We performed a comparison between Dell Unity XT and Hitachi Universal Storage VM [EOL] based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."For us, the most valuable feature is the compression and deduplication. Being able to deploy a three to one ratio for storage is absolutely critical in today's world with the growing need for storage and the growing need for more space."
"We are very happy with the data deduplication and compression ratio that we have on the platform."
"The back-end data reporting for Pure Storage is phenomenal. The data that you can see on the performance of your customers' array, so you can be proactive about upgrades or enhancements, and is a phenomenal tool to have access to as a partner. I haven't seen this type of stuff out of anything of the other storage systems."
"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."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"The solution helps to simplify storage."
"Their support system has insight into errors on our SAN fabric that we can't see. They've brought attention to and raised awareness for us about things that we couldn't see, when we were experiencing problems."
"The security operating system is its most valuable feature because it's very simple, easy to use, and operate. You don't have to do very serious training to operate this equipment. It's user-friendly and pretty straightforward."
"The most valuable feature is the dynamic cache of this product. It is very important. We have the physical cache and we can boost this cache using disks. All the products are mainly flash now and this is one of the main characteristics which our customers like."
"It has good performance."
"The All-Flash models are pretty fast for the vast majority of our remote workloads."
"The most valuable feature is the fast cache with functionality rewrite."
"There are also DR and data protection functions that we found in the new Unity, now that we are stepping up from VNX and other storage appliances, that we've started implementing."
"The replication is big for us. We use file services on Unity and it has a really nice file services interface. It's also easy to manage. It's really easy in terms of provisioning, replication. There are no real tricks to it. It's just easy."
"It can be simple to deploy, the standup time is quite quick. The interface is quite quick. The terms are simple, intuitive, it's similar what was there in the VNXE before it. It's very simple to navigate and administer from the console."
"The feature that I have found most valuable is the unified storage. Also, its capabilities for block-access, file access, and the center box."
"The most valuable features are simplified provisioning and management, de-duplication, and built-in encryption."
"I would rate this solution an eight because we have had outages. The commit times went very high in the database. The whole array went down so our customers were down for around eight hours. This was a very big outage which could have been our fault because we didn't do the upgrade in time."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool."
"Currently, the solution fails to support file screening."
"I would love to see a true one click upgrade solution. Right now, you have to click and schedule an appointment with Pure Storage to be able to upgrade. I would love for it to automatically download, install, and fall-over every controller as it updates."
"CIFS and SMB Shares cannot be mounted directly."
"The solution could improve by having a multi-tenant feature."
"If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."
"We haven't seen ROI."
"Thick provisioning of LUNs."
"We had one incident with a memory leak that led to controller reboot. Although it had no impact, when such things happens the storage should be more aware of it, send alerts, and propose corrective actions."
"Last (and I understand that it has a low chance of being implemented) the copy services currently are redirect on write. It would be great if the administrator could choose between redirect on write and copy on write, when configuring copy job."
"It's not as reliable as it should be, I think it was probably released a little early. We've had production problems with customers, and there are still some challenges at scale as well. Compression is a problem for the system. Once you enable dedupe and compression, the performance of the system, the capability, halves... It has to be right-sized and sized for compression, but even with that, because there are only two storage processors, you're ending up at almost 40 percent usage."
"Ordering is easy, but the processing site and working with those companies was difficult."
"Compression and block deduplication on non-all-flash solutions."
"In the dashboard there could be notification of duplicate files and the like, so we don't have to rely on Windows to do that."
"Issues with slow responses from the support team."
"The exterior display needs to be improved."
