Eugene Hemphill - PeerSpot reviewer
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.
Brian Ricci - PeerSpot reviewer
It's constantly enhanced and has impressive reliability and data compression
The maintenance is a bit expensive. The service and support are there for three years, but after the third year, it is pretty pricey for renewal. I hope Dell addresses that. Everything is pricey these days anyway. It is not like the old days of Compellent. We used to be able to see the metrics for our customers. On Compellent, we could look up that customer and see all the metrics. That is not allowed for us now. We cannot do that anymore. I have to be explicitly allowed by the customer to do that, and some companies' security does not allow that.
Syed Habib - PeerSpot reviewer
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.

Quotes from Members

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

Pros

"I appreciate the performance."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"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."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"The most valuable feature of this solution is its ease of use."
"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 PowerStore's compression ratio is even higher than the Unity system."
"My company found the tool to be really easy to use, expand, and manage."
"The platform's reliability and built-in replication between disk systems have made our customers happy. It has worked consistently well over the years."
"It is very easy to use. Access is very friendly. It shows you a lot of important information at the first glance. It has been very easy to use."
"The features of Dell PowerStore that I appreciate the most are that it just works; it's tried and true and amazing, and we never have to worry about it."
"When compared to Pure Storage, Dell PowerStore's cost was quite attractive."
"The companies I sell Dell PowerStore to are extremely happy, as they keep expanding it and keep buying more shelves to expand the storage."
"Overall, Dell PowerStore is very competitive in the market and able to beat the competition."
"It is easy to scale, maintain, and manage."
"The NAS is also extremely easy to set up."
"The NAS capability is mainly what we're looking for from this product, and being able to recover fast in DR."
"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."
"The multiprotocol support. It's supporting NFS, fiber channel, CIFS, and these kinds of things. The multiprotocol is very attractive."
"It's the simplicity part of it. It's the ease of management, it's the call home, the CloudIQ functionality. It's all built in. I think Dell EMC has put a lot of thought into it."
"The storage management is superb, with a user-friendly graphical interface and dashboards. The performance is good. The integration, dashboards, and analytics are excellent. It gives me immediate output and quick access to the reports I need promptly. It's an excellent product with high stability. The solution is scalable. The support team is highly supportive, responsive, and efficient in providing solutions. This product is highly useful and well-suited for all types of automation."
"The Dell EMC unity interface is simple to manage. We manage it by ourselves. We create logs to store data."
 

Cons

"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."
"In terms of what needs improvement, the dashboard and management could be simplified."
"They could add more support for file storage and different types of storage."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"We need better data deduplication."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"Adding some functions to the product would be beneficial."
"We are happy with the service in general. The only thing would be the price of the platform."
"Dell PowerStore does not meet the needs of a small organization; Dell has Unity which meets the entry-level or SMB segment."
"The biggest area in PowerStore that needs improvement is the overall visibility within the ESX environment."
"If I could improve the product in any way, I would add features that make it look nicer compared to the DisplayPort."
"PowerStore's management console could be improved."
"The solution's pricing could be better."
"The cost of technical support is high."
"It would have been beneficial to have someone from the support team do a warm handoff to clarify who to contact for future assistance."
"I would like to see better compression, better dedupe. It's not nearly as good as what is built into the XtremIO. I understand why that is the case, but if they can take some of that technology and leverage that a little bit better in the Unity array, that would be great."
"Licensing costs could be reduced."
"There are a lot of things that can be done with it. It's got Cloud IQ, but I think it's not as mature as it could be, they could make it more effective. They could make it more comparable to some of the other products out there that have cloud analytics. The amount of insight that the Unity product is able to give, at this point, is okay, but not class-leading. Some of the other data-reduction technologies, like deduplication, are not to the level of other competitors and what their products provide."
"Unity only does compression. It would be nice if there was a deduplication feature as well. At my previous job, we used XtremIO and that was deduplication and not compression, and I think we got more out of it because the more OSs you have that are the same, the fewer copies it needs to keep of all that data. So, the deduplication would be a nice feature to have."
"Its replication technology could be better."
"This is a tier-three solution and it gives us what we need for archiving and backups."
"There are some features in VNX that I wish were in the Unity. For example, Storage Groups for isolating LANs and hosts. That is a big issue."
"You can't use every feature, because it costs in performance. Therefore, you have to choose which features to use to achieve a better environment. That is why customers do not use every feature in Unity."
 

Pricing and Cost Advice

"Our licensing fees are $500,000+ USD."
"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 licensing is on a yearly basis."
"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."
"We pay approximately $50,000 USD per year in licensing fees."
"With VMware, we pay $300,000 annually."
"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."
"The support cost per array is about $20,000 a year for 24/7 support."
"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."
"It is very expensive though when you get to this point of using the 3000 with a client. They will start to think about using another vendor. There are a lot of solutions similar to PowerStore in regards to networking capacity and their prices are very cheap compared to PowerStore."
"Dell PowerStore is not a cheap solution."
"Dell PowerStore charges for the hardware warranty every three years. The price will depend on the storage model or how much hardware it has."
"It is expensive compared to one of its competitors."
"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."
"With compression, we were able to have a solution within our company's budget. We include a clause in the contract with Dell that states if the compression ratio is not met, we will adjust the workload accordingly."
"The licensing for this solution is good and is in the mid-range tier."
"The solution is very expensive."
"The pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."
"The only improvement would be a lower cost per unit/disks, however on the whole we are very pleased with this product."
"It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options."
"Our CAPEX was close to $42,000 and operating costs are below $1000."
"Licensing is fine. We worked with a sales rep to purchase our Unity."
"Pricing for this product is manageable, though slightly higher than comparable products."
"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."

Hello Yasin, The best solution depends upon your host environment. In general, PowerStore is more powerful than Unity but Unity is also a very good Storage solution.

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.
