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.

The Nimble CS-Series has proven to be reliable with 100% uptime
When we started the process of looking for a SAN vendor I had four primary criteria: reliability, performance, cost, and simplicity. We were really looking for a unicorn and were fully expected to have to make compromises in one of those areas. The Nimble CS-Series was recommended by our solutions provider, and we were blown away. Not only was it the most affordable option, but it was the easiest to deploy, had the best performance, and has proven to be reliable with 100% uptime.

Quotes from Members

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

Pros

"Everything works well, and it is very fast."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"Using this solution has benefitted us operationally by making us more efficient."
"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 high availability of the product is the most valuable feature."
"The most valuable feature of this solution is its ease of use."
"I appreciate the performance."
"The solution is very straightforward to set up."
"It's a great product if you want something that just works, and works fairly well."
"I don't think I've ever seen latencies above 10 milliseconds unless it was something that wasn't the array that was messing up. The thing is rock-solid."
"It will certainly help us scale bigger. If I look at the footprint, the VNX's was multi-rack. Now, all of a sudden, we're only at a portion of a rack. And, obviously, if we can scale within the same rack - we can certainly see that by the number of hard drives we've had to put in - we can scale a lot more easily."
"EMC is known for its reliability This product is good It is easy to install and maintain It operates with low maintenance and manpower costs"
"After migration to Unity 300F, we were able to put more DBs on flash, reducing latency, and the results were visible in the front-end systems, as all users noticed the improvement and productivity increased because users were able to perform more in the same amount of time."
"Dell EMC Unity XT has good integration with VMware."
"It has good performance."
"We're able to access it from just about anywhere, as long as we have access to a browser. That feature is really neat because sometimes we will go to a different data center or a different site, and if we need to access it to see a LUN or to see any type of storage, we can do that. That's one of the big takeaways with Unity."
"Since implementing VNX, we achieved a 10 times increase in the performance for its end users."
"The most valuable feature is the tight VMware integration, due to the migration from bare metal to virtualized environments and then on to the cloud."
"VNX 5200 works well with a medium VMware cluster, has good performance, and enables hardware disk replication."
"One thing I would like to explicitly mention here is the EMC support; it is by far one of the best supports you will ever get in comparison with any vendor."
"It is very stable even during multiple power failures."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"I think it's a good solution; it has many benefits and features that are of interest for many customers."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
 

Cons

"In terms of what needs improvement, the dashboard and management could be simplified."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"I would like to see replication and DR features in the next release of this solution."
"One area that I haven't been sold on yet is the POD replication."
"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."
"Maybe the price can be reduced since the solution is very 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."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"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."
"The lack of deduplication reduces some of the competitiveness compared to other products."
"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."
"I would like to see more compression and deduplication added to the solution. Today, our compression is about 2:1 and other solutions give us about 4:1 or 5:1."
"We'd like to see a cheaper version of an all-flash array in that footprint."
"If the product could only send alert notification via SMS, it would be much better."
"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."
"Dell EMC Unity XT has some scalability issues which they need to address."
"So far we haven't had many issues with the VNX. However, the Data Mover (that manages CIFS/NFS) part needs some improvements."
"Due to very complex structure and sophisticated architecture, it needs experts for trivial troubleshooting also."
"There were scalability issues, the scalability options are limited due to supported SSD."
"It would be very helpful to get an automated report that shows you the size of the checkpoints and get warnings when a checkpoint is reaching either maximum capacity per a file system or hitting the ceiling on the SavVol pool consumption."
"There is an easy replication process between distinct data centers via VPLEX and/or RPA. But I hope in the future that EMC/Dell could replicate this with other types of storage."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"The management software used for the VNX is Unicenter. While it is an improvement over Navicenter, used in older EMC SANs, it still feels outdated in comparison to other SAN management software."
"You need a lot of licenses in order to use this product, which makes the product expensive; the maintenance contract price also increases significantly every year."
 

Pricing and Cost Advice

"With VMware, we pay $300,000 annually."
"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."
"Given its price, Pure is not the first option."
"The licensing is on a yearly basis."
"As far as the licensing costs, everything is included in the license."
"We pay approximately $50,000 USD per year in licensing fees."
"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."
"While it has a good price to start, they could always make it cheaper."
"We purchased a five-year warranty."
"Go with the virtual appliance versus the hardware."
"The solution is very expensive."
"Obtaining a warranty is easy."
"One of the most valuable features is its cost. It was inexpensive compared to other arrays that we were looking at."
"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."
"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."
"​Reducing dependency on JavaServer Pages​ (JSP) could improve the administrative overhead.​"
"While EMC tends to be on the expensive side, the stability and support of their products are top-notch and I feel are worth the cost."
"Pricing is somewhat higher, especially in Zambia, perhaps due to the low sales volume."
"Make sure you understand how the licensing works and that you are getting the right set of licenses if you need array-to-array replication."
"The initial pricing and licensing are reasonable, the yearly EMC is more expensive"
"The initial pricing and licensing are reasonable. Yearly EMC is more expensive."
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."

The VNX range is older and is being phased out. I think you mean VNX 5200? That said the Unity 400 is the better investment as it is newer, cheaper to support, faster, and with higher capacity and bigger supported file system size.
