Chief Technology Officer at Lambda256

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.

Pre-Sales Manager at a tech services company with 51-200 employees

Offers better price and features compared to its competitors

The technical support for the solution is very good. Huawei, in our region, has more than 2,000 employees in the office, and they mostly have post-sales engineers for storage, servers, and networks. Huawei also trains its partner engineers on the storage it offers. If a customer faces any problem, then a partner engineer will first resolve it. If an issue is not resolved in the tool, then Huawei engineers get involved, and the case gets lodged with Huawei's tech team, after whom a Huawei engineer will come. The partner, a tech team, and then a Huawei engineer get involved in the support process. I rate the technical support an eight out of ten.

Quotes from Members

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

Pros

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

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

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

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

"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."

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

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

More Pure FlashArray X NVMe pros

"The Metro clustering and solid-state performance, are the most valuable features of this solution."

"Linear performance – The XtremIO wasn’t the fastest in all tests against other all flash arrays, but even with a massive workload, the response time and user experience were absolutely predictable with no sharp drop-offs."

"The initial setup is straightforward."

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

"A valuable feature of XtremIO is that, in terms of administration, it's simple and manageable."

"The most valuable features are: complete performance and ease of use."

"XtremIO’s capability to run any workload without much in the way of design considerations makes this very easy to use and size."

"We mostly use it for backup, because we cannot measure anything, and we are afraid to use it for surveillance systems. We were planning to use it for mostly for surveillance systems."

More Dell XtremIO pros

"It is easy to use, deploy, communicate and manage this solution."

"The initial setup was straightforward."

"Huawei OceanStor provides numerous features that are tailored to cater to the requirements of all types of companies."

"Stability: The product is designed to have always HA (High Availability) with redundant network and processors."

"The most valuable features of Huawei OceanStor are the dashboards, bandwidth, and data performance."

"It is easy to implement or install the tool."

"The solution is easy to scale as needed."

"If your virtual machine that resides on it completely fills the storage space, thanks to it's built-in function of all-zero data space reclamation, you just have to ask to System Engineer to run a zero-free on hosts (thin provisioned) and you will get more space instantaneously."

More Huawei OceanStor pros

Cons

"In the future, I would like to see integration with enterprise backup systems."

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

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

"We need better data deduplication."

"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."

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

"The software layer has to improve."

More Pure FlashArray X NVMe cons

"Dell's technical support could be better."

"I believe having more replication options comparatively to VMAX (other than RecoverPoint) would be great."

"The solution needs to be simplified. When you integrate your storage with other systems, could use a little bit of automation."

"Scalability is something that can be improved because there is an issue when it comes to mixing versions."

"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."

"The implementation isn't exactly complex, but the solution should have some enhancements in it to make the process more centralized."

"Get rid of the Java aspect of the GUI console."

"We've encountered challenges in integrating other products with Dell Xtremio, as it tends to be more vendor-locked. This means we can't easily explore other solutions that might work alongside Dell."

More Dell XtremIO cons

"Based on what we were quoted, the stated capacity was not a true reflection of the actual capacity."

"Technical support could be more helpful."

"A concern with OceanStor is pricing. However, apart from that, there are no significant limitations or technical issues."

"When it comes to the technical support team, I feel that the response time is an area with certain shortcomings where improvements are required."

"The technical support has been a let down for us. It's something the company has to work on. We haven't been satisfied with their level of service."

"Based on what we were quoted, the stated capacity was not a true reflection of the actual capacity. The data store ran out of space, and Huawei had to send a new unit."

"From a political perspective, there are issues selling Chinese brands to Western companies, as some may not be permitted to use them."

"The main concern is regarding the usability of the data storage."

More Huawei OceanStor cons

Pricing and Cost Advice

"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."

"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 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."

"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."

"Given its price, Pure is not the first option."

"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."

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

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

More Pure FlashArray X NVMe pricing and cost advice

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

"The price of the solution should be reduced. The price matches the price of a VMAX service but it does not have the capability of a VMAX service. However, the prices of Dell EMC XtremIO can be reduceable."

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

"Licensing is approximately $200,000 per year."

"You can get a two-year or three-year license for the tool. You can also opt for a perpetual-based licensing model, which can be renewed on a yearly or two-year basis."

"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."

"The initial purchase price was good but when you need to upgrade, it's a different story."

"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."

More Dell XtremIO pricing and cost advice

"Huawei OceanStor is priced very well but is a bit complicated."

"Its price is affordable."

"This product value matches its price."

"The pricing depends on the features the customer wants, such as storage, RAM, and processors, but in general, Huawei is much cheaper compared to Dell and Cisco."

"Overall, the solution's pricing was cheaper."

"The tool's pricing is competitive and affordable. It has the best possible pricing that we can get from Huawei. The prices are fixed and there are no additional costs."

"The product is cheap."

"It's roughly affordable."
