All-flash storage has unified my clients’ workloads and has reduced TCO through efficient data services

The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors. IBM, Lenovo, and Dell are more aggressive on prices. It is a very complicated market, especially now, and I understand the prices are higher at Everpure because of the software and all the enhancements it has. However, in this competitive market, we have a big problem selling to customers that are on a tight budget. A product with better pricing would be a win in the end. The RC or C20, for example, was a very good product that I could sell more easily than other options. Everpure FlashArray//C is sufficient for most workloads and virtualization workloads if you do not have very large databases. A product like that helps, and perhaps a new product in the future that is a little cheaper than the current options would be a possibility to gain more market share. I see the return on investment clearly from using Everpure FlashArray, but the challenge is selling it to customers for the first time. There are many customers who fall in the sweet spot where they are too small for an X or even a C model. They need something a little cheaper, they have the money for a cheaper version, and they need the performance of a Pure system. These customers could be more easily approached if Everpure offers a version of a local device in the future that is even cheaper than the C-class. I am trying now to help customers understand the concept behind AG1. I know that AG1 is not profitable if capacity is less than 50 terabytes. However, some customers would be very willing to pay for 25 terabytes in a cloud operated by Pure and to have it accessible with very good speed. We will see what the future brings.

A solution with a simple configuration and good stability but it's quite expensive

Access to technical support should be improved for our region. Technical support is good, but they're very hard to access. When we have a problem with this storage, it's usually related to a very bad configuration. All-Flash Storage is very, very expensive. They are important solutions so I don't really have any ideas about how to rectify this. The device could use better monitoring tools.

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.

Quotes from Members

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

Pros

"The Pure Storage customer service is by far the best part of the product and organization."

"The most valuable feature of Pure Storage FlashArray is the complete set of functions it provides."

"I am satisfied with this solution, and we plan to keep using this solution."

"After the implementation, the time to run the process was reduced to minutes and it did not require any manual intervention from our DBAs."

"It is easy to manage. You don't have to have the same people who used to manage the Dell EMC arrays because the solution is more intuitive."

"It overperforms both in terms of storage capacity and throughput, and bandwidth capability."

"The most valuable features of Pure Storage FlashArray are the management view of the solutions, ease of provision, and deprovision, it is fantastic."

"We currently have four Pure Storage FlashArray boxes, and all the storage boxes are on an Evergreen subscription model where we receive the latest hardware and features without any cost in a completely non-intrusive task."

More Everpure FlashArray pros

"Built-in snapshot support gives us SAN-side functionality most other platforms would have had us license separately."

"From my perspective, it is a huge success fulfilling everything we needed and more!"

"Our holdup was disk I/O, so we did a PoC with Kaminario and we reduced build times down to fifteen minutes for a full build from two hours."

"Ease of use: My installers - my administrators over the system - they love how easy and fast it is to install and spin up a LUN and get going."

"Go with it. I tell people all the time they need to take a serious look at it."

"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."

"Rocketing IOPS results in performance we don't have to fixate on, so we can instead focus efforts on other layers in the stack, knowing that our SAN layer is lightning fast, with capacity to spare."

"Improved performance by more than 50x on our application."

More Kaminario K2 [EOL] pros

"My advice is to try it, because I think DM Series is a scalable all-in-one system with unified block and file storage and cloud tiering."

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

"The price of this solution is good."

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

"We are satisfied with the stability."

"The servers are fast and affordable."

"In this solution, I like the option of clustering two storages together and that there can be HA availability."

"The Lenovo ThinkSystem DM Series is a stable storage system."

More Lenovo ThinkSystem DM Series pros

Cons

"It was a little costly. The price was ultimately higher than both of the other solutions that we evaluated. I'd say that's the only downside."

"I would like to see a Nagios monitoring plugin which watches the health and performance of the system. The only one available just checks volume capacity."

"I think the pricing for Pure Storage FlashArray is the major issue because all the great things come with the price, and a lot of customers simply are not willing to accept it."

"When creating a support case, visibility should be extended to others involved in assisting."

"We ran into some issues with the program at first and we had to work around those issues to fix our problems."

"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."

"I find the pricing of Everpure FlashArray to be quite high compared to other storage solutions; however, the reliability and features are commendable."

"A year ago they promised that they would be able to read through the database encryption with more metric and they have not delivered on that patch, which is significant because it gives us back so much more storage room. We want to be able to read through the encryption."

More Everpure FlashArray cons

"There are a few areas where the system could be improved. Examples would be that the system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."

"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."

"Replication and de-duplication could be better."

"I would like them to improve the look of the product’s external casing and shelves."

"A single pane of glass to monitor/manage multiple arrays would be helpful."

"I would like them to come down in price."

"I would like to see them work with Cisco, so it comes off the FIs, instead of having to go through my 10-gig network."

"I would love to see capacity on its DRAM. I know it's not cost effective for them to do it, but I think that it could be a big differentiator and was a big differentiator from the beginning."

More Kaminario K2 [EOL] cons

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

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

"This is an expensive solution."

"The Lenovo DM Series is an excellent storage product, but I think it isn't competitive with other companies like Dell EMC and IBM because IBM products are very cheap and have more features."

"In comparison with other similar solutions, I think this one is the most expensive."

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

"The solution needs a simpler licensing theme around the DM series."

"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."

More Lenovo ThinkSystem DM Series cons

Pricing and Cost Advice

"It is a cheaper solution."

"In the beginning, we saw that the price is not very good. When we made some compilations about the deduplication and the compression and what the equipment does, including the differentiation of upper management of the storage, the price was not so bad. However, in the beginning, the price was very difficult to justify."

"There is an annual or perpetual license required for this solution."

"Price per terabyte is substantially higher than their competition. We would like to see it drop."

"It's expensive, but you get what you pay for."

"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."

"The cost of Pure Storage is subjective and determined by your environment. Pure Storage tends to be more expensive than NetApp, but it is cheaper than EMC. Performance varies with data workload, making cost considerations complex."

"Pure is typically more expensive than everyone else. You get what you pay for, but I have lost deals to similar solutions because of pricing. They include everything, and that's another positive about Pure Storage. They aren't trying to nickel and dime their customers for different features. It is all included in one price. The license is by capacity, and the price depends on the capacity and the discount we're getting from the vendor. You get the SKU of the physical appliance, support, and maintenance, and that's it. You're licensed for whatever feature they offer. It is all rolled up into the price of the appliance."

More Everpure FlashArray pricing and cost advice

"Kaminario is very competitive on price. They also have a pay per TB model."

"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."

"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."

"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."

"Licensing is very straightforward. The cost was considerably lower than other products we looked at."

"The licensing is all-inclusive."

"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."

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

"The solution is highly-priced."

"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."
