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

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"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."
"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."
"The latency is good."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"I appreciate the performance."
"Technical support has been helpful and responsive."
"The most valuable feature of this solution is reliability."
"The most valuable features include snapshots, Thin Clones, and deduplication and compression."
"The fact that it's hybrid is the most valuable feature. We have the SSD so we put our SharePoint on there and some of the stuff that requires a little more speed. For SharePoint, we want the pages to respond a little more quickly. And it's nice to be able to use the slower storage for stuff that we don't need as quickly, like file servers."
"This solution makes it easy to manage storage, provision new workloads, and scale-up."
"It has reduced the latency in application and database reads and writes... All-flash, it's fast. We have the 650 model which is all-flash, upgraded from VNX. It just flies."
"I like the easy management with the new Unisphere management and the HTML5 interface."
"The hardware itself, it differs from Compellent and differs from the VNX before it. It doesn't have a separate file harbor that goes with it, there are no separate NAS heads. It's 2U, you have file and block storage, so you get a quite a lot of services for a small footprint."
"It's easy for us to use because we use other solutions which are built for Unity, like VMware, which are recovery points. They work with the Dell EMC Unity system, as these products integrate well in our environment."
"The multiprotocol support. It's supporting NFS, fiber channel, CIFS, and these kinds of things. The multiprotocol is very attractive."
"The solution's initial setup process is easy."
"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."
"Its initial setup process is easy."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
 

Cons

"I would like to see replication and DR features in the next release of this solution."
"Maybe the price can be reduced since the solution is very expensive."
"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."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"In the future, I would like to see integration with enterprise backup systems."
"There is room for improvement in the pricing of the product."
"Adding some functions to the product would be beneficial."
"The UI for this solution needs to be improved."
"They should update to the cloud."
"I would like them to continue to build on the solution and expand on the functionality, like replication."
"I would like better integration with RecoverPoint. My major issue with the solution, all around, has been RecoverPoint more than Unity. While I like the easy user interface, I would like some more advanced features for troubleshooting built into the product, so that we can do more in-depth problem-solving."
"We are running VMware, and with the VNXe it was possible to restore. We're using Veeam for VMware backups and with the predecessor, it was possible to mount a backup or restore a backup from a storage snapshot. With the Unity 300, this is not possible."
"It is expensive, and the pricing could be better."
"I would like to see a more seamless virtual box integration with the physical box which can replicate, because the setup of the replication is very difficult right now."
"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 is a tier-three solution and it gives us what we need for archiving and backups."
"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."
"The solution could be more scalable, although it suits our present needs."
"It would be useful to have structured solutions replicated to other sites."
"The product could support advanced software integrations."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"Its performance could be faster."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
 

Pricing and Cost Advice

"Given its price, Pure is not the first option."
"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."
"Our licensing fees are $500,000+ USD."
"The support cost per array is about $20,000 a year for 24/7 support."
"The product is expensive."
"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."
"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."
"Licensing is fine. We worked with a sales rep to purchase our Unity."
"What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"Our CAPEX was close to $42,000 and operating costs are below $1000."
"There is not a license required for the use of the solution. We purchased a maintenance contract."
"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."
"The solution is extremely functional for the price that we pay for it. It is worth the investment."
"The solution should be cheaper."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"The solution's price could be better."
"The pricing is fair and low compared to other products in this category."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"The pricing for this solution is good compared to HP or Dell EMC."
"We have a five-year contract for providing support."
"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."
"It is an expensive solution."
