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.

Offers flexibility and top-notch technology

You can go to bed peacefully if you have a NetApp. If you have NetApp within your data center, you get to know about power failure if you are using it. Your NetApp will still come alive. Even if it does not come alive, I can say that it is not like other tools when it comes to dealing with power failure. The tool is affordable, and the technology is top-notch. It is the only technology that has software for what we call inline compression and deduplication. All the products under NetApp are aiming to use AI. I know that you can achieve whatever you want to do with NetApp EF-Series All Flash Arrays. I rate the tool a nine 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

"On a scale of one to ten, I rate Pure FlashArray as ten."

"What I really like about this program, is that it is easy to use and easy to configurate."

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

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

"The most valuable features of this solution are its ease of use and performance."

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

"One of the best features is the support, which is excellent."

More Pure FlashArray X NVMe pros

"To be programmatically administered is huge, it is one of the key features that we like about it."

"A lot of the Unisphere interfaces are greatly improved in terms of monitoring capabilities, alerting, and ease of use. Setting up the storage and the file system are all just a few clicks away."

"The valuable features of Unity include that it's flexible, has a friendly user-interface, and provides good performance."

"Dell EMC Unity XT has good integration with VMware."

"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."

"It has compression, which allows you to store more data than you would normally under the arrays."

"It is pretty stable. I like the stability, because everything works like it should. We made it all redundant. So, we don't have anything to worry about."

"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."

More Dell Unity XT pros

"The management of it is very simple. that is the most valuable feature."

"The main advantage of this solution is performance."

"I would have to say performance at this point, because the application it is based on is so diverse."

"The hardware and software of NetApp EF-Series All Flash Arrays are easy for us to use."

"The most valuable feature is the ability to set a specific margin of performance to a specific workload."

"It provides multi-protocol, which is what gives the edge when it comes to big lineage PC workloads."

"Compared to Dell Unity XT, what I see as an advantage in NetApp EF-Series All Flash Arrays is the fact that it is more scalable...The performance of the product is good."

"I like the performance aspect of EF Series. It basically provides everything that we are looking for as a solution, very low latency and very high performance."

More NetApp EF-Series All Flash Arrays pros

Cons

"I would like to see replication and DR features in the next release of this solution."

"Adding some functions to the product would be beneficial."

"The tool's pricing is higher than competitors."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

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

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"We would like to see VNC integration or be able to use Pure Storage with VNC."

"The software layer has to improve."

More Pure FlashArray X NVMe cons

"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."

"There is an ESRS problem that we're facing where, for some reason, the other Unity has not been able to register to EMC. The support information is not upgrading and nobody can tell me what is wrong with it. It's a minor issue, the ESRS is still working, but it is something that is very confusing and nobody seems to know what to do about it."

"Thick provisioning of LUNs."

"The NAS capabilities of Unity - I have to say there are a lot of things I miss. For example, deduplication for hybrid. I have tons of customers with VNX and dedupe. These customers achieve around 50% dedupe efficiency and they mostly use them for archive. If you're talking about 50TB of NAS, which is stored in a 25TB repository, which is very economical, and you can not provide that in a Unity hybrid box, you have problems."

"One of the issues we've had is that controllers have crashed several times... We've had a lot of problems with the storage processor, SPBs. We've actually had them crash."

"Currently, the protocol SNMP is not implemented. That's a problem, as we follow this protocol and I can't check the integrity of this equipment."

"There are features still to come, like compression and deduplication on hybrid platforms, VDM improvements to be developed for NAS environments, and also improvements in the “self-migration” tools to push or pool information (to assist the migrations to and mostly from third-party arrays)."

"The interface can be a little challenging for someone new."

More Dell Unity XT cons

"I’d like to see bigger, faster, better hardware, of course. I think that is the way the hardware is trending anyway; bigger, faster CPU, better software, fewer bugs, all that stuff. T"

"It was difficult to implement and lacks some additional features that would be useful, but as a solution fits a particular need for our organization."

"Things like the FlexClones, SnapVault, SnapMirror, all of that. Some of it's available on the EF series, but we like what we have in the FAS system."

"The initial setup phase of NetApp EF-Series All Flash Arrays is not straightforward and needs improvement."

"Their problems are on the software and the controlling of the storage where they lack segmentation and federation."

"There could be better integration with some of our Cisco products."

"We need a center related to NetApp in Egypt so that we can deal with them directly."

"The solution's technical support is not as good as it is supposed to be since you have to push them to get support."

More NetApp EF-Series All Flash Arrays cons

Pricing and Cost Advice

"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."

"We pay approximately $50,000 USD per year in licensing fees."

"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."

"The licensing is on a yearly basis."

"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."

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

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

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

More Pure FlashArray X NVMe pricing and cost advice

"It is shipped with all licensed, included for this product range, no need to buy additional licenses"

"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."

"The price of Dell Unity XT could improve. However, it is a one-time purchase."

"There is no capacity license for XT and no additional costs for expansions. I would rate its pricing as four out of five."

"We integrated it with VMware vSphere at no additional cost. As we moved into VMware vSphere, this is what we bought to go with it for our storage performance."

"Licensing is a little bit confusing. Going through everything with them, there are a lot of line items to go over. Every single thing is broken down into a line item, and it starts to get really confusing in terms of what we're actually purchasing when it comes to the product."

"The ROI is right where we need it to be. It's a reasonably priced array."

"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."

More Dell Unity XT pricing and cost advice

"Adding more capacity will increase the cost."

"They need to improve its pricing. The storage market is dying. So, they need to improve the price because it should reach all people. NetApp is one of the top ones, and they are charging a little bit of royalty as compared to other storage solutions."

"Cheaper pricing is always good. NetApp has been doing everything the right way. They've been figuring out things really well, going in the right direction."

"They provide licenses upon purchase, so there's no need for additional licenses. Regarding additional expenses apart from the standard licensing fees, such as for support or maintenance, there aren't any. Updates take around twenty to thirty minutes, including rebooting the systems, and we haven't faced any problems with the NetApp EF-Series All Flash Arrays. We utilize various other storages like Fujitsu, IBM, and Dalian SIP, but the NetApp EF-Series stands out as we've had no issues throughout the entire year of usage."

"The pricing of this solution is competitive with other vendors here in Egypt."

"NetApp EF-Series All Flash Arrays is an expensive product."

"One has to opt for a perpetual-based licensing model for one year or three years. After three years, you need to renew the license."

"It's a lot cheaper than what the other vendors have for the same type of environment. It saves us money."
