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.

Has optimized performance using cluster deployment and distributed file access but needs better visibility into network dependencies
IBM Spectrum Scale being software-based storage allows users to utilize any hardware supported or defined by IBM without dependency on physical hardware provided by IBM. This is one of the features I appreciate most because if you have existing infrastructure at your site but don't want to reinvest in hardware, you can purchase IBM Spectrum Scale software and deploy it as software-defined storage. Users can comfortably access data from their host to the storage host without relying on new network setup when deploying GPFS as it uses the existing corporate network. However, high-speed ethernet network is required. By adding switches to the same network where client hosts reside and deploying GPFS storage array, any file system created on the storage cluster can grant export permissions determining which hosts can access specific file systems. These hosts can directly mount them as remote file systems. The process is simpler compared to defining IQN for providing access to client hosts. Creating a cluster for clients with virtual machines or physical Linux/Windows machines requires installing GPFS services on client nodes, which creates a client cluster. Access is defined on the storage cluster for the particular client cluster, allowing all hosts in that client cluster to mount file systems with granted permissions.

Managing mixed RAID workloads has improved data protection and delivers strong performance
VMware vSAN can be improved in certain areas. In cases involving our large data stores with large VMs, we experience some latency, not during normal operation, but during database backup operations. We observed latency due to buffer issues from the top-of-the-rack switches. These issues are mostly network-related because all storage data traffic travels through the network. I have recently used Nutanix, and I observed that Nutanix provides better performance than VMware vSAN due to its data locality features. VMware vSAN is now providing data locality, but we did not use that option. If VMware vSAN provides additional features in the next release, such as the VM balancing feature called DRS on the cluster that VMware previously had, it would be beneficial. With DRS, VMs can move easily from one node to another within the same cluster. Nutanix does not provide that flexibility. When placing a VM on a cluster in Nutanix, the placement uses a balancing component. After that, the VM remains on the same host. If any contention occurs on the CPU or memory side, the VM stays in place until contention happens. If issues occur, the VM migrates to another host while transferring all objects to the same host. This is how their data locality is maintained. When a VM moves to any host, it moves with all VM objects. VMware vSAN does not currently offer this option. If a VM moves to another host, it accesses the disk object through the network, which increases latency. VMware vSAN now offers an option to select data locality, but it does not function like Nutanix. This is why some latency remains. If VMware vSAN can improve this feature, it would be very helpful and VMware would regain its top position.

Quotes from Members

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

Pros

"Overall, Pure Storage FlashArray has never let us down in front of customers so far."
"My advice to others looking into using Everpure FlashArray is that it's a really good product, especially if your main purpose is to get high speed with more redundancy and reliability; then go for it."
"We saw a vast improvement when we switched over to using the Pure Storage model over the XtremIO."
"It's reduced our overhead management time on storage, since it is so simple to get in and just provision a volume, present it to the host, and then you are done."
"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."
"After installing Pure, the processes that would take 40 minutes to two hours to complete are now done in five minutes."
"From the first test that we have conducted, we are very satisfied with this solution."
"Scalability is one of the best features. You can quickly add more. You can swap out the drives with larger sizes, you can add more shelves. All of that is perfect - the whole concept of keeping it modular..."
"It is incredibly scalable; you can add more storage to it, add more file sets, and add it to more servers, making it a robust product that should be able to expand with us."
"I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system."
"Spectrum Scale is one of the most important products in our environment now."
"The high performance of the solution is its most valuable aspect; if you compare it to other storage solutions, it is much better."
"We can have multiple systems within the same file system."
"We use GPFS Scale for parallel file access, the file management, and it's an essential part of our operations."
"I rate this product ten out of ten."
"It has been pretty reliable throughout the years. As far as capacity is concerned, it can handle most heavy loads."
"For our VMUG group, I was trying to set up a lab, and I tried to go with the VSAN for storage purposes; it's a very rock solid product, very robust, and compared to the previous iterations it is very flexible and very strong now."
"We had a directive from the CIO to check out and play with VSAN and then to do storage cheaper and better than before, which we have achieved."
"The most valuable features are Erasure Coding, Deduplication and Compression, and the advancement in stretching regarding replication."
"The solution is very stable."
"The technical support has been great from VMware vSAN."
"If you have storage, separate servers, or any kind of traditional architecture you can convert it to FCI with vSAN, and it is a very simple and easy-to-use solution."
"I like this solution because policies (such as resiliency) are applied per virtual disk instead of applied on an entire volume."
"When we started using vSAN, the speed (performance) of the solution was dramatically higher than the speed of our production systems."
 

Cons

"I’d love to view the average, minimum and maximum performance in the reports (Analysis tab - Performance) but it is only graphics and you need to export data in CSV to find this information."
"I wish they could collaborate more with the other vendors internally, instead of us opening cases with Cisco, HPE, VMware, etc."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"The solution is not cheap."
"The higher education moves slowly. We are still looking forward to implementing the full list of existing features."
"A noticeable area for improvement is the support for object storage."
"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten. They do what they do well. It's not cheap but we it's for uses that we needed."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"Maybe it needs integration with HA."
"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."
"There is room for improvement in the web interface. There could be more information available, such as charts and graphs to monitor performance."
"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."
"We do have some issues where Spectrum Scale does not work as expected. We have seen our Spectrum Scale servers go down unexpectedly, but because we have a cluster, it does not take out the entire organization."
"We do have some issues where Spectrum Scale does not work as expected."
"The initial setup is complex, especially if trying to avoid erasure coding, as it requires more discs. Avoiding erasure coding can significantly increase costs."
"I believe there is no graphic user interface, so they should include it."
"The upgrading process could be simplified."
"In a future release, they can bring in the object storage capabilities to this solution. Currently, there is not any compatibility."
"It needs to allow for more customizations and individualization specific to each user. It needs to be more malleable and adjustable to changing requirements."
"I would like more integration with the hardware when it comes to disc types and supporting the newer types of storage."
"If the support could be provided more quickly, it would be very helpful."
"The only thing I can think of at this time is to improve the performance monitoring and performance visibility within the GUI."
"Integration could be better. It should be easier to integrate vSAN with the dashboard you have, with Google, and the others."
"Better options would be clustered nodes, or even cloud configuration. There is room for improvement in cloud configuration, we typically do web browsing for management."
 

Pricing and Cost Advice

"Price is about the only thing that's wrong with it. A little bit better pricing would be great."
"We have seen a reduction in total cost of ownership."
"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."
"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"The solution could be cheaper."
"I don't know the exact cost but it's around $1,000."
"The license for Pure Storage FlashArray includes the support and there are no additional payments that are needed. This is not an inexpensive solution, you need to understand the value of your data before you use a backup solution."
"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."
"The solution is costly but reliable."
"The licensing is based on the number of terabytes."
"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."
"The vSAN is somewhat expensive to license."
"The product's price has been increasing lately...VMware vSAN is expensive."
"With vSAN, we didn't find the market that competitive."
"It is not a subscription model. It is a purchase model, but it is very important that you also buy technical support from VMware. This is probably the only disadvantage of vSAN. It depends on the use case, but it can be very expensive."
"With the new pricing model, it's expensive for the customer."
"We pay a yearly licensing fee."
"The only problem I have with VMware is the price. It is a good product, but it is expensive."
"The vSAN licensing is not an inexpensive product. It does cost more than hypervisor."
