Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades
I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Customer needs are addressed effectively with collaborative sales and service support
Recently, customers have been asking for a cloud tiering option in storages. Some Dell storages do not have cloud tiering, which is an optional commercial feature. NetApp's FSA model 2750 comes with an inbuilt cloud tiering option. In the future, if Dell storages include this option, especially for Unity, it would help us target SME or medium enterprises for quicker closures and support the sales team.

Quotes from Members

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

Pros

"The most valuable features of this solution are its ease of use and performance."
"The most valuable feature of this solution is reliability."
"It has benefited my organization because it has reduced time to insights."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"It has good, reliable, fast storage."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"The initial setup was extremely simple and straightforward."
"It is pretty stable. I like the stability, because everything works like it should. We made it all redundant. So, we don't have anything to worry about."
"It is lightning fast, low on power and heat, and has a small footprint with great performance."
"It is great because it can work as a SAN and net storage."
"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."
"The NAS capability is mainly what we're looking for from this product, and being able to recover fast in DR."
"Quick Snapshots and cloning are key features."
"Dell Unity XT is a unified box, and it is integrated with VVOL, our software-defined storage."
"On the Data Domain side, the most attractive feature is the compression ratio, which none of the other products in the market are currently able to provide. On the Unity side, what customers mostly like is the availability guarantee."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"The solution's initial setup process is easy."
"Its initial setup process is easy."
"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."
"Lenovo ThinkSystem DE Series is quite an elementary box, no frills. It does not have all the functionality of the DM but it is acceptable, it does its task. It integrates pretty well."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"The solution is very easy to set up."
 

Cons

"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."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"The UI for this solution needs to be improved."
"We need better data deduplication."
"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."
"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."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"​Improve the interface and provide more management capability."
"The Host LUN ID is sequential by access in the hosts. When one LUN needs access by many hosts (for cluster purposes), in some cases the Host LUN ID remains different on each host."
"This product needs to have better integration with enterprise backup solutions and archiving devices."
"If you compare it with VMAX, where we communicate with the box through Solutions Enabler and there are a lot of commands and a lot of flexibility, the command line for Unity needs to enhanced."
"The user interface could use improvement."
"We need to improve the controller to work as active-active. We also need to improve the snapshot on the Unity site."
"Scalability is not good. We have a Unity 300, now we have to do a data-in-place conversion for the next upgrade because only 150 slots are supported, not drives, only slots."
"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."
"Its performance could be faster."
"Improvements can be made to the product's performance."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"The product could support advanced software integrations."
"The solution could be more scalable, although it suits our present needs."
"There could be a snapshot feature in the solution."
"In the next release, I would like to see support for Hyper-converged infrastructure."
 

Pricing and Cost Advice

"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."
"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."
"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."
"As far as the licensing costs, everything is included in the license."
"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."
"Our licensing fees are $500,000+ USD."
"We bought extended warranties out of the box because our customer has a bad habit of managing warranties."
"It is an average priced solution."
"Pricing for this product is manageable, though slightly higher than comparable products."
"One of the most valuable features is its cost. It was inexpensive compared to other arrays that we were looking at."
"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."
"As far as licensing goes, I love how VMware works with Dell EMC Unity. It's great. They work hand in hand. They have made it so simple."
"I rate Dell Unity XT’s pricing a nine out of ten."
"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."
"The pricing is fair and low compared to other products in this category."
"The pricing for this solution is good compared to HP or Dell EMC."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."
"The best thing about this solution is its price, which reduces our costs."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"The solution's price could be better."
"We have a five-year contract for providing support."
