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.

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.

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

"The solution offers amazing performance."
"The solution helps to simplify storage."
"The features that are there now are really what we need."
"We were actually able to do multiple upgrades, including head upgrades and moving between the platforms, M20 and M50, over the years. We have never once lost a ping and have never had an outage due to an OS upgrade or a complete head upgrade."
"The best features of Pure Storage are their support and analytics."
"The most valuable feature is it never goes down. We can expand and create volumes."
"The all-flash disc is the most valuable feature of this solution."
"The most important feature of any storage array is its reliability, measured by its uptime."
"The integration itself is pretty easy. The access appliances create the connection between both environments."
"One of Cloud Object Storage's best features is infinite capacity."
"One of Cloud Object Storage's best features is infinite capacity. This is one of the main advantages if you don't want to use your own storage. You also have the ability to write only, write once, and read many. It's like tape storage but software-based. This feature is essential for financial institutions that require that kind of protection if you write backup or data there."
"The most valuable feature I like is when you connect it via CLI plug-in...It is a stable solution."
"The standout feature of IBM Cloud Object Storage is its top-notch security, making it ideal for sensitive applications like mobile financial transactions."
"Overall, I rate IBM Cloud Object Storage a ten out of ten."
"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."
"Since the storage space is local to the hosts, it reduces the overall response time and improves the performance."
"The product's initial setup phase is simple."
"The performance has exceeded our expectations and exceeded our traditional converged infrastructure."
"This solution is super stable."
"The most important feature to me, in my role, is cost. In the renewal cycle for storage, it was about a 40 percent saving compared to going to an all-flash array, which is what we first looked at doing. Secondly, performance: we need clinical data access in five seconds and need to do everything we can to retain that metric. Thirdly, I was really pleasantly surprised during the data migration across to vSAN, that it happened almost instantly whereas, in the past, migrating from array to array was an arduous and fraught process."
"VMware has been around for a long time and is doing a decent job at catching up with the latest technologies, i.e. bringing in Kubernetes and containerization, and overall, this is a great tool for virtualization."
"The solution is easy to deploy and manage."
"The valuable feature of the solution is the total hyperconverged facility."
 

Cons

"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."
"I feel like there is too much automation; the user doesn't have any manual input."
"They need to find another way of doing data protection, RAID is not working very well."
"Pricing could be better in comparison to other solutions."
"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten."
"They should work on their upgrades, they're not smooth."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"Price is about the only thing that's wrong with it."
"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."
"One area where IBM Cloud Object Storage could potentially improve is in modernizing its underlying codebase."
"Sometimes technical support lacks a comprehensive understanding of the entire solution, only focusing on the product they support."
"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 improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."
"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."
"IBM Cloud storage is not cheap, but it could be."
"IBM has limited cloud storage."
"I would like to see better performance graphs, maybe something that you can export outside to a different console, and maybe a little bit longer time period."
"The price is expensive. This solution is not an option for SBM customers because of the price."
"I would like to see replication as part of it. I would also like to see direct file access, being able to run SIF shares and NFS and the like. I think that would be critical to continuing the use of it going forward."
"The only thing I care about is that the solution is stable, reliable. They need to improve on those factors."
"We are facing some problems with updates with the VMware vSAN. When we upgraded from version 6.5 to 7, we have been faced with many problems. They have been deploying many hotfixes for this version, and they need to continue to improve this version."
"VMware vSAN needs to improve its features because other solutions have more advanced features."
"There is room for improvement in vSAN's ability to debug. When it's not working well, debugging becomes quite challenging. Identifying issues when it's lagging or not functioning properly can be difficult."
"One of the things that we've had challenges with are when we place hosts into maintenance mode. Sometimes doing so triggers large re-sync processes which can be time-consuming and which have, at times, pushed the capacity to the threshold. I definitely think making some changes in that area would provide some big improvements."
 

Pricing and Cost Advice

"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."
"Pricing is very competitive, and it's better than other competitors."
"Our licensing is on a yearly basis. So, every year, we renew. We could do a three-year contract, but right now, we only do a one-year."
"The best features come included without any additional cost."
"It is a cheaper solution."
"Because of the SSD, it is cheaper because I am not purchasing so many disks."
"We purchased a license to use this solution and we pay for the storage ourselves."
"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."
"Pricing is not 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."
"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."
"IBM Cloud is cheaper than AWS. If you want to scale your cloud infrastructure, it can be bought at almost the same price."
"The cost is expensive. I purchased two servers. The hardware cost was $19,000. The software cost for these two servers, including the vSAN, was $30,000, which is $11,000 more than the hardware. Then I had to pay another $5,000 for installation and implementation for professional services. In total, it was $54,000 for two vSAN Servers."
"​I would like to see this technology be made available to smaller businesses, who might benefit from high availability but struggle with the entry fee.​"
"It is too expensive."
"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."
"If you compare the price of VMware vSAN with other players like Nutanix and Cisco, its price is good, but could still have some improvement."
"I have been told that if I used VxRail it would be cheaper than the system we are using now with buying the products separately. The solution is expensive overall."
"It is expensive, but you get what you pay for."
"The licensing cost is high and should be taken into account."
