All-flash storage has unified my clients’ workloads and has reduced TCO through efficient data services

The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors. IBM, Lenovo, and Dell are more aggressive on prices. It is a very complicated market, especially now, and I understand the prices are higher at Everpure because of the software and all the enhancements it has. However, in this competitive market, we have a big problem selling to customers that are on a tight budget. A product with better pricing would be a win in the end. The RC or C20, for example, was a very good product that I could sell more easily than other options. Everpure FlashArray//C is sufficient for most workloads and virtualization workloads if you do not have very large databases. A product like that helps, and perhaps a new product in the future that is a little cheaper than the current options would be a possibility to gain more market share. I see the return on investment clearly from using Everpure FlashArray, but the challenge is selling it to customers for the first time. There are many customers who fall in the sweet spot where they are too small for an X or even a C model. They need something a little cheaper, they have the money for a cheaper version, and they need the performance of a Pure system. These customers could be more easily approached if Everpure offers a version of a local device in the future that is even cheaper than the C-class. I am trying now to help customers understand the concept behind AG1. I know that AG1 is not profitable if capacity is less than 50 terabytes. However, some customers would be very willing to pay for 25 terabytes in a cloud operated by Pure and to have it accessible with very good speed. We will see what the future brings.

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.

Optimized storage has supported high availability but performance and node limits still need work

The performance of Microsoft Storage Spaces Direct is challenging when trying to support both NVMe and SATA SSDs, and there are problems regarding performance that need to be addressed. I have found that performance is not as good as expected with Microsoft Storage Spaces Direct. It is risky because of quorum; it is better in three nodes, but my budget only allows for two nodes, so I need to use a witness, which is not an optimal configuration. I am not using the automatic rebalancing feature that much in Microsoft Storage Spaces Direct. I have not utilized nested resiliency in my operations. I am using the most standard features available in Microsoft Storage Spaces Direct.

More Microsoft Storage Spaces Direct pros

Cons

"I would love to see a true one click upgrade solution. Right now, you have to click and schedule an appointment with Pure Storage to be able to upgrade. I would love for it to automatically download, install, and fall-over every controller as it updates."

"The price of this solution is high and should be lowered."

"There are a lot of things to improve."

"Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE."

"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."

"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."

"The solution could improve by having a multi-tenant feature."

"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."

More Everpure FlashArray cons

"Technical support is sometimes good and sometimes it is low."

"I hate I/O groups. If you start swapping I/O groups, they can be potentially risky. If they could get rid of the whole I/O group principle, the risk is not there anymore. I understand the fundamental thing about I/O groups, but they are risky."

"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."

"IBM could improve IBM Spectrum Virtualize by bundling Storage Scale and Storage Virtualize into a single appliance. This would provide a more appealing and cost-effective solution."

"Anything which improves performance and the ability of our systems would be a nice."

"We've had some issues with the production rate behind SVC."

"There are a few little GUI issues and stuff like that, but nothing major."

"Because we're so big, they have a little bit of trouble tracking all the products and making sure we get connected with the reports, but, in general, they are very good."

More IBM Spectrum Virtualize cons

"The integration is not difficult because there is no GUI, but we need to use a PowerShell command. This makes it difficult to monitor and to see the components' statuses."

"It is scalable, but only beyond two nodes. If I go for two nodes it's not scalable. I need to build a complete cluster from the beginning if I'm going for two nodes."

"It is difficult to get a hardware compatibility certification for the solution."

"Documentation management could be improved"

"Microsoft's frontline support is not adequate if you rely on this for your business."

"There is a lot of room for improvement. I would like to have more tools to monitor the function and problems."

"The performance of Microsoft Storage Spaces Direct is challenging when trying to support both NVMe and SATA SSDs, and there are problems regarding performance that need to be addressed."

"The management tool within this solution could be improved. We would also like to be able to access services like Azure when using this solution."

More Microsoft Storage Spaces Direct cons

Pricing and Cost Advice

"Pure Storage has not helped to reduce our HANA licensing costs."

"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."

"While it comes with a higher price tag, this investment often translates to significant improvements in performance."

"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."

"There are no fees for licensing. The hardware is paid for only once."

"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 price of Pure Storage FlashArray is expensive."

"The solution could be cheaper."

More Everpure FlashArray pricing and cost advice

"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."

"This solution came as an additional cost for the TSM package we chose."

"We would like the CPU cycle to save more on the licensing costs for us."

"We have struggled with Pure Storage, but people are understanding that much of Pure has been consumer grade SSDs. Therefore, when the customer is really understands what they are getting, they realize that IBM presents the same sort of value as existing vendors."

"It has a lot of advanced functions for a reasonable price."

"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."

"The entry point of pricing for this product is the most amazing price ever in the industry."

More IBM Spectrum Virtualize pricing and cost advice

"With the data center licensing and everything that is connected to that, this solution is relatively costly."

"Cost-wise the product is one of the more affordable within the category of products."

"The solution is expensive."
