Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades
The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

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

"We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years. It simplifies storage for us."
"Pure gives us better compression, it's easier to manage, a lot less hands-on."
"The predictive performance analytics is a very good feature, as our system is performing better than before."
"The connections are a lot faster than what we had in the past. One InfiniBand does what we did on all of our Fibre Channels."
"You can get your storage access within two minutes, which is great, because it is a lot quicker for our team to get the servers up and running."
"It is pretty much just plug and play. There is not that much to do with it. It is very easy to use."
"We chose Pure Storage because it had the best performance of all the products that we tested."
"We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray."
"The most valuable aspect is the use of solid-state storage drives instead of spinning drives."
"The K2 has basically removed storage as a bottleneck in our datacenter."
"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."
"Technical support is absolutely great."
"The speed and, for us in particular in what we're doing, the data de-duplication."
"From my perspective, it is a huge success fulfilling everything we needed and more!"
"Implementation of the solution is very simple."
"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."
"We are satisfied with the stability."
"The solution offers very good reliable systems and storage for our clients."
"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."
"Scalable and stable storage array."
"Ability to cluster two storages together with HA availability."
"The product’s quality of service guarantees the performance of each workload."
"The Lenovo ThinkSystem DM Series is a stable storage system."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
 

Cons

"The price of this solution is high and should be lowered."
"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."
"In terms of improvement, Everpure FlashArray could have more attractive UI/UX design compared to other solutions."
"It needs to improve its price."
"They are doing some stuff with containers and an object search. These could be improved, because containers is one of the main topics that we are talking with our customers about."
"The GUI could improve, it could be more intuitive. There is hidden functionality."
"It would be nice to have a better view of the allocated capacity on their Platform as a Service solution because we have to do some manual calculations to understand how much we are going to pay every month to use the storage that is allocated."
"The solution needs an integrated NAS platform, file platform."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"I think it should have better performance with small files. With big data, its performance is top notch, but it is difficult to load small files."
"On the road map, I'm hoping to see Active Directory integration. Right now, you still have to use a local admin account to log in and manage everything."
"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."
"There are some mid-market SMB customers that it may not fit the best for from a pricing perspective, but for the vast majority of our customers, once we aware of it and learned about the technology which it performed with, it fits a very useful metric."
"The management graphical interface needs more improvement."
"The front panel of the drive shelf doesn't always seat firmly."
"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."
"There might be improvements needed in drive throughput as disk speed has been a limitation on Windows servers."
"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."
"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."
"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."
"In comparison with other similar solutions, I think this one is the most expensive."
"Lenovo ThinkSystem DM Series is not stable. If I have sold fifty boxes, about fifty percent of them experienced failure."
"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."
"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."
 

Pricing and Cost Advice

"I'm good with the licensing. Of course, pricing can always be less... It's actually not a bad pricing model, considering I don't have to rip-and-replace."
"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."
"The price is very reasonable when compared to other solutions."
"It is cheaper than NetApp."
"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"There is always room for negotiation."
"They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good."
"Pure has been flexible with us on the pricing models."
"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."
"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."
"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."
"The solution's pricing is similar to Dell and HPE."
"The solution is highly-priced."
"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."
