Technical Lead at Wipro Limited
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.

Quotes from Members

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

Pros

"The solution is very reliable."
"Manageability is its most valuable feature; it is simplified storage, as we don't have to maintain or administer it on a daily basis, which is good, and we can depend on the solution's ability to phone home and leverage the built-in support function of the product."
"We were previously on legacy storage systems, and after moving to Pure Storage, our stability and performance both drastically improved."
"From the first test that we have conducted, we are very satisfied with this solution."
"Pure Storage FlashArray is a good product with minimal management requirements once set up correctly and helped reduce our storage footprint from EMC."
"Despite the overuse of buzzwords and re-classifications, the storage industry has actually seen dramatic improvements over the last 3-4 years."
"Pure Storage FlashArray's overall speed is its most valuable feature."
"It simplifies the overall management. We don't have to worry about storage anymore."
"We use GPFS Scale for parallel file access, the file management, and it's an essential part of our operations."
"The most valuable feature is the ability to share files across different platforms."
"We tested a complete site loss with the initial loss of the complete data center and the system was always up."
"It is incredibly scalable and stable."
"We use it for our data over multiple systems, and at the same time it is a shared file system that works pretty well for the most part."
"Spectrum Scale is one of the most important products in our environment now."
"The profile share is a valuable feature."
"I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system."
"This is an easy-to-use product for adding flexibility to your storage solution."
"The single management panel is the main feature that is wonderful for the customer."
"The most valuable features of the solution are that it is easy to deploy and the support is really good."
"The solution is simple to configure and provides good performance and less footprint."
"The technical support is awesome."
"The product is user-friendly from an administrative standpoint and very easy to use."
"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."
"VMware Software Defined Storage gives higher availability against data corruption."
 

Cons

"I would like to see additional features like performance monitoring, configuring alerts, and the customization of alert thresholds."
"The overall scalability for this product could be improved as well as having a single console to management multiple arrays."
"I would prefer that they lower their pricing."
"It would be beneficial to have a health check command that can be run from the CLI to ensure that all hardware components are functioning properly rather than having to enable remote access and connect to support for a health check."
"I would rate this a seven out of ten because it's a good performance storage, but the price is a little bit high."
"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"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."
"I have been primarily working with storage and have not fully explored other areas, but there is some room for improvement when it comes to performance reporting."
"The biggest problem is that it is not able to provide block storage."
"The main issue that we have now is with the encryption. They want to use more metrics in encryption, which is not working very well."
"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."
"It would be helpful if there was a graphical user interface that could walk you through the deployment process. The instructions surrounding setup aren't the best. They need to be more step-by-step."
"I believe there is no graphic user interface, so they should include it."
"Maybe it needs integration with HA."
"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."
"Making it a little easier to add bad file sets would help. There is a transition to how you add storage and how you add a file set, so making that a little smoother would probably be my recommendation."
"The solution has some limitations in terms of replication to remote sites or cloud infrastructure, which need improvement."
"It doesn't have the ability to be deployed on any kind of hardware and network connectors."
"VMware Software Defined Storage should include a shared database on a standard version."
"I'd like to see improved hardware compatibility"
"The performance is not as good as some competing products and reporting can be improved."
"It's easy to scale and expand but the main catch is the cost. It's expensive."
"Simplifying the licensing model and making it cheaper would improve the solution."
"The cost of the product is where an improvement could be made. It's generally very expensive and requires a lot of architecture that needs to be designed according to specific situations."
 

Pricing and Cost Advice

"The pricing is very attractive and it delivers performance for the money."
"The price is very reasonable when compared to other solutions."
"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."
"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"It could always be lower, but it's okay."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."
"We purchased a license to use this solution and we pay for the storage ourselves."
"The licensing is based on the number of terabytes."
"The solution is costly but reliable."
"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."
"VMware Software Defined Storage is a slightly expensive solution."
"The solution is very expensive."
"I believe there is a yearly licensing fee of around $2000 - $5000. I don't think there are additional costs above that but it depends on the type of infrastructure you're booting."
"The product is quite expensive and is among the most expensive for this type of solution."
"A single socket costs you around US $6,000 for three years. At a minimum, you have a three load cluster for a medium or enterprise-scale company. It can get quite expensive because you're likely to need four to six sockets on the other side. It comes to around $30,000."
