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.

Performance and interface improve data processing speeds but require complex configuration

The most valuable features of VMAX are its performance and GUI interface. We have seen significant improvements in technology over the last four to five years. The snap feature, along with deduplication, has notably enhanced our data processing speeds. We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution.

Quotes from Members

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

Pros

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

"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."

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

"The database workloads are pretty fast because I frequently move data from here to there."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."

More Everpure FlashArray X NVMe pros

"We are replacing legacy hardware and hardware that is going out of support, and we are consolidating two or three systems into one."

"Real Unified Storage (Block, File, VVols) in a unique 2U hardware."

"It is nice the way ESRS works with remote support, being able to remote in and take a look at problems proactively."

"It's unified, it does block and file, so that is pretty important to my customers who might have file servers around their environment. I can roll them all up into a single array, as well as provide block storage for them on one array."

"We use it to backup our storage, and also positioning LANs by using the file option, then the block, and it is very easy and convenient."

"Purchasing; We worked with a sales rep to purchase our Unity."

"We have resolved IT challenges with this solution. It sped up our environment. We went from spinning disk to all-flash, which reduced our footprint."

"The most valuable aspects of this solution are its stability, performance, and ease of updating."

More Dell Unity XT pros

"The product's initial setup phase was good."

"It works very well."

"The ransomware protection feature is housed in a separate unit, specifically addressing the top twenty most critical threats."

"We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution."

"The snapshot feature has been precious for our testing processes, application development, and managing testing environments due to its efficiency and ease of use."

"The most valuable features of VMAX are its performance and GUI interface."

Cons

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"They could add more support for file storage and different types of storage."

"I'd like to see the product implement active replication for vehicles such as VMware."

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"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."

"There is room for improvement in the pricing of the product."

More Everpure FlashArray X NVMe cons

"This product has some scalability issues. Before you can get support, you have to look for the service tag number on your product which could make it difficult to access support."

"The one thing that we would look at would be if they were to expand the file level features, just to give us a balance or a tier between it and Isilon options out there, for unstructured data."

"Firmware Upgrades in EMC Unity require you to manually download OS and Drive firmware, this should be integrated (Nimble does this). When you order an EMC Unity, you have to specify the block size. This is weird for me and even weirder that you cannot change this afterwards, you should be able to specify per LUN/datastore (Nimble does this as well)."

"I called about an issue where I couldn't get VVOLs registered. It turns out it is a bug in the code and that there is no information about when it will be fixed. It's just not going to work. I was a little miffed about that."

"Since Dell took over EMC, the support has been very bad. Before, the support was fine. Now, the support is slow or they don't react."

"My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint. We were trying to run some commands just to see how the storage snaps were interacting with the storage array, and it was a little difficult to look up exactly what commands should be run. The Help files detailing what exactly the commands did wasn't as detailed as we would have wanted them to be."

"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."

"We had one incident with a memory leak that led to controller reboot. Although it had no impact, when such things happens the storage should be more aware of it, send alerts, and propose corrective actions."

More Dell Unity XT cons

"The scalability of VMAX is somewhat limited, especially in terms of cache scalability. We've had to procure additional engines to address this limitation."

"Improvements are needed in both partition recovery and scalability."

"There is room for improvement in the centralized administration."

"We encountered some challenges during large data migrations that could be addressed for smoother transitions."

"The configuration part of the product is an area with certain shortcomings where improvements are required."

"The scalability of VMAX is somewhat limited, especially in terms of cache scalability."

Pricing and Cost Advice

"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."

"The support cost per array is about $20,000 a year for 24/7 support."

"With VMware, we pay $300,000 annually."

"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."

"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."

"The licensing is on a yearly basis."

"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 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."

More Everpure FlashArray X NVMe pricing and cost advice

"The solution is very expensive."

"The solution is extremely functional for the price that we pay for it. It is worth the investment."

"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."

"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."

"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."

"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."

"Most licenses for the solution are free but upgrades are available when adding additional software or storage."

"The solution’s pricing is competitive."

More Dell Unity XT pricing and cost advice

"It is not a cheap product."

"The price falls within the mid-range, neither inexpensive nor high-priced."
