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.

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

"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."

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

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

"The latency is good."

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

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

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

More Pure FlashArray X NVMe pros

"We are satisfied with the stability."

"The price of this solution is good."

"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."

"The value we derive from using it is greater than other alternatives like HPE and Dell."

"The product’s quality of service guarantees the performance of each workload."

"The servers are fast and affordable."

"The FlexClone feature is the solution's most valuable aspect."

"Ability to cluster two storages together with HA availability."

More Lenovo ThinkSystem DM Series pros

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

"It is a very stable solution. Stability-wise, I rate the solution a ten out of ten."

"Its performance is most valuable. This solution is much faster than other as well as older storage solutions. The performance of the system is very good. We are getting 50 times better experience than the older storages. We are using AFF 300. It also has native cloud integration and most of the features."

"This storage solution is both stable and scalable, and it works for our needs."

"The NetApp EF-Series gave our organization easy access to our data bases."

"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."

Cons

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

"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."

"The software layer has to improve."

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

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"We need better data deduplication."

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

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

More Pure FlashArray X NVMe cons

"The solution needs a simpler licensing theme around the DM series. The problem is if you only need one of the features, you still have to buy the whole thing. The licensing needs to be more granular or flexible so you have the option to only license FlexCone or Inline Compression features."

"The licensing model needs to be revisited. It needs to be simplified."

"Lenovo ThinkSystem DM Series is not stable. If I have sold fifty boxes, about fifty percent of them experienced failure."

"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."

"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."

"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."

"There might be improvements needed in drive throughput as disk speed has been a limitation on Windows servers."

"Lenovo could have a wider variety of storage solutions in the NAS space."

More Lenovo ThinkSystem DM Series cons

"The pricing could be cheaper and it should have documentation in more languages, specifically, Russian."

"I would like to see higher-capacity drives, as they come out; I have heard that 15 TB are out on a different NetApp series. Getting those on the EFs would be nice."

"I've observed an issue when creating a new storage solution with NetApp EF-Series All Flash Arrays."

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

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

"Better support technicians for CAPP."

"This solution does not have any compression or deduplication."

"A little more manageability, a simpler management interface. It's not necessarily that it's way overly complex. It's just that it's not as easy as the FAS series."

More NetApp EF-Series All Flash Arrays cons

Pricing and Cost Advice

"As far as the licensing costs, everything is included in the license."

"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."

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

"The licensing is on a yearly basis."

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

"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."

"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."

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

More Pure FlashArray X NVMe pricing and cost advice

"The price of the Lenovo ThinkSystem DM Series is good."

"Lenovo offers two software tiers for the DM Series: basic and premium. If you need more features like the MetroCluster, you must buy the premium version. You can stick to the basic software if you don't need MetroCluster or features like asynchronous replication. That makes DM Series a little cheaper."

"The solution is highly-priced."

"The solution's pricing is similar to Dell and HPE."

"This solution is not available to many users because the cost is very expensive."

"Most of my customers pay for the license on a yearly basis. It can be expensive depending on the capacity number."

"he price point that we're getting is very competitive in the market. Since we are buying in such a large quantity, they gave us a huge discount."

"Price-wise, NetApp EF-Series All Flash Arrays is costlier than Dell. You have to buy a lot of licenses separately."

"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."

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

"The cost of our license is approximately $200,000 over three years for NetApp EF-Series All Flash Arrays. There can be additional costs for storage. For example, if you want to have eight terabytes."

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