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 performance levels and the storage have improved my organization because we're a 95% virtualized environment and we're able to allocate resources as needed and manage our whole infrastructure that way."
"When you put all of the features in a box, leverage them and migrate your application to one of these arrays, it will give you a lot of benefits."
"We experience fast demos and zero downtime; we do not experience any downtime with Pure Storage, thanks to resilience with Safe Mode, integration with backup software, and everything related to cyber resilience."
"Their evergreen solution is probably the most needed in any industry, especially today in unprecedented times and supply chain issues, their evergreen solution is amazing."
"Everpure FlashArray has positively impacted my organization, particularly in performance and reliability, as we've had good improvements, making our applications run faster and giving us more confidence that they will not crash."
"The management features are well organized and they have a very good dashboard."
"You get what you pay for; it is expensive, but it really works, so I would really recommend using Pure Storage."
"The most valuable features would be its performance, retrieval, recovery, and backup, and it meets the customer's expectations."
"One of Cloud Object Storage's best features is infinite capacity."
"The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites."
"The most valuable feature I like is when you connect it via CLI plug-in...It is a stable solution."
"IBM has the most number of additional services, this is the main advantage."
"IBM Cloud Object Storage integrates well."
"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."
"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."
"The feature we have found most valuable is the compatibility of VMware products with VCF and VMware Cloud Foundation."
"VMware vSAN is the most trending hypervisor that most of the customers are working with and I would recommend this solution to others."
"VMware vSAN's most valuable features are the capability to consolidate standalone physical infrastructure into virtualization and the ease of management."
"Have a look at the simplicity of vSAN and how it easily integrates into the existing management tools."
"The most valuable features are its price point and that you can use existing storage; no specific storage requirements are needed."
"The solution is quite stable, and although we have encountered some minor issues, overall we are quite satisfied."
"While we haven't made major changes to our disaster recovery and business continuity processes yet, moving towards stretch vSAN across sites will simplify and expedite our DR processes in the future."
"By eliminating dependency on that back-end storage, we now depend on everything that's in the VMkernel with vSAN. We eliminate the middleman."
 

Cons

"I would like to have support available in Spanish."
"Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations."
"I would like FlashArray to add reports that help us forecast our predicted resource needs based on current usage."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"I wish they could add more of a monitor on the machine itself so you don't have to rely on a KVM or something to look at the display, such as an onboard diagnostic display."
"We would always like to see higher performance, and lower pricing is always better."
"Once, before Pure went public, we were a member of their customer advisory board and beta tested replication. One requested enhancement yet to manifest is the scheduling of snapshot replications."
"We ran into some issues with the program at first and we had to work around those issues to fix our problems."
"One area where IBM Cloud Object Storage could potentially improve is in modernizing its underlying codebase."
"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 has limited cloud storage."
"If I had to choose one area, it would be making the consoles more intuitive would be helpful. Sometimes, they can be a little complicated if you're not familiar with them."
"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."
"Sometimes technical support lacks a comprehensive understanding of the entire solution, only focusing on the product they support."
"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."
"As no product is 100% perfect, the price for VMware vSAN could still be improved, though it is good when compared to some of its competitors."
"I am not satisfied with VMware support, particularly with the reaction times, SLAs, and those kinds of issues."
"I was not sure about its stability because we have a big SAN shop and I got the impression that it’s good for small offices and not the larger ones."
"I would like to see the availability of more template based VMware systems. Combined with the ability to check and measure multiple and converging data segments. Another issue I've seen is that the tool seems to be slow when first starting up."
"The product's high price is an area of concern where improvements are required."
"The monitoring feature in VMware vSAN could be better."
"The vSAN Hardware Compatibility List Checker needs to improve, since currently it is a sore point for vSAN."
"VMware vSAN could improve by having faster reload time and a single point of failure. Resynchronization of many hardware could be better. If you have an outage of a disc or a full system, the replication time is too slow. This has room for improvement."
 

Pricing and Cost Advice

"FlashArray is expensive, but the quality justifies the price."
"We purchased a license to use this solution and we pay for the storage ourselves."
"There is an annual or perpetual license required for this solution."
"It's priced higher than the market."
"Pure Storage FlashArray is expensive."
"We have seen a reduction in TCO."
"The cost has room for improvement."
"The pricing is an issue. However, being all-flash, it will always be sort of expensive."
"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."
"IBM Cloud is cheaper than AWS. If you want to scale your cloud infrastructure, it can be bought at almost the same price."
"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."
"Pricing is not cheap."
"The only problem I have with VMware is the price. It is a good product, but it is expensive."
"I would like to use more advanced models of the solution but the price needs to be reduced. There are some extra costs for this solution including a license."
"It is not that expensive, and it is not even cheap. If it is designed in a proper way, it has good pricing, but if you do oversizing, the price will be high. There are different licensing models."
"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."
"This solution requires the purchase of a license."
"It is expensive. It should be cheaper. It has a perpetual license as well as a subscription-based license, but they are moving towards subscription-based licenses."
"The price of vSAN could be lower."
"It is an expensive solution. There should be more flexible with licensing to allow small businesses the essentials of the solution's features."
