Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution is very straightforward to set up."
"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."
"The most valuable feature of this solution is its ease of use."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The most valuable features of this solution are its ease of use and performance."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"What I really like about this program, is that it is easy to use and easy to configurate."
"Typically, high-performance and high-availability features, such as application snapshots and remote and local replication, are highly valued."
"The most valuable feature of Dell PowerStore is the all-NVMe flash storage. This is the most powerful feature of this series. It supports compression and duplication leads."
"The most valuable features of PowerStore are its density and data reduction."
"Dell EMC PowerStore is scalable."
"You can add compute and capacity independently. We have sized the solution based on our current needs, but in the future we can choose to increase capacity if we grow our activity in the market. And if we have more business in our monetary system, we can increase compute. The ability to choose what we increase is a good feature."
"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."
"I like the performance of the PowerStore. When you talk about PowerStore, it's mainly about flash systems and high-end IOPS. The 1000T is a midsize box, in terms of the way the vendor positions it, but it is more than enough for our needs."
"The most valuable feature is the unwavering performance."
"The most valuable feature is the integration with vCenter."
"Its main advantage over vSAN was the rebuild, the intelligence of the restoration in the event of a hardware drive failure and, of course, the all-flash solution."
"This solution makes it easy to manage storage, provision new workloads, and scale-up."
"Via a click, we can deploy a data store or LUN to the ESX host. We can also deploy VVOLs to the ESX server."
"I like Unity XT's software-defined storage. It's a new feature that isn't widely used yet, but customers are impressed with it."
"The technical support is very professional and provides quick responses."
"The way it takes the Snaps, that is one of the best features. Snapshot performance is what is key in the Unity, compared to a traditional VNX."
"Provides good provisioning, allowing us to save space."
 

Cons

"There is room for improvement in the pricing of the product."
"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."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"I'd like to see the product implement active replication for vehicles such as VMware."
"The UI for this solution needs to be improved."
"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."
"We need better data deduplication."
"In the future, I would like to see integration with enterprise backup systems."
"Where the system needs to improve is by adding more enterprise features like replication on other sites. We would also like it to be much more aligned with the VMware version. For example, today we have two different versions of VMware ESXi running to keep the PowerStore online. It would be better if the software cycling was faster."
"The only area I can highlight for improvement is that the 4:1 data reduction target has not been reached. This may be due to an issue with Dell EMC's initial analysis of data compression. As a result, we have had to add new physical disks to reach our goal of total available disk space."
"We need to find a way to ensure the cache data is safe and secure."
"We are happy with the service in general. The only thing would be the price of the platform."
"It's also only supported with a limited amount of switches."
"Sometimes, you have to go back and forth with the technical support team, where they want you to do something you've already done."
"Dell PowerStore is a good solution overall, but some models could support hypervisors better by allowing for more customization and flexibility for customer needs."
"We would consider this solution if the pricing is competitive with other options, as it offers a very good solution. However, the current price is slightly higher than the competition."
"The only challenge I've ever had was with a Drive firmware upgrade."
"Our request to Dell EMC for improvement was in the reporting and monitoring areas. Dell EMC built up a cloud ID so that we could see the overall storage numbers. We needed to have the proper KPIs to be able to see and manage things."
"I'd like to see more of the NVMe back-end for the flash. And the big deal with the PowerMax is that they've used all U2 drives so that they can avoid having to take it down. I see using M.2 and modular sections as being a real nice alternative that could be implemented in Unity at a fairly low cost."
"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."
"​Improve the interface and provide more management capability."
"My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint. We were trying to run some commands just to see how the storage snaps were interacting with the storage array, and it was a little difficult to look up exactly what commands should be run. The Help files detailing what exactly the commands did wasn't as detailed as we would have wanted them to be."
"Dell Unity XT could add a unit-to-unit replication. We haven't seen that because we don't have an additional one to test. However, it is not an improvement, but something that we would like to have visibility on how it's done or how it works."
"This product lacks deduplication and compression at the current version 4.1.0. LACP is not available for iSCSI either."
 

Pricing and Cost Advice

"With VMware, we pay $300,000 annually."
"As far as the licensing costs, everything is included in the license."
"Our licensing fees are $500,000+ USD."
"We pay approximately $50,000 USD per year in licensing fees."
"The product is expensive."
"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 licensing is on a yearly basis."
"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."
"There are no separate licenses required as all the basic licenses are included in the bundle."
"The price is not cheap, but it's worth it for the features you get from the storage. If you can afford it, you are probably buying the best solution that you can have for this virtual environment."
"The solution's price was comparable to other products for the use case, size, and setup."
"PowerStore's pricing is reasonable."
"We are happy with the pricing that we get from Dell."
"I rate the price of Dell PowerStore a seven out of ten."
"The price is high compared to the Tunisian market."
"If we use the 500 or 1000, the licensing and pricing are reasonable. PowerStore can compete with any vendor and the price isn't that expensive."
"The solution should be cheaper."
"Licensing is fine. We worked with a sales rep to purchase our Unity."
"Most licenses for the solution are free but upgrades are available when adding additional software or storage."
"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."
"The price is very reasonable."
"There is not a license required for the use of the solution. We purchased a maintenance contract."
"We checked both HP and Dell and we determined that Dell EMC was a better option."
"It was easy to order. We are a big Dell shop, so it was easy to purchase and get it in place, then up and running."

The Unity 400 is a rather old, a much less powerfull solution and at its best holds ssd flashdrives if at all. Currently you have the Unity 8xx 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 storage, 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, probably due to half its blocksize. The price of the device is pretty much dependant on the price of its media, and therefore the Powerstore T1200 is the absolute winner. . 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. . 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, though some still prefer the Unity for NAS compared to Powerstore, but honestly speaking I won't recommend to use any of both for that purpose unless for limitted useage. Unity allocates RAM ressources dynamically when used for FC/SCSI AND NAS , whereas the Powerstore is initialized in a kind of split off of RAM ressources between NAS/FC SCSI at installation time. The ressource allocation is fixed and can't be altered lateron.  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.
