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.

Provides efficient synchronous mirroring capability and dynamic data management functionality

The initial setup is relatively easy but requires a certified DataCore implementation engineer to deploy the solution in a production environment. The deployment following the qualified procedure, typically takes about a week, depending on the amount of storage and the specific environment. With my experience, I can set up the system within two to four hours; however, the qualification process, which includes detailed planning and testing, adds additional time. It involves gathering the customer's requirements, preparing comprehensive documentation for validation, and conducting tests in collaboration with the customer. This documentation includes a site planning checklist, a pre-installation checklist, and a functional test plan to ensure everything is in order before deployment. Overall, I rate the process an eight.

"The solution provides many controllers."

More Pure Storage FlashBlade pros

"SANsymphony is flexible, with many potential options for implementation. SANsymphony's can be used with VMware, Hyper-V, or even with a hypervisor agnostic approach. It can also be used for strictly physical non-virtualized solutions."

"The most valuable feature of DataCore SANsymphony SDS is its high availability. This solution also exhibits good performance and has high stability."

"It is a stable solution."

"The use of the RAM cache allows you to speed up the writing and reading of data while also allowing for a possible increase in performance by increasing the RAM on the servers."

"The solution's most valuable feature is its versatility, with there being support for all new hardware technologies and platforms, disc mirroring and very effective auto tiering."

"Good security with this solution."

"The most valuable feature for us is that we can adjust the size of the storage very easily, without stopping production."

"I found the solution to be very stable."

More DataCore SANsymphony pros

"It's mainly about the storage expansion, like in hyper-converged solutions."

Cons

"They need better integration with public clouds along with a better hybrid solution."

"It's on the expensive side, as expected for a niche product."

"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."

"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 also like to see better support for CIFS workloads."

"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."

"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."

More Pure Storage FlashBlade cons

"Datacore is developing a new WebUI with new dashboards. It is a good idea as the classic GUI is lacking dashboards."

"I would like to see reporting added, such as a monthly connectivity report."

"If it could integrate to a cloud gateway, then we could carry it directly to storage, instead of having middleware in between the storage and the cloud."

"When I sometimes reboot for maintenance, the connectivity from the iSCSI initiator host could be improved."

"There is room for improvement in the graphical interface."

"For customers or technicians who don't speak and understand English, it would be great to have other language support, all the more so given the number of countries in which SanSymphony is used."

"DataCore should integrate its own file server into SANsymphony."

"I'd like to see the company make the renewal of the software cheaper."

More DataCore SANsymphony cons

"Documentation management could be improved"

"More optimization could be done in terms of mirroring."

"Microsoft closed the shared cluster support, which is important for the solution."

"On a scale of one to ten, I would rate the customer service and technical support of Microsoft Storage Spaces Direct a three, as there were issues that the Microsoft team could not pinpoint, leading to delays in finding solutions."

"The integration is not difficult because there is no GUI, but we need to use a PowerShell command. This makes it difficult to monitor and to see the components' statuses."

"It is scalable, but only beyond two nodes. If I go for two nodes it's not scalable. I need to build a complete cluster from the beginning if I'm going for two nodes."

"Microsoft closed the shared cluster support, which is important for the solution."

"The management tool within this solution could be improved. We would also like to be able to access services like Azure when using this solution."

"The pricing and licensing are better with DataCore."

"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."
