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.

Unified storage solution supports cross-vendor replication and diverse industries
One of the most valuable features of IBM Spectrum Virtualize is its virtualization capability. It allows for the creation of stretched clusters, which are crucial for running Linux-based workloads that need mirroring for boot disks. The solution also provides asynchronous and synchronous replication, supporting operations across different data centers. Its deployment options across public, private, and hybrid clouds add to its versatility.

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 most valuable features I have experienced are the centralized management and redundancy under speed of the right disk."
"It overperforms both in terms of storage capacity and throughput, and bandwidth capability."
"After moving to Pure Storage, I have noticed that our databases are considerably faster and our performance has improved by at least four times."
"It simplifies building out the storage."
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"The deduplication and compression meet all of our system requirements."
"This solution has improved my organization because it has good performance."
"All updates, upgrades, and hardware work are all performed on-line with no impact."
"Migration from configurations where servers have storage provisioned from older SAN disk systems to newer storage systems is almost seamless using image mode migration techniques, with only a short outage of the servers."
"There are many benefits to this solution. Storage virtualization and the ability to migrate massive amounts of data to other systems without impacting your client are the most valuable. It is non-disruptive for my users. We migrated 350 terabytes of data in one night to a new machine without a small system going down and a single user complaining about the performance. You have to fine-tune a lot of storage machines constantly for performance and for making sure that they are optimal, but IBM Spectrum Virtualize does this by itself. It does the adjustment on its own, and it does it right. That's what makes it different. I had a huge VSP from Hitachi, which is also a type of virtualization-based engine but with a decent size. It was a continuous performance-tuning exercise. I never had that issue with IBM Spectrum Virtualize."
"The abstraction flair and the abstraction layer. We had a mixture of different storage arrays, and the wonderful thing about SVC is is that it normalizes all it into a single driver. A single view that all hosts see simultaneously."
"IBM offers excellent customer service."
"It has the ability to seamlessly move hardware in and out as we refresh technology."
"Although the GUI from the XIV was used (in my view), IBM has polished and refined the GUI providing a pleasant and easy to navigate GUI experience."
"The IBM Spectrum Virtualize has gone from strength to strength but at the same time setting the bar for what's possible in the storage virtualization market."
"Across the industry, nobody matches it."
"The product’s most valuable features are performance and expandability."
"The total cost of ownership, as it's really cheap for us and we have budgetary constraints, plus, as we're a hospital, doctors need to access their patient data quickly, which VSAN allows them to do."
"The most important thing is the simplicity of the product. It is a well-established product with good stability."
"The performance for us is very good."
"It completely removes the need for a storage network and for a storage administrator and all of that infrastructure and the costs that are involved with them."
"It easily integrates with all types of storage."
"The product’s ecosystem is better than Nutanix’s."
"The setup is straightforward."
 

Cons

"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."
"The difference in pricing could become a problem for Pure because the commoditization of the solutions could lead to a different price being a problem."
"We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client. The current plugin for Pure Storage doesn't show up in that client at all. You have to go and use the legacy FlexFlash client to see the Pure Storage plugin in vCenter."
"Organizations with security concerns that prevent cloud utilization would benefit from a wider range of instruments available for offline operation. Currently, the limited selection of on-premise instruments hinders Pure Storage FlashArray's ability to compete effectively with other vendors."
"From a scalability perspective, it is a very small storage solution, so it's not very expandable."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"I would recommend improvements in the graphical user interface, specifically a detailed hardware view that would allow us to see the individual drives and individual controllers more easily, as currently, they are presenting only a higher-level view."
"The GUI could improve, it could be more intuitive. There is hidden functionality."
"The integration would be an option that we would like, but I understand that's not how it's going to be implemented."
"It's been pretty stable, but we've had some issues. I wouldn't say it's poor, but the resiliency has been less than what we expect from an enterprise class product."
"I have encountered stability issues in situations when the customer-provided AC power has defects."
"There are a few little GUI issues and stuff like that, but nothing major."
"Cheaper pricing and GUI should be developed in HTML5 as opposed to Java."
"Sometimes IBM documents something, but in the real world, it doesn't work."
"There are big arrays now, and if a customer wants add more disks to it, you have to have another array. Adding disks to existing arrays is one of the most demanded things from our customers."
"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."
"In a future release, they could add micro-segmentation or security level features integrated into vSAN."
"Reporting currently depends on third party applications and that could be improved."
"The solution functions as the marketing says, as long as you follow certain rules."
"There is room for improvement on the latest version of compatibility with the VMware product, especially for vSAN and with other vendors, like Intel and AMD, on their motherboards and driver configurations."
"This solution is expensive."
"We would like to see additional backup and recovery options added. In particular, integration with popular applications like databases."
"The pricing could be better when it comes to renewing the licenses."
"There are some minor things wrong, but its potential value could far overshadow its current weaknesses."
 

Pricing and Cost Advice

"The price of the Pure Storage Flash Array is too high and there needs to be more contact clarity. We went with the Evergreen plan and I don't have clarity on what am I supposed to pay each year or every three years. There was not much contract clarity."
"The licensing is $100,000."
"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."
"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"It is a cheaper solution."
"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"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."
"Generally the bundled licensing is more cost effective and gives flexibility to the solution. Linking into the Spectrum Suite can also be advantageous, but depends on the scale of the enterprise."
"I think it is a good value for the price."
"We would like the CPU cycle to save more on the licensing costs for us."
"It has a lot of advanced functions for a reasonable price."
"This solution came as an additional cost for the TSM package we chose."
"The entry point of pricing for this product is the most amazing price ever in the industry."
"I am very happy with the pricing. There is no comparison when it comes to pricing. I have looked at all solutions from EMC, Veritas, Hitachi, Dell, etc. None of them compares to IBM when it comes to pricing. I get great pricing from them."
"Do a proof of concept, if you are not comfortable jumping in, but do it."
"From a cost perspective, it is expensive. From a usability perspective, it reduces the overhead costs attached to its users' servers."
"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."
"The solution is relatively expensive compared to similar products."
"Enterprise customers can customize their licenses according to their own needs and budget."
"The product's price is not high. The tool is available at a normal price."
"ROI from an administrative perspective is clearly much better because I only have to deal with one user interface."
"Users may also start off with the demo version of the tool. After you learn to use the solution, you can buy it if it is beneficial."
"It could be cheaper."
