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.

Complicated deployment and poor support persist, affecting overall satisfaction

The deployment process of Lenovo ThinkSystem DM Series is very complicated compared to previous GUI systems. Many customers have lost data while configuring it, indicating a need for improvement. The after-sales service is also very poor. Furthermore, it does not offer basic features like deduplication, and the service is generally considered to be very bad.

Managing Director at GCET

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.

Pros

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

"The initial setup was extremely simple and straightforward."

"I appreciate the performance."

"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."

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

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

"The most valuable feature of this solution is its ease of use."

More Pure FlashArray X NVMe pros

"Last year, I did a DM Series installation with my colleague, and this installation was effortless because we had Lenovo support on the phone, so it was easy to get help if we had any problems."

"We are satisfied with the stability."

"The servers are fast and affordable."

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

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

"Scalable and stable storage array."

"One of the most valuable features of Lenovo ThinkSystem DM Series is the snapshot feature."

More Lenovo ThinkSystem DM Series pros

"Considering the cost, I find NetApp EF-Series All Flash Arrays to be the best storage available in the market."

"The most valuable feature of this solution is the performance of the database access."

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

"The benefits are better up-time, better response time."

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

"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.

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

More NetApp EF-Series All Flash Arrays pros

Cons

"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."

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

"We need better data deduplication."

"There are some challenges with data encryption and reduction."

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

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

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

"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."

More Pure FlashArray X NVMe cons

"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."

"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."

"The solution should change the licensing model and allow customers to choose features based on their requirements."

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

"It takes a very long time to enter the management console, as well as to restart the system, and these are things that should be improved."

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

"This is an expensive solution."

More Lenovo ThinkSystem DM Series cons

"The price of the All Flash solution is very high."

"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."

"The only major drawback is the replication between EF-Series units."

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

"We have used IBM previously. We found that the storage from IBM was poor and we chose NetApp EF-Series All Flash Arrays because it can scale very easily."

"They could improve overall scalability through performance. Denser capacity, which is doable, it is what the competition is doing."

"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."

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

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."

"The licensing is on a yearly basis."

"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."

"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 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."

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

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

More Pure FlashArray X NVMe pricing and cost advice

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

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

"The solution is highly-priced."

"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."

"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."

"The pricing is comparable with other competitors and similar in mid-range solutions, and for high range solutions, it would depend on our requirements or needs."

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

"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."

"The price point for EF is considerably lower than the alternatives."

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