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.

President at Pinnacle Computer Services, Inc.

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.

HPC CTO at a manufacturing company with 10,001+ employees

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

"It has benefited my organization because it has reduced time to insights."

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

"The most valuable features of this solution are its ease of use and performance."

"The most valuable feature of this solution is reliability."

"The most valuable feature of this solution is its ease of use."

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

More Pure FlashArray X NVMe pros

"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 initial setup was straightforward."

"Updates come with enhancements. Each time we do an update, there is an enhancement, like new features, which is extraordinary. Other companies would try to charge for all that, but the enhancements just come with it."

"The companies I sell Dell PowerStore to are extremely happy, as they keep expanding it and keep buying more shelves to expand the storage."

"PowerStore is robust compared to the previous models like Unity, and it provides excellent compression and deduplication."

"The compression is excellent."

"PowerStore's compression ratio is a valuable feature for our VMs because it gives us a lot back."

"The solution's migration feature is very valuable, but the most valuable thing is that more features appear with every iteration of the software."

More Dell PowerStore pros

"The solution is useful for machine learning and scientific applications, including computer simulations."

"This has been one of the most reliable storage systems that I have ever used."

Cons

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

"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."

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"Adding some functions to the product would be beneficial."

"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."

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

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

More Pure FlashArray X NVMe cons

"There is no Synchronize replication feature on the storage."

"I would improve Dell PowerStore by enhancing the replication feature because currently, users are limited to one applier, from one cluster, a Dell PowerStore cluster, to another Dell PowerStore cluster, but are not able to configure a three-site scenario."

"Pricing must also be considered, as Dell PowerStore is quite expensive compared to competitors in the market like HPE Alletra, Huawei Dorado, or Hitachi storage, for example."

"It's also only supported with a limited amount of switches."

"The solution’s security and technical support could be improved."

"If I could improve anything about Dell PowerStore, there are a couple of in-the-weeds features that I would want to see, such as the size of snapshots to know when we can expire some of them."

"The initial setup was a little bit cumbersome. We had a bit of an adoption process internally. It wasn't immediately straightforward on day one."

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

More Dell PowerStore cons

"The write performance could be improved because it is less than half of the read performance."

"The read/write ratio is an area in the solution with some flaws and needs improvement."

Pricing and Cost Advice

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

"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."

"The product is expensive."

"Given its price, Pure is not the first option."

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

"The licensing is on a yearly basis."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The pricing structure and licensing model of Dell PowerStore are very good and I like it. We chose it because it was reasonably priced and met our requirements"

"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."

"Licensing is very simple. Everything is included in the basic license. There are no concerns about having to pay to add a feature. Everything is there."

"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."

"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."

"It is expensive compared to one of its competitors."

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

"We are happy with the pricing that we get from Dell."

More Dell PowerStore pricing and cost advice

"Price-wise, VAST Data is not the cheapest, not the most expensive one."

"We acquired VAST Data as a one-time, capital purchase."
