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.

Ease of implementation and robust performance enhance multi-OEM support experience
We are limited only to hardware replacement, not administration tasks. We work on AMC products through Annual Maintenance Contracts. We provide support up to the 680 model. The XT680F is a newer model, and we support from 380F to 680F. The FlashSystem 8000 series is all-flash, and there is also a 5000 series flash model. We can compare IBM DS series, including the 8000 series for recommendations. For NetApp, we can recommend the FAS 8000 series.

Quotes from Members

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

Pros

"Pure Storage technology allowed us to automate tasks, reducing something which started as a 12-hour turnaround down to about 15 minutes."
"You can even review the devices from your phone. You don't need to be connected to your company's website or VPN to access alerts and reports. While you can't manage the devices using your phone, you can review all the important details about the machine."
"The reliability is very good."
"As soon as we introduced our first Pure Storage FlashArray, the first benefit was at least twice the performance increase. Our production databases simply ran twice as fast with no other change."
"We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray."
"Data deduplication is one feature I found to be the most valuable in the tool...Stability-wise, I rate the solution a ten out of ten."
"Once it's set up, it just runs on its own and only requires the occasional checkup."
"FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."
"Moving also from a hybrid to an all-flash array helped us to minimize footprints in our data centers."
"Pricing is relatively good compared to other vendors with the same specifications."
"We hear from our customers that it is stable."
"It gives me the flexibility with its ability to replicate to itself and the ability to use the Dell EMC Cloud as an option. That's always sitting there and waiting if we need it."
"The most valuable features of Dell Unity XT are the data compression for all of our VMs up to four times and the performance is good."
"This is a very stable platform, so far zero issues."
"I like that the solution is scalable. The initial setup is not complex. The basic licenses and software are included in the package. he primary advantage is that this product has been thoroughly tested and proven over time. I recommend this product."
"I like that when you log in it gives you a dashboard of what your storage looks like."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"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."
"The solution's initial setup process is easy."
"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"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."
"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"Its initial setup process is easy."
 

Cons

"Improved reporting on the deduplication and compression functionality would be beneficial."
"Awareness about Pure Storage needs to increase. Currently, people mostly think of Dell and NetApp when it comes to storage."
"In the next release, I would like to see file-level encryption."
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"The price of the solution can improve."
"They can also include file services such as NAS shares and CIFS shares. There should be provisioning of the file shares from a unified array."
"I think replication is one area that still needs improvement. Earlier, Pure Storage FlashArray only had IP-based replication. There was no API-based replication, but they have enhanced the feature now. However, they need to work on API replication for C-type of arrays."
"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."
"We'd like to see a cheaper version of an all-flash array in that footprint."
"I don't know where the hybrid cloud might be going or what connectivity there is between what was recently released as far as AWS and being able to manage both of them. Maybe there is an on-prem and an AWS instance in the same window, like a single pane, but I would like to see something along those lines, where there wouldn't be two locations to manage storage."
"As the solution continues to grow and gain more traction, things will come up that will just continue to deepen the integration between VMware, vCenter, and all those other components. Anything in the divisibility there and additional tools is always great."
"If there's anything Dell EMC could do to get the same performance for a cheaper price, that would be great."
"What we noticed was that the SP utilization is quite high, although the main load is on a VMAX."
"There are some features in VNX that I wish were in the Unity. For example, Storage Groups for isolating LANs and hosts. That is a big issue."
"It could always use native replication. Then I could get rid of RecoverPoint."
"We would like an AI feature that would protect the backup and minimize the consumed space so we can maintain the quality of the backup. This would help us minimize our IT cost in terms of the backup procedures."
"It would be useful to have structured solutions replicated to other sites."
"It is really entry-level. In the next release, I would like to see more functionality."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"The solution could be more scalable, although it suits our present needs."
"Its performance could be faster."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"The solution could be more scalable, although it suits our present needs."
"Improvements can be made to the product's performance."
 

Pricing and Cost Advice

"The price, in general, is around $100,000, however, I know it costs more."
"We have seen a reduction in TCO."
"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."
"The cost has room for improvement."
"When I last looked, the prices were reasonable, and we could get an excellent array for about $60,000."
"There are no licensing fees or other costs."
"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."
"You get what you pay for. It is expensive, but it really works."
"At the end of the day, the licensing cost is key, because every customer has a pain point, that the cost of each piece is high. So if they would bundle everything in a package, that is how the competitors are selling their footprint."
"Licensing is fine. We worked with a sales rep to purchase our Unity."
"We checked both HP and Dell and we determined that Dell EMC was a better option."
"We integrated it with VMware vSphere at no additional cost. As we moved into VMware vSphere, this is what we bought to go with it for our storage performance."
"The solution is extremely functional for the price that we pay for it. It is worth the investment."
"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"Go with the virtual appliance versus the hardware."
"The solution's price could be better."
"It is an expensive solution."
"The best thing about this solution is its price, which reduces our costs."
"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 pricing is fair and low compared to other products in this category."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"We have a five-year contract for providing support."
