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.

"The most valuable feature is that it is easy to use this frame. I am a SAN administrator, but I was able to train my colleague, who had only been a VMware administrator, on the PowerStore in about half a day. Now he's autonomous in assigning volumes and creating data stores..."

"This solution is highly flexible and offers efficient online compression capabilities."

"The product is reliable and stable."

"The solution is stable."

"Dell PowerStore is a price performance product positioned as mid-range, making it the best fit for our needs."

"The latency and the security are the most valuable features of Dell PowerStore."

"Overall, we're quite happy with the product because we can move the data that is stored on more than 10 of our current storage devices to a single PowerStore."

More Dell PowerStore pros

"It is easy to set up the solution."

"The performance combined with the gig-per-dollar value is a combination that is superior to other storage options."

"It has reduced the latency in application and database reads and writes... All-flash, it's fast. We have the 650 model which is all-flash, upgraded from VNX. It just flies."

"I like its performance and support."

"On a scale from one to 10, I'd probably give EMC customer support an 11. It's been really good. We do have premium support, which means if we have a problem, it gets solved really quickly."

"It has compression, which allows you to store more data than you would normally under the arrays."

"The multiprotocol support. It's supporting NFS, fiber channel, CIFS, and these kinds of things. The multiprotocol is very attractive."

"We were able to integrate it very quickly with other solutions."

More Dell Unity XT pros

Cons

"They could add more support for file storage and different types of storage."

"I'd like to see the product implement active replication for vehicles such as VMware."

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

"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."

"It is on the expensive side."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"The tool's portfolio is minimal. It is expensive."

"I would like to see replication and DR features in the next release of this solution."

More Pure FlashArray X NVMe cons

"One of the big differences when we were looking at Pure is that they had more of an in-place upgrade option going forward, kind of future-proofing things. We hear Dell is working towards that, but they weren't quite there, especially three years ago."

"Dell PowerStore does not have features that specifically cater to the needs of our company or industry that are outstanding among others, but reliability is crucial, and ease of management is also important."

"The pricing point must have better positioning. It is somewhat expensive compared to the competition."

"Many customers are looking for a cyber recovery feature included in PowerStore. We would like to see this added in a future release."

"Dell PowerStore does not meet the needs of a small organization; Dell has Unity which meets the entry-level or SMB segment."

"The replication part needs improvement, particularly the integration of RecoverPoint."

"The storage could be improved. I would like a feature for how to best secure an appliance and the storage since we are connecting the container to the public cloud. I would like them to develop another level of security, making it more secure than from what they have now."

"The support is not very good."

More Dell PowerStore cons

"This solution could be improved by offering containerization. This is something many of my customers are looking for."

"Stability is the problem. We've had stability issues with it. We've had problems with the iSCSI interface. We've had it for two years now and for two years we've had problems where a service processor will drop, we'll lose connectivity to LUNs, we'll lose connectivity to the storage, issues like that. No matter how we've tried to chase it down, everybody just points fingers at each other. The only thing that changed in our environment was that the Unity solution was installed."

"The NAS capabilities of Unity - I have to say there are a lot of things I miss. For example, deduplication for hybrid. I have tons of customers with VNX and dedupe. These customers achieve around 50% dedupe efficiency and they mostly use them for archive. If you're talking about 50TB of NAS, which is stored in a 25TB repository, which is very economical, and you can not provide that in a Unity hybrid box, you have problems."

"I think Dell EMC should be more careful in appointing partners, and they need to have better control over their partners. And if their partner has some problems with them, we should not suffer."

"Improve the interface and provide more management capability."

"A customer had to buy VMX because Unity didn't have WORM."

"The upgrade process needs improvement. I should be able to swap it out, with zero downtime, with another array, down the road. I don't think Dell EMC has anything in the roadmap for this product line. I just don't want to have to deal with that anymore and all of our customers are pretty much the same."

"Dell Unity XT could improve the compatibility of some of the features. Some of my customers had some problems. Additionally, it would be beneficial for the solution to have advanced AI and ML features."

More Dell Unity XT cons

Pricing and Cost Advice

"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."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

"The product is expensive."

"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."

"The support cost per array is about $20,000 a year for 24/7 support."

"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."

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

More Pure FlashArray X NVMe pricing and cost advice

"The licensing for this solution is good and is in the mid-range tier."

"Dell PowerStore charges for the hardware warranty every three years. The price will depend on the storage model or how much hardware it has."

"Dell PowerStore is not a cheap solution."

"The price of Dell PowerStore could improve. The price should be managed more compared to Huawei Dorado or IBM All-Flash series."

"We only have a single machine and we are currently using half of the hard disk slots. We have asked for an upgrade for the rest of the hard disks but, from my point of view, it costs too much. We have 12 to 15 hard disks inside and if we try to upgrade only the hard disks, it costs the same as the complete system. This is something I don't understand."

"It is easy to work with Dell from the licensing perspective."

"We purchased it with a five-year warranty."

"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."

More Dell PowerStore pricing and cost advice

"We purchased a five-year warranty."

"The pricing is reasonable. We're using the Flex on Demand pricing. It's really good for us when we pay for what we use. It made it easy to get it inside since it's an OpEx and instead of CapEx expense."

"There is no capacity license for XT and no additional costs for expansions. I would rate its pricing as four out of five."

"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."

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

"The solution is very expensive."

"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."

"When you look at what Dell EMC is compared to, like NetApp, they're all priced pretty similarly. I think the pricing of the hybrid model is good."

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."
