In my case, the licensing per terabytes is very high and it must be licensed for each extra functionality."

"This product has a good ratio between quality and price. In many cases, it's less expensive to work with DataCore than other storage systems."

"DataCore SANsymphony's pricing is very high and should be much cheaper."

"We have licensing costs on a yearly basis. They charge per terabyte, so in terms of cost, it can be very costly. They have three different features, and you have to pay extra for those."

"The solution is cost effective."

"Pricing has improved but it is still expensive."

"The cost is at the same level as other storage solutions and it is easy to understand the licensing."

"This solution allows the use of off-the-shelf hardware and charges by the TB of storage."

More DataCore SANsymphony pricing and cost advice

"The solution is very expensive."

"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."

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

"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."
