We performed a comparison between Dell Unity XT and Pure Storage FlashArray 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."Overall stability is very good. It is a very stable solution."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"The high availability of the product is the most valuable feature."
"It has benefited my organization because it has reduced time to insights."
"The most valuable feature of this solution is its ease of use."
"We can get almost real-time response times."
"Their support cases are all handed through the portal. The support contacts me when they need to do upgrades. It has been great. It's all very well-handled, scheduled, and performed."
"The performance is great. We have four or five different Unity arrays, and they have all run flawlessly."
"The NAS capability is mainly what we're looking for from this product, and being able to recover fast in DR."
"Ease of use is probably number one, compared to the previous storage that we've had. Easy scalability, easy set up. Compared to everything else, the Unity is, well, you could call it child's play. As long as you know what you're doing storage-wise, Unity is really easy to use."
"They've integrated NAS and SAN pretty well. It made replication very simple. Because one of our systems has a lot of LANs, for it to replicate we have Consistency Groups in there. That's something that is really helpful, making sure that everything is working not just for replication but for backups as well."
"Via a click, we can deploy a data store or LUN to the ESX host. We can also deploy VVOLs to the ESX server."
"The scalability is really good now that they have the Dynamic Pools. We don't always have the money to buy complete write sets when we have to expand the storage, so now with the Dynamic Pools we can add disks on the go."
"It simplifies storage."
"The GUI is very easy to use and intuitive."
"All our junior partners can administer the storage arrays. It is simple and easy to use. We don't have to dedicate a whole team of full time people to work on it."
"The most valuable feature of Pure Storage FlashArray is its high stability level."
"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 deduplication and compression meet all of our system requirements."
"We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."
"Technical support is excellent. I've had very good responses from technical support. We had a couple of cases where we needed support. Some of the communications were purely over email and some has been an actual call to the service desk."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"They could add more support for file storage and different types of storage."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"It is on the expensive side."
"The UI for this solution needs to be improved."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"Firmware Upgrades in EMC Unity require you to manually download OS and Drive firmware, this should be integrated (Nimble does this). When you order an EMC Unity, you have to specify the block size. This is weird for me and even weirder that you cannot change this afterwards, you should be able to specify per LUN/datastore (Nimble does this as well)."
"We are running VMware, and with the VNXe it was possible to restore. We're using Veeam for VMware backups and with the predecessor, it was possible to mount a backup or restore a backup from a storage snapshot. With the Unity 300, this is not possible."
"Maybe deduplication would be something that would be better to have. Also, it's a fairly new management interface, so work is still being done on that. But compared to other vendors and previous EMC storage, the Unity is really good."
"I miss storage groups. Now, if I have to add a LUN to a cluster, multiple host, I have to know which host is in that cluster. I have to write it down and that makes it hard. In VNX and earlier, I could simply put a LUN on a storage group and every host in the group had the LUN. This lack bothers me a lot because it takes a lot of time and mistakes are made. Sometimes, a Hyper-V host gets a VMware LUN and vice-versa. Not good."
"It isn't easy to find trusted partners for the product. The solution has issues with mid-level storage and does not come with enterprise storage."
"The pricing is a bit high. We'd like it to come down."
"I would like the device to have the ability to pull down its own firmware. That would be a great thing."
"I would like to see more integration with other products."
"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."
"I would like to see data tiering to AWS."
"I would love for them to have a hyper-converged solution."
"They have a product, FlashBlade, which is their object storage integration, and that's something that we haven't integrated with yet. This might be an area for additional focus as it would play into scalability, because the very nature of object storage is that it's infinitely scalable."
"The solution could improve by having a multi-tenant feature."
"I would like some form of QoS implemented. As a service provider, it would be beneficial to have it."
"The solution is not cheap."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
