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.

Account Technology Specialist at a tech vendor with 10,001+ employees
Enables seamless data replication and supports comprehensive data analytics workflows
The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites. Also, important is the capability to provide RESTful APIs for custom connectors. In terms of security, I advise customers to rotate access keys to enhance protection. Additionally, scalability is effortless as you can add nodes or expand the license.
Sachin Prakash - PeerSpot reviewer
Assistant Consultant at a tech vendor with 10,001+ employees
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

"Technical support is very good."
"The ease of use. That's what our customers love. They say it's very easy, they don't need special training, they don't need to call us or any other company or integrator to help them do their job. That's the main reason they purchase Pure."
"The speed is the most valuable feature, along with the ease of getting it connected. We were able to get it online in less than a day."
"Their support is top-notch, and their NPS scores reflect this."
"The support team is available all the time and they seem to know what they are doing."
"In Pure Storage FlashArray, the dedupe and compression are excellent, and performance is good too."
"Before we used Pure Storage it took 93 days of employees who run the database to back up and restore databases, and the scale of deployment basically went from several days to a few minutes."
"The job of support for the storage engineers dramatically changed. We know more quickly the automation of the provisioning. We can now focus on things that bring more value to the company than just managing storage."
"Overall, I rate IBM Cloud Object Storage a ten out of ten."
"The integration itself is pretty easy. The access appliances create the connection between both environments."
"IBM has the most number of additional services, this is the main advantage."
"One of Cloud Object Storage's best features is infinite capacity."
"The standout feature of IBM Cloud Object Storage is its top-notch security, making it ideal for sensitive applications like mobile financial transactions."
"IBM has the most number of additional services, this is the main advantage."
"IBM Cloud Object Storage integrates well."
"The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites."
"I rate this product ten out of ten."
"It makes our file system sharing a lot easier, even across different continents. We have had file systems shared across different continents with no performance degradation."
"Spectrum Scale is one of the most important products in our environment now."
"There is nothing else that even compares to Spectrum Scale."
"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."
"I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system."
"The profile share is a valuable feature."

Cons

"I would like to see additional features like performance monitoring, configuring alerts, and the customization of alert thresholds."
"It would be nice if Pure had something in its portfolio that provided higher deduplication and compression for backups."
"It can go down from time to time, but it's been pretty solid so far."
"Self-backup is the only feature lacking in this solution."
"When creating a support case, visibility should be extended to others involved in assisting."
"The latest release contains bugs that shouldn't be in a production environment. Two incidents impacted our client, including hardware-related bugs. They need to be more cautious in testing before they release."
"The product should improve its response time. I have also encountered issues with its configuration."
"Larger capacity and more storage ports would be the two things I'd like to see."
"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."
"One improvement could be incorporating a feature similar to Dropbox's version history. This would allow users to track modifications made to files over time, which is particularly important for maintaining a record of changes. While the free version might not include this feature, it could be included in the paid version to provide added value to clients. Additionally, having a version history feature that allows users to access modifications made to files over the past three months could be beneficial."
"Room for improvement depends on customer needs. Some customers prefer pure Object Storage using the S3 protocol, while others use a gateway in front of the storage grid to enable CIFS or NFS."
"IBM Cloud storage is not cheap, but it could be."
"Sometimes technical support lacks a comprehensive understanding of the entire solution, only focusing on the product they support."
"One area where IBM Cloud Object Storage could potentially improve is in modernizing its underlying codebase."
"The performance could be better. It isn't bad, but everything is network-based, so you have a performance penalty on the network. You can never achieve the same performance as hardware. That's the disadvantage of cloud storage solutions in general. Cloud performance is one of the main issues clients have."
"The performance could be better. You can never achieve the same performance as hardware, and cloud performance is one of the main issues clients have."
"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."
"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."
"The initial setup is complex, especially if trying to avoid erasure coding, as it requires more discs. Avoiding erasure coding can significantly increase costs."
"Integration with other vendors is not available. This feature would be very helpful."
"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."
"We do not feel as a company that the product can grow with us anymore, so we are not going to use it anymore."
"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."
"Initially, stability was a concern as we encountered numerous issues and errors."
 

Pricing and Cost Advice

"Dell and Pure Storage offer competitive pricing, but Pure Storage might have a slight advantage."
"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."
"The pricing of Pure Storage FlashArray is reasonable."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"The price-to-performance is good. I looked at Pure about three to four years back, but the price-to-performance wasn't right for us. Now, it's right."
"The price is very reasonable when compared to other solutions."
"When you are paying more than you were paying for the storage space, you'd like the cost to be less. If they could get into the spinning disk kind of cost, that would be it."
"The pricing of Pure Storage is all-inclusive. It is very fair, and very easy. In comparison, Dell EMC has licensing that needs to be added if you wan to work in a complex environment or in specific functionalities."
"IBM Cloud is cheaper than AWS. If you want to scale your cloud infrastructure, it can be bought at almost the same price."
"Pricing is not cheap."
"You have the option of a monthly or yearly license. Most customers choose the monthly option. I understand what you would like to say. IBM also lets you choose among four types of Cloud Object Storage. The difference is usage, performance, etc. Of course, high-performance storage is more expensive, while low-performance storage is for cold data, and it's really cheap."
"Like most cloud providers, IBM likely charges based on storage capacity, typically per gigabyte or terabyte. Their pricing is competitive when compared to AWS or Microsoft."
"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."
"The solution is costly but reliable."
"The licensing is based on the number of terabytes."
