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.

Quotes from Members

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

Pros

"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."
"We were previously on legacy storage systems, and after moving to Pure Storage, our stability and performance both drastically improved."
"Our clients see a reduction in total cost of ownership by around 40%."
"Has also helped simplify storage for us. The other person we put in there, took about a week to implement. And we had both arrays set up within around four hours with a thirty minute drive time between the two locations."
"We have seen savings in our storage, and the speed of deployment has gone from several days to a few minutes, reducing backup and restore times from 93 days to minutes and simplifying storage for us."
"The console is simple to use. It has good performance. It is easy to install, understand, and manage, with a good ratio of deduplication and compression. It is doing its job."
"The most valuable feature is its upgradeability."
"The most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"Lenovo ThinkSystem DE Series is simple to use"
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"Lenovo ThinkSystem DE Series is cost-effective; there is no license, all of the features are bundled together, and you can renew the bundle with all of the features included."
"Lenovo ThinkSystem DE Series is quite an elementary box, no frills; it does not have all the functionality of the DM but it is acceptable, it does its task, and it integrates pretty well."
"Lenovo ThinkSystem DE Series is quite an elementary box, no frills. It does not have all the functionality of the DM but it is acceptable, it does its task. It integrates pretty well."
"All the features that we were sold and told about, they all work; it's been good."
"The most valuable features are the low latency and high-performance."
"The business copy solution has become faster using SnapMirror."
"The speed of data retrieval is the most valuable feature. We mostly use it for our SAP database and we are getting good IO from the hard drive."
"This solution makes everything a lot faster. The time to move data around, boot and migrate VMs is much faster."
"NetApp AFF is very good at cleaning up your storage."
"The Snapshot, SnapMirror, and SnapRestore functionalities."
"It has improved performance for our enterprise applications, data analytics, and VMs. These improvements are a result of all-flash, throughput, reliability, compression, etc."
 

Cons

"A three wave application or multi-wave application synchronization would be an improvement."
"We would like to integrate it more with our backup solutions."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"More cloud connectivity would enhance the solution."
"I would love for them to have a hyper-converged solution."
"CIFS and SMB Shares cannot be mounted directly."
"During heavy load situations with 100K IOPS on one specific port, it requires more granularity level for distribution."
"The cost of the storage needs improvement."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."
"The solution could be more scalable, although it suits our present needs."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"The product could support advanced software integrations."
"It is really entry-level. In the next release, I would like to see more functionality."
"Improvements can be made to the product's performance."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"Specifically, the current pricing bothers me; pricing is very high."
"It would be very useful if we could do the NFS to CIFS file transfer, but it is not supported at this time."
"Going forward, I would like more performance analytics on it, on the area itself, instead of using some other tool."
"We found NetApp support to be a mixed bag. Sometimes, it's real good; sometimes, it's real bad."
"Some of the applications have changed over the years. Their complexity was there before, but moving forward we've seen a few features being taken away in some of those applications, that we had grown to love."
"It would be nice to see a 1 GB portal for networking on the back rather than just the 10 GB that we can use as a backup."
"NetApp is a little more on the expensive side, so it'd just have to fit whatever that they're trying to do, whatever their company is."
"It used to give us the volume where LANs should be placed when we created a LAN in the older version. However, in the newer version of ONTAP, it does not give where to place the LAN in the volume."
 

Pricing and Cost Advice

"The pricing is very attractive and it delivers performance for the money."
"The pricing is an issue. However, being all-flash, it will always be sort of expensive."
"We lost a lot of customers because we couldn't compete on price with other vendors."
"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."
"There is always room for negotiation."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"The cost has room for improvement."
"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"The pricing is fair and low compared to other products in this category."
"We have a five-year contract for providing support."
"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."
"The pricing for this solution is good compared to HP or Dell EMC."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"The best thing about this solution is its price, which reduces our costs."
"The solution's price could be better."
"We have been able to utilize and leverage equipment which was purchased a decade ago up until this past year. So, we were running disk shells for 13 years and all we were doing was upgrading the filings and controllers, and using the same disk shells. Therefore, we were able to do something where we didn't have to invest that much. Recently, we had to upgrade all our disk shells, but it was a lot less because the technology had changed a lot since those times. It is faster now, and we have SSDs. We have larger drives that are 4TBs and 6TBs. Everything can condense so we are saving disk shell space and rack space. We are paying less now than we did at that time"
"I am comfortable with the pricing, which is fair compared to others."
"The price to performance ratio with NetApp is unmatched by any other vendor right now."
"The pricing is good."
"NetApp AFF is an expensive solution."
"The price of the upgrading of the solution is high. I could buy a whole unit of All Flash FAS 300 with a shelf for around $285,000. Yet if I want to add one additional shelf, it'll cost me $275,000. So they want you to upgrade by replacing it. It's cheaper to buy a whole new unit than to just scale out. The upside is they last. AFF lasts us three or four years. So that's a good investment."
"It's expensive but we think over time all the prices are going to go down."
"We don't like the cost. We would like to buy more."

NetApp vs. XtremIO
Is there another storage platform as feature rich as NetApp FAS? I think it is fair to say that NetApp FAS running Clustered Data ONTAP is a very feature rich platform – the move to the clustered version of ONTAP has brought many next-generation features including Scale-out and Non-disruptive…
