We performed a comparison between Dell Unity XT and Hitachi Virtual Storage Platform based on real PeerSpot user reviews.
Find out in this report how the two All-Flash Storage solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."Pure Storage is extremely reliable — it's never failed."
"At this point, I don't know anything that they could provide in a better way."
"Pure is simple to set up and manage on a day-to-day basis."
"This solution has helped my organization by cutting down on provisioning time. I used to have to provision a VM and it would take ten minutes. Now, it takes thirty seconds."
"Has also helped simplify storage for us. The other person we put in there, took about a week to implement. And we had both arrays set up within around four hours with a thirty minute drive time between the two locations."
"FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."
"Pure Storage technology allowed us to automate tasks, reducing something which started as a 12-hour turnaround down to about 15 minutes."
"Access speed and power consumption are most valuable."
"It is a stable solution that sells a lot...The deployment phase of the product was very easy."
"Stable flash storage platform with good scalability, efficiency, and speed."
"Unity's are more easily administrated, so we need fewer people to do the administration. We have less overhead because of that."
"The compression and deduplication that will be coming in version 4.3. With just those features, you're reducing the amount of data and the footprint on the hardware."
"Unified block and file storage without the need of control stations and data movers. This simplifies administration and deployment and requires less rack space."
"We can get almost real-time response times."
"The product has helpful local technical support."
"It's a much smaller footprint than our older storage arrays, which take up some six tiles, a lot of space in the data center. The Unity's are a lot smaller, and they're a lot faster."
"It is robust. It doesn't need too much troubleshooting. It is a good device."
"The most valuable feature is that it has 'eight nines' availability, 99.999999 percent of the time. That is the main selling point."
"The deduplication is useful for us because we don't have that much money for our lab infrastructure. Deduplication means we have more storage available. And the IOPS are really fast."
"The performance is very good."
"Data optimization, compression, and deduplication are the most important features for us."
"The product provides a good storage space."
"It is very flexible, and it is very useful when you want to virtualize different storage from different vendors."
"We have many different types of replication, such as remote and drop local replication. All these features and licenses are already available. These are basic features available in the current model. Additionally, the performance has been good in our experience."
"A three wave application or multi wave application synchronization would be an improvement."
"The product should improve its response time. I have also encountered issues with its configuration."
"I would like to see a Nagios monitoring plugin which watches the health and performance of the system. The only one available just checks volume capacity."
"A minor issue that comes to mind is that, every once in a while, a hard drive will go bad."
"I want to learn more about command line usage which I have not explored much yet. However, there are many automated solutions for repetitive tasks. I would like to see additional features like performance monitoring, configuring of alerts, and the customization of alert thresholds in the next release."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters. This would make things easier."
"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."
"There is no de-duplication. Unity used to be Bionics, which had de-duplication; however, in Dell Unity XT, the de-duplication was deprecated and is no longer available."
"The Host LUN ID is sequential by access in the hosts. When one LUN needs access by many hosts (for cluster purposes), in some cases the Host LUN ID remains different on each host."
"I would like to see more compression and deduplication added to the solution. Today, our compression is about 2:1 and other solutions give us about 4:1 or 5:1."
"One of the issues we've had is that controllers have crashed several times... We've had a lot of problems with the storage processor, SPBs. We've actually had them crash."
"On the data domains - for the Unity product, but specifically for data domain - I would like a much easier interface for managing, for actually going in and having one place where I could get all of the different parts of the overall unit. And I would also like to be able to identify individual disks a lot more easily."
"We've also encountered an issue when it comes to migrating to compressed LANs on the Unity, and during the Storage vMotion. It appears that the compression algorithm is overwhelmed, and when it becomes overwhelmed it just stops compressing and writes the raw data to the destination. We later copied internally another Storage vMotion to another compressed LAN and achieved much higher compressions on that internal copy. It would be really nice if there was a way to automatically throttle, as a part of a Storage vMotion, to say, "I want to gain the maximum benefits from the compression algorithm, so throttle back the Storage vMotion to implement 100 percent compression.""
"I called about an issue where I couldn't get VVOLs registered. It turns out it is a bug in the code and that there is no information about when it will be fixed. It's just not going to work. I was a little miffed about that."
"Dell EMC Unity XT should present a path or a roadmap on how they could put their products on the cloud. This would have some value for their current customers."
"For the support windows to work, maybe they have to upgrade the firmware of the VSP. They changed the hardware or the disk. I don't know if it was the port blade they changed or a VM for a memory cache. Also, replacing the old target with the processor target would be fine. The old equipment is very easy to manage, and I don't have any bad commentary."
"It seemed like every time we turned around it was a statement of work and we'd have to pay for something that our previous vendors would not have billed us for."
"Hitachi Virtual Storage Platform needs to improve its scalability options where there are a few shortcomings."
"In the next version I would like to see additional features like artificial intelligence and an increase in the amount of data it can store."
"The user interface should be made simpler because it is difficult to manage."
"The user experience is pretty bad in Hitachi. A lot of mandatory tasks take a long time to work through."
"The complex setup, ease of use, and snapshot operations of this product need to be improved."
"I would like to see Hitachi improve their management software. It's been three years since they introduced Ops Center, their management product, and it still hasn't reached at least 50 percent of the capability we require. We are using legacy software because the product Hitachi offers does not stack up in functionality."
