Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."It is all-flash. This makes it a lot faster than the rest of what we have, as it is able to drive high I/O loads, which is big for us."
"Pure gives us better compression, it's easier to manage, a lot less hands-on."
"The most valuable feature of this solution is the support."
"The job of support for the storage engineers dramatically changed. We know more quickly the automation of the provisioning. We can now focus on things that bring more value to the company than just managing storage."
"The sales and executive support have been outstanding compared to the rest of the market... My upgrade paths have been simple on the Pure... It's a lot simpler to implement and a lot simpler to manage."
"The most valuable feature is that maintenance is free."
"The performance and the ever-growing maintenance are the most valuable features of this solution."
"Pure Storage technology allowed us to automate tasks, reducing something which started as a 12-hour turnaround down to about 15 minutes."
"We have been able to consolidate storage into Pavilion. Pavilions are our only SANs because it is a bring your own disk solution. When new drives come out, we are able to take out half of the drives in the system, put in new drives, move our VMs over to the new drives, take the other drives out, and populate those with new drives. Then, we are suddenly twice as dense as we were before. NVMe flash is only going to get denser and cheaper so we can make use of that every couple of years by just throwing newer disks into it at a fraction of the cost of a new SAN."
"There's lots of flexibility in how we use the resources while also maintaining a small footprint."
"The high performance is very valuable, as well as the enterprise reliability features."
"VIOLIN QV2020 is the latest in terms of performance. It has high-speed data access and processing capabilities, distinguishing it as a leader in its storage solutions category."
"It’s simple to use hardware to fix performance issues. Our issue is poor coding/queries. This greatly speeded things up. It’s too costly to track down poor programming in applications. The price of a developer’s time to scan through all the coding is high compared to buying Violin."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"They are doing some stuff with containers and an object search. These could be improved, because containers is one of the main topics that we are talking with our customers about."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"I think replication is one area that still needs improvement. Earlier, Pure Storage FlashArray only had IP-based replication. There was no API-based replication, but they have enhanced the feature now. However, they need to work on API replication for C-type of arrays."
"In the next release of this solution, we would like to see automated copy data management for SQL Server."
"In the next release of the solution I would like to see Vormetric native block encryption."
"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."
"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says its completely full. This is because their dedupes are saved as space, but Vcenter still detects the disk as completely full. So, we do have an issue with that."
"In our current configuration, we can only run the line controllers in high availability, active-standby mode, whereas we would like to see active-active implemented."
"The rail system that Pavilion uses to mount up into a standard Dell or APC cabinet extends further back than normal rails, and they cover up the zero PDU slot. So, I don't like the rail system that comes with the device. That is my biggest complaint."
"I would like to see the management layer improved."
"VIMM replacement is poorly designed. You have to slide out an entire drawer, remove the cover and then pop out the failed VIMM. I would like to see a front replacement just like with hard disks. This leaves room for error; for example, when you slide it out from the rack, you are moving cables along the cable management arm. This leaves the possibility of accidentally unplugging a cable from the array if it is not seated properly. Also, you might pinch the cables when sliding it back into the server rack."
"I set up Wi-Fi for storage, and since then, we haven't experienced any interruptions in service."
