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

"The solution is very straightforward to set up."
"Technical support has been helpful and responsive."
"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's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"I appreciate the performance."
"The solution is scalable."
"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."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"The technical support is very professional and provides quick responses."
"Performance is a top feature."
"We've never had an issue with storage."
"The benefits are the simplicity, flexibility and the ease of integration between the Unity platform and VMware, for example, and Microsoft platforms; the integration tools and the simplicity of management."
"The replication is big for us. We use file services on Unity and it has a really nice file services interface. It's also easy to manage. It's really easy in terms of provisioning, replication. There are no real tricks to it. It's just easy."
"I think Dell Unity XT is one of the best options on the market at the moment, although there is some good competition."
"Via a click, we can deploy a data store or LUN to the ESX host. We can also deploy VVOLs to the ESX server."
"We have simplified it down to where we're using one storage pool inside the Unity, whereas on the VNX, we had multiple storage pools. This has simplified that aspect for us. It would depend on each organization. We're heavy into VMware and this ties into it so simply. It's made it a lot easier for us. I create a datastore inside Unity, it just shows up in VMware. I love that tie-in."
"Integration with VMware"
"Multi-tiering, positively affects the efficiency of the storage space."
"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."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"It is very stable even during multiple power failures."
"The replication feature provides another functionality to protect your data."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
 

Cons

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
"In terms of what needs improvement, the dashboard and management could be simplified."
"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"It is on the expensive side."
"In the future, I would like to see integration with enterprise backup systems."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"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."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"Replication with VMware - it's called the vSphere Metro Storage Cluster - is lacking in the Unity and is present in Compellent."
"Our request to Dell EMC for improvement was in the reporting and monitoring areas. Dell EMC built up a cloud ID so that we could see the overall storage numbers. We needed to have the proper KPIs to be able to see and manage things."
"We've got massive issues at the moment with IBM AIX. It's not stable. We have a lot of disk errors, production crashes sometimes."
"It isn't easy to find trusted partners for the product. The solution has issues with mid-level storage and does not come with enterprise storage."
"Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out."
"We had some issues recently because of a bug in the system. We were presenting LANs to the Unity array but I think it caused a disruption to the host. EMC did acknowledge it and provided an alternative way to do it."
"I haven't seen the roadmap for this solution."
"The solution should include a free process in the HPE portal that uses serial numbers to verify that hardware is genuine."
"VNX can improve by offering flexible upgrade options. It's not possible to add a single HDD to a current array and there are fixed rules to make upgrades."
"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."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"The CLI could be better documented, like with VMAX."
"Poor connection to FC."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
 

Pricing and Cost Advice

"As far as the licensing costs, everything is included in the license."
"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."
"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."
"The support cost per array is about $20,000 a year for 24/7 support."
"The product is expensive."
"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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"Given its price, Pure is not the first option."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"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."
"Our CAPEX was close to $42,000 and operating costs are below $1000."
"From a pricing perspective, this solution is comparable to others on the market."
"This solution is a good price for what you get."
"When I see other products—like HP, Huawei, and Lenovo—from competitors, I have seen a lot of disadvantages with EMC, price-wise. Huawei and Lenovo are very price competitive. Looking at the price point for a country like Sri Lanka, where we have a very low economy, I think you need to look at a pricing mechanism that is a bit more flexible."
"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."
"While Dell EMC is costly, I don't have any complaints about their licensing model."
"​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."
"The initial pricing and licensing are reasonable. Yearly EMC is more expensive."
"Pricing is somewhat higher, especially in Zambia, perhaps due to the low sales volume."
"The initial pricing and licensing are reasonable, the yearly EMC is more expensive"
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
"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 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.
