Helps to save money and resources with the data compression feature

One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Integrated AI and clustering enhance storage operations effectively

I promote and recommend Dell PowerStore for all workloads to my clients and customers. Most of my customers have one appliance per site. Approximately 80% of my customers have Dell PowerStore implemented in their data centers. We always use CLS as another Dell solution for cybersecurity and data security. The CLS is integrated with the Data Domain, PowerProtect Data Domain, not with Dell PowerStore. Windows, Linux, and some customers use Red Hat or SUSE. We have many operating systems working with Dell PowerStore in the same environments and data centers. CloudIQ and Storage IQ are used by some customers, but Apex AIOps has not been widely adopted yet. Dell PowerStore has integration with VMware and Kubernetes. Most workloads work fine and have very good integration with Dell PowerStore, except for one or two specific workloads in the market. On a scale of one to ten, I rate Dell PowerStore a nine.

Efficient data replication and fast IOPS have improved operational performance

Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.

More Dell Unity XT pros

Cons

"The software layer has to improve."

"In the future, I would like to see integration with enterprise backup systems."

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

"Maybe the price can be reduced since the solution is very expensive."

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

"The tool's pricing is higher than competitors."

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

More Pure FlashArray X NVMe cons

"We need to find a way to ensure the cache data is safe and secure."

"Sometimes, you have to go back and forth with the technical support team, where they want you to do something you've already done."

"The cost of technical support is high."

"One improvement I would suggest relates to the service that pings Dell when there's an issue. I would say it needs to be more transparent."

"One thing they need to work on is creating an app sync or the Metro Cluster functionality. Currently, it requires a different hop as we have to add multiple switches to build that functionality for replication from one data center to another."

"The customer support is slow and has room for improvement."

"PowerStore's management console could be improved."

"Having all the services consolidated makes it hard to scale."

More Dell PowerStore cons

"There is an ESRS problem that we're facing where, for some reason, the other Unity has not been able to register to EMC. The support information is not upgrading and nobody can tell me what is wrong with it. It's a minor issue, the ESRS is still working, but it is something that is very confusing and nobody seems to know what to do about it."

"In terms of what could be improved, I would say the deduplication part, because for large deduplications, you need an extra appliance to do it in order to avoid having problems in performance. I think that could be improved, because everything should be included in the product, not with an appliance from the outside."

"We would like to see the concept of Storage Groups brought back to this product line."

"I would like to see more integration with other products."

"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."

"The support portal needs fixing. Accessing a service request on the support portal seems to be a bit difficult, as opposed to just calling the 800 number."

"I haven't seen the roadmap for this solution."

"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."

More Dell Unity XT cons

Pricing and Cost Advice

"As far as the licensing costs, everything is included in the license."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"Our licensing fees are $500,000+ USD."

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."

"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."

"With VMware, we pay $300,000 annually."

"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."

More Pure FlashArray X NVMe pricing and cost advice

"The pricing structure and licensing model of Dell PowerStore are pretty decent. It's pretty competitive."

"PowerStore's pricing is reasonable."

"We are currently using Dell PowerStore for our smaller storage and there is no competition for pricing."

"Dell PowerStore has been priced aggressively, especially when compared to other NVMe storage options. It is likely one of the most cost-effective options for organizations seeking a pure NVMe play in terms of pricing."

"Dell PowerStore is more expensive than Dell EMC Unity All Flash. Dell PowerStore's performance metrics were way higher than what Dell EMC Unity All Flash offered."

"There's still a cap on the upgrade path, where you can consume all the engines within the frame before you have to go to another frame... Normally, we exceed the IOPS on the frames before we can ever exhaust the storage, so anything they can do to help us avoid stranded storage capacity, capacity that we couldn't get to, would be beneficial."

"I rate the price of Dell PowerStore a seven out of ten."

"The rate is always too high. Nobody likes paying for it. I have not seen a client yet who says that the price should be higher. Initially, people look at it, but when they see what the benefits are, it is a no-brainer. We can give them good pricing at the outset."

More Dell PowerStore pricing and cost advice

"Pricing is as high as it has ever been for EMC."

"We integrated it with VMware vSphere at no additional cost. As we moved into VMware vSphere, this is what we bought to go with it for our storage performance."

"There is not a license required for the use of the solution. We purchased a maintenance contract."

"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."

"The price is up a little bit from what we used to pay so I'm hoping that it's a little bit of a better system than the VNXe was. But I still think it's a good value. It's new, so I'm sure there's room for the pricing to drop."

"It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options."

"Because of the attractive price, we were able to get rid of more expensive arrays, standardize, and get rid of a lot of spinning disks. We also got rid of more expensive flash that we weren't properly utilizing."

"There is an annual charge for the license of this product. It has better pricing than its competitor: Pure Storage."

Cloud Engineer at a tech services company with 51-200 employees

Sep 19, 2023

The Unity 300/400/600 generation (1st) is really old stuff, lateron came the 2nd generation of 350f,450f,650f (hybrid or full flash) and still later cam in the 3rd generation 380f, 480f,680f & 880f As usual the CPO/Cores and cache increased everytime, the code is pretty much the same. The x00 generation is already obsolete and by next year the next generation x50 is going to be obsolete from a service point of view. Here is how it goes. Dell Puts forward to replace * the Unity XT 380F by an Powerstore 500T * the Unity XT 480F by a Powerstore 1200 * The Unity XT 680f by a Powerstore 3200 * The unity XT 800f by a Powerstore 5200 There is even a Powerstore 9200 Currently you have the Unity x80 model, which has more CPU punch and therefore maxes out less fast on CPU utilisation. What this means is that you can add more shelves and disks and workloads to it before you hit the roof. The powerstore 1200 is an nvme/FC but NAS storage as well, is 60% more powerfull (compared to FC/SCSI-SSD on Unity) in our case, and has higher datareduction rates. If the unity reaches out to a datareduction rate of 1.5 or 2, the Powerstore T1200 is capable of 3 to 3.5 datareduction. the Powerstore offloads its compression/deduplication efforts from the Processor to a hardware component in charge of it (like the PowerMAX and likely the same device and Compression Algorithm). The price of the device is pretty much dependant on the price of its media, and therefore the Powerstore T1200 is the absolute winner as you can double the data saved to it compared to the Unity alternative. There is one caveat, when you initialise your Powerstore you either initialise it as a NAS or Block Device appliance. Whereas on the Unity part, you could use both options at the same time.. Another aspect is that the Powerstore can be used to build a cluster of arrays compared to the sync/asynch replication only feature of the Unity series, rendering the mirrored volumes unuseable unless one fails over to it, like in a disaster recovery scenario.To you can , have true Active/Active volumes and go next level with MetroCluster volumes and go beyond VMware Site Reovery Manager to organise your failover/test failovers and protection groups. You can actually leave aside VMware Site Recovery manager and do all from within Powerstore and use its Recoverpoint for VMs add on (similar to Veaam replication but a with an storage appliance in support. The Powerstore also allows true A/A volumes on both sides . What this means is that one can build stretched vSphere clusters and the loss of your array in one site will still allow writing to the alternate protected disk, transparently ! You can have site local writes to your volumes and remain in sync without a need to cross site write. There is not much of a reason to settle for the Unity anymore, unless you would go for a mixed chassis providing both Block Storage & FileSharing. Unity allocates RAM ressources dynamically when used for FC/SCSI AND NAS , whereas the Powerstore is initialized as either a NAS or BlockStorage at installation time. Thats a hard call. So I'd favour the Unity only if you use it for low/moderate NAS needs in combination with FC/SCSI or block data and you don't have the budget nor the size to use a NAS optimised array on top.

Reviews from Real Users

Below are some reviews and helpful feedback written by Dell EMC Unity XT users.

A Systems Engineering Manager at a manufacturing company says, "It is definitely one of the most robust, solid, well-performing products that I have dealt with. It is set it and forget it, which is pretty amazing." He also mentions, “We can do both block and file storage on one unit without purchasing a separate device.”

Peter S., Senior Technical Specialist at a healthcare company, states, “The most valuable feature is reliability. At the end of the day, it just runs. This solution is easy to work with and easy to maintain.”

PeerSpot user Melvin T., Senior Systems Engineer at Prosperity Bank, explains that the solution is “easy to use and we can add LUNs or space without interruption to end-users. We're able to access it from just about anywhere, as long as we have access to a browser. That feature is really neat because sometimes we will go to a different data center or a different site, and if we need to access it to see a LUN or to see any type of storage, we can do that. That's one of the big takeaways with Unity."
