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

"We have seen savings in our storage, and the speed of deployment has gone from several days to a few minutes, reducing backup and restore times from 93 days to minutes and simplifying storage for us."
"The amount of data that I have moved to it from legacy storage has enabled us to retire units that are three or four times the physical size."
"Everpure FlashArray is very good with AI development and is very suitable for low downtime and critical mission storage, so customers who need critical mission storage and those chasing performance should consider this solution."
"The features that are there now are really what we need."
"From an intangible standpoint the lack of care and feeding is notable and freed up the Storage Team to do other things."
"I would recommend Pure Storage FlashArray to other users because, first, the speed that I get with Pure Storage FlashArray is not remotely possible with any other product at this price range, and second, the support is absolutely fantastic."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."
"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."
"The ease of management, the simplicity of the CLI, the speed of that interface, and the well-architected design of the product in general are valuable features."
"Good luck finding anything that does half of what it does."
"It is a single pane of glass management interface, so once the storage is allocated to SVC, they only have one place to go to manage it for everything."
"I love the SVC."
"It helps us to reduce time, reduce complexity, and be more responsive to requests instead of taking an hour to do one volume; now I can do one volume in less than two minutes."
"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."
"It has the ability to seamlessly move hardware in and out as we refresh technology."
"We are very satisfied with this solution."
"Stability-wise, I rate the solution a ten out of ten."
"The feature we have found most valuable is the compatibility of VMware products with VCF and VMware Cloud Foundation."
"Without doubt Virtual SAN 6.0 is a storage solution that realizes the VMWare defined storage software or SDS (Software Defined Storage) offering great benefits to both customers and the vSphere administrators who every day we face new challenges and complexities."
"My advice is if someone is interested in VMware vSAN it is a good solution; it is stable, supportive, and compatible with many solutions, and customers have to consider when choosing VMware that they receive a lot of features, such as replication backup, and if they went with another solution it would be more expensive."
"I advise those people that have a large amount of data and they need very fast retrievals, they must use the scalable feature of VMware vSAN."
"Performance-wise, it has gone above and beyond what we originally spec'ed it for."
"vSAN can help customers save on storage system costs, and also save on the human cost."
 

Cons

"We would like to see more cloud support, which we know is coming, although it's not out yet. It's going to be released in the next versions. That would be the biggest win, if additional cloud support is built into the array."
"The interface lacks the same level of control as some other arrays I've used."
"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."
"The only minor issues that come to mind are that, every once in a while, a hard drive will go bad. Also, the solution should be cheaper."
"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve."
"The price could be better."
"We had one instance with an eight-hour outage in our primary data center because the upgrade to the controller failed, and the controller redundancy didn't work."
"The initial setup of the product is complex."
"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."
"I have encountered stability issues in situations when the customer-provided AC power has defects."
"Technical support at IBM is actually not as great as it used to be. It seems like IBM has decreased the number of people who can support this environment."
"There are things that occur when you get to this size and capacity. We're very large, i.e., petabytes. When you get to that sheer volume of the numbers of things, it is too big for people to keep track of."
"Technical support is sometimes good and sometimes okay."
"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."
"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."
"I would like to see them provide a unified platform that offers block, file, and object-based protocol access."
"It's not quite there yet. We've had a few outages that were addressed."
"Their level one and level two support is not at all good, and it should be improved."
"The problem for many is that you become dependent on Broadcom; you have no competitor then, and you are stuck with it."
"Hardware compatibility needs to be increased to be able to use more RAID controllers available on the market."
"Enterprise customers get discounts on the solution's licensing pricing, but it is too expensive for SMB customers."
"Better options would be clustered nodes, or even cloud configuration. There is room for improvement in cloud configuration, we typically do web browsing for management."
"Areas of improvement could be the UIs. The UIs are kind of cumbersome."
"The technical support, it's not satisfactory. Whenever we raise a ticket it takes a lot of time to have an engineer get involved sometimes, or we receive a less experienced engineer. We then have to repeat the situation to the next engineer which all takes time."
 

Pricing and Cost Advice

"It is light years beyond anything else with the same price point."
"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."
"We have seen a reduction in total cost of ownership."
"Because of the SSD, it is cheaper because I am not purchasing so many disks."
"There is always room for negotiation."
"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."
"We evaluated Oracle and Hitachi, but Pure Storage had the better pricing."
"The price is reasonable."
"It has a lot of advanced functions for a reasonable price."
"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."
"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."
"The entry point of pricing for this product is the most amazing price ever in the industry."
"Do a proof of concept, if you are not comfortable jumping in, but do it."
"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."
"There is a license required for this solution, it is a one-time payment. However, if they want support for the solution, it can be paid annually or for three years."
"We pay for a license to use the solution through our company CapEx and then we continue to pay annually."
"I would rate the licensing model a three out of ten, where one is expensive, and ten is cheap."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a seven out of ten."
"The solution requires a license. The payment is on a yearly basis and It is not overly expensive."
"VMware vSAN is an expensive platform. We purchase its yearly license."
"The licensing cost is high and should be taken into account."
"It is slightly expensive. They can be more competitive in terms of pricing."
