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.

Efficient and straightforward setup boosts data management capabilities

Scalability is a significant feature of Dell XtremIO, as it is easy to expand and manage. It provides a lot of features suited for complex systems, such as scalability and the ability to define multi-domain systems, which are beneficial for data management and storage separation. It is efficient from the customer's point of view, offering deduplication at both the volume and file levels. The configuration and setup are straightforward, provided one has knowledge in setting up network infrastructure like VLANs. It is easy to install, use, and configure, making it a reliable product.

Quotes from Members

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

Pros

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"Overall stability is very good. It is a very stable solution."

"Everything, especially the VMs inside, is pretty fast."

"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."

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

"The initial setup was extremely simple and straightforward."

"The solution uses newer technology for deduplication and compression."

"The latency is good."

More Pure FlashArray X NVMe pros

"Snapshots are valuable because of their seamless nature, as well as the minimal space each snapshot takes."

"The speed and scalability of Dell XtremIO are significant features that improve data storage management."

"The solution's most valuable feature is its high performance."

"Xtrem10's features are more simple to implement. The integration and interface are also good."

"Initially, we faced numerous issues with our analytical systems. However, we saw performance improvement after the implementation of the solution."

"The most valuable feature of Dell EMC XtremIO is the data protection (DP) group, it is one of the most advanced features in these types of arrays. The dedupe and compression that this array provides both do a superb job."

"Performance and deduplication. This is a very robust block storage option that offers both performance and data optimization."

"The most valuable feature of the solution is its performance."

More Dell XtremIO pros

"The implementation is not that complex for someone who has experience."

"Has very good deduplication and encryption features."

"The most valuable feature of HPE StoreOnce is the virtual drive."

"The product’s data retention is very good."

"The solution is stable."

"Quick recovery."

"I think StoreOnce's deduplication technology is crucial for cost efficiency and faster recovery, especially for backup and data protection purposes."

"It results in more efficient storage utilization, cutting capital expenditure in half."

More HPE StoreOnce pros

Cons

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

"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."

"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."

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

"The tool's portfolio is minimal. It is expensive."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"It is on the expensive side."

More Pure FlashArray X NVMe cons

"I would like to see more scalability."

"It can be more cost-efficient."

"In some cases where we don’t need the flexibility of the virtualization layer, we could free up resources on the VPLEX by using the storage replication."

"This solution is geared toward enterprise-level companies. Small and medium-sized businesses would find it extremely expensive."

"The solution's stability has certain shortcomings where improvements are needed."

"Native data replication: To replicate data between XtremIO devices, you need to use EMC’s RecoverPoint appliances to move the data."

"The product is highly expensive. Additionally, there is a significant lack of training, support documents, and forums available for Dell XtremIO, making troubleshooting difficult for third-party individuals."

"I would like hardware capacity additions to be a little more flexible. The upgrade path for the existing XTremIO units requires you to purchase 2 XBricks at a time and they need to be the same capacity as the existing XBricks."

More Dell XtremIO cons

"HPE StoreOnce Backup to Disk (BTD) is not a good backup solution for NAS devices. It does not have a dual controller, so if one controller fails, the entire system will go down."

"The appliance doesn't have the global deduplication, it has StoreOnce deduplication. It does not deduplicate across the appliance, it will deduplicate in one particular store. With the global deduplication, I could store more data."

"I would like to see better integration with Veeam software."

"The solution would be improved if it could also be used as a data store for VMware."

"The user interface of HPE StoreOnce is an area of concern where improvements are required."

"When it comes to upgrading, it always goes block-wise. One block is 48 TB raw capacity. It would be good if they can include a smaller capacity for SMB customers. Currently, it is not possible to increase in a smaller capacity. You have to buy the exact same unit. It would be great if they can provide a smaller next block. There are around 20 hard disks, and it would be really helpful if we can add 10 hard disks initially and 10 hard disks later."

"The platform's price could be lower."

"This product would be improved with the inclusion of more features to security or WORM."

More HPE StoreOnce cons

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."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"The product is expensive."

"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 licensing is on a yearly basis."

"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."

"Our licensing fees are $500,000+ USD."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"It is great when a product can deliver high-end performance capabilities while offering a very competitive price point."

"Don’t buy this array. You’re paying for loads of magic beans, since it’s mediocre at best for a platform in a rapidly growing field. Look instead at Pure Storage or something with variable block deduplication. You’ll end up spending less and getting a better product with actual support."

"It is expensive if you need to increase scalability."

"It is costly but worth it."

"With some workloads that benefit from compression and deduplication, costs are actually better than some tier 2 subsystems (while latency remains <1ms)."

"Too high priced for the Brazil market."

"XtremIO is an all-flash array, which means it's a costly solution. When compared with general mid-range storage solutions, this is more expensive. As far as I know, there are no additional costs besides the license."

"The license for XtremIO is in the box, so you don't have to buy anything."

More Dell XtremIO pricing and cost advice

"The product's pricing is medium."

"The product is not expensive. It is available at a good price."

"The licensing costs is capacity-based and come bundled with support."

"HPE StoreOnce is cheaper compared to other solutions in the market."

"The solution's cost is above average."

"The price of the product is reasonable."

"There are costs for additional storage and space."

"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."
