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.
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.

Quotes from Members

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

Pros

"All-flash is a game changer. If you need performance, simple operations, and you plan to use it with VMware, it is a good choice."
"Scheduled components are sourced from Korea based on their quality selection, with the actual purchase taking place in Vietnam. The notable features include cache memories and MOS feeder in Dell Unity. Additionally, the storage dynamics are managed uniformly on a global scale, whether it is a simple or wide-ranging configuration."
"The Unity XT box is very strong. It doesn't break. The MTBF time is very large so you don't have to worry about faults or outages in your operations."
"Stable data storage platform which promotes ease of management through its multi-cloud support. Remote support provided to users to address issues is very good."
"It is ease to use. It performs. It's easy to provision, and It's stable."
"It has helped us be able to use less administrators per device or system. Therefore,we are more streamlined."
"It is easy to manage. A lot of the system manages itself."
"The most valuable features include snapshots, Thin Clones, and deduplication and compression."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"It has good, reliable, fast storage."
"The high availability of the product is the most valuable feature."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"I appreciate the performance."
 

Cons

"The only issue is with the product's scalability because it's not as scalable as the other polished tools in the market."
"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."
"What I'd like to see is a little more detail on the networking side. I can go into where it's showing me the replication, but when I go into the network it just gives me broad-based information. I don't know which replication job is actually feeding it. I have to go in and rely on other apps."
"We went to the PowerMax because of the needs that we have for the business. We're doing true enterprise-level storage. So we went from Unity to PowerMax to give us that tier that we were looking for."
"Things that could be improved include one-to-many replication, data deduplication, and asynchronous Fibre Channel replication. It is asynchronous on iSCSI and I would like to have that on the Fibre Channel. Unisphere-wise, I have to log in to each Unity as a unique environment. In VNX, I logged in to the domain and I was logged in to every VNX. So that's missing."
"Last (and I understand that it has a low chance of being implemented) the copy services currently are redirect on write. It would be great if the administrator could choose between redirect on write and copy on write, when configuring copy job."
"It would be better if there were more integrations."
"They can certainly improve in terms of monitoring."
"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."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"We need better data deduplication."
"There are some challenges with data encryption and reduction."
"I'd like to see the product implement active replication for vehicles such as VMware."
"The UI for this solution needs to be improved."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"They could add more support for file storage and different types of storage."
 

Pricing and Cost Advice

"There is no capacity license for XT and no additional costs for expansions. I would rate its pricing as four out of five."
"The price is good for commercial grade storage arrays."
"The pricing is competitive. We miss some of the feature functionality that we had with the XtremeIOs but it's certainly suitable for the purpose."
"Licensing is a little bit confusing. Going through everything with them, there are a lot of line items to go over. Every single thing is broken down into a line item, and it starts to get really confusing in terms of what we're actually purchasing when it comes to the product."
"At the end of the day, the licensing cost is key, because every customer has a pain point, that the cost of each piece is high. So if they would bundle everything in a package, that is how the competitors are selling their footprint."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"Our CAPEX was close to $42,000 and operating costs are below $1000."
"Our costs are roughly $200,000 a year."
"As far as the licensing costs, everything is included in the license."
"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."
"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."
"With VMware, we pay $300,000 annually."
"We pay approximately $50,000 USD per year in licensing fees."
"The product is expensive."
"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."
