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.

A robust solution with good performance and support

This is a solution that scales well, although I think that we have stabilized in terms of use. With respect to scalability, we have an open question as to whether we will be able to grow into a cloud-based deployment. We don't know in what ways this solution will assist us with the migration, or whether we can still use it for DR. We don't know about the type of backup, be it full, incremental, or otherwise. We are also looking for a cost-savings if we migrate. These are things that we will find out over time. We have about two petabytes of data.

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

"Now with Pure Storage, our developers work a lot faster and more efficiently which has definitely improved our productivity."

"Cost, racial per terabyte, and speed is why we chose PureStorage. It was no brainer."

"It gives us capacity planning."

"Non-disruptive upgrades: You can upgrade at anytime without worry."

"While all these products have their own uses, Pure Storage FlashArray is in a market of its own."

"It comes with a large number of features out-of-the-box, which makes it easy for us to see problems and manage capacity."

"I find Pure Storage FlashArray to be much better than traditional storage because it has a GUI interface. It makes the process of allocating the storage much easier, and most activities are automated. It is like clicking a button for every task."

"The features that are there now are really what we need."

More Everpure FlashArray pros

"The most valuable feature is the robustness, which is typical of IBM because their software generally just works."

"The ease of use is the solution's most valuable aspect; it's very user-friendly, and the security on the product is very good."

"Implementing this solution has been a very good decision for our in-house data center."

"It's improved the organization overall primarily because the storage is local on the boxes."

"The most valuable features are ease of deployment, and ease of management. If you compare it to other software-defined storage products, it's much easier. It's a checkbox. It's lot easier to manage."

"Flexibility, growth, and expansion are probably the more important features for us. As our environment grows, the more users come on, the more VDI workstations that we need, we can easily expand either horizontally or vertically with the environment"

"Instead of going for SAN storage, customers can use the scale-up and scale-out features of VMware vSAN."

"One of the valuable features of vSAN is it has a universal type of technology that allows you to deploy it on any server or hardware. Competitors, such as Nutanix, provides the AOS and can be deployed only on certified hardware. For vSAN, it does not require any kind of certified hardware."

"Since the storage space is local to the hosts, it reduces the overall response time and improves the performance."

"We had very good access to technical support."

"Some of the valuable features of this product are: Software-defined class which is one of the building blocks for SDDC, flexible as it scales as and when needed, simple as it is easy to manage, and high performance as the local server can access data at full speed with low latency in SSD, while the absence of network-attached storage appliances lowers infrastructure cost."

More VMware vSAN pros

Cons

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

"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."

"It was a little costly."

"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."

"The solution is not cheap. It's much more expensive than DataCore."

"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help."

"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."

"I would like to see support for NVMe, end-to-end."

More Everpure FlashArray cons

"The interface is not user-friendly so the ease of use could be improved."

"The reporting mechanisms need improvement."

"Hackers are able to manage to leak information or data from the product using some corrupt files, making it an area of major concern where improvements are required."

"Reporting currently depends on third party applications and that could be improved."

"Some of the earlier versions were a little rough; we saw some weird, crooked behavior."

"VMware vSAN needs to improve its features because other solutions have more advanced features."

"The list of hardware supported should be increased in the future."

"The big thing is pricing, and the rest of it is mostly good. From a scalability point of view, scaling the storage from network or compute should be easier. It is again all around the cost, and it would be good if it was easier to scale your storage separately from your compute."

"Based on my testing, I would like to expand deduplication to include hybrid deployments and not just for all-flash deployments."

"I have used the VMware Replication but I can't get it to work properly. The process should be simplified."

Pricing and Cost Advice

"The price of the solution can be a bit expensive. There is an additional fee for support."

"Pricing is very competitive, and it's better than other competitors."

"We have seen a reduction in TCO."

"There are no licensing fees aside from the support."

"Dell and Pure Storage offer competitive pricing, but Pure Storage might have a slight advantage."

"It could always be lower, but it's okay."

"The price is very reasonable when compared to other solutions."

"We purchased a license to use this solution and we pay for the storage ourselves."

More Everpure FlashArray pricing and cost advice

"For a database, on a yearly basis, we pay approximately $3,500 for licensing fees. The solution is sold as a subscription on a yearly basis so there are no other ancillary costs."

"If you are cost-sensitive then this solution is not for you."

"We have increased our user productivity."

"ROI from an administrative perspective is clearly much better because I only have to deal with one user interface."

"If they could reduce the cost, it would be better. Licensing costs are something that they could take care of. If you are a smaller and strong IT team, then VMware vSAN is a very good product. If you want to expand in the service provider space, then you will have to go for an open-source solution like OpenStack. We are now looking at OpenStack because we sell licensing costs. We are a service provider, so the IT component data is a substantial component in our overall costing. We feel that OpenStack might help us to cut down the licensing cost. Therefore, we are looking at SAS storage instead of vSAN. SAS is open source, but it is not wise to have open source without having the backend support. We are using RedHat SAS, and it is an open-source solution. You can also have a free version, but we are using it with support from RedHat so that we have somebody to back us up in case we have a problem. If you do normal business, then IT expense is 1% or 2% of the total turnover. The higher licensing costs sometimes don't make difference to the big companies who are not service providers and are using it only for their internal use. For them, the IT cost is 1% or 2%, but for an IT service provider, the IT costs will go up to 15% to 16% of the total cost of the operations. This is where the licensing costs become irrelevant. For example, the licensing cost of using VMware, VC, and vSAN is 8% of my monthly revenue. Every month, I pay about $35,000, and, with the revised plan, it will be something like $50,000 or revenue of 600k per month, which means almost 8% of the revenue is going into VMware licensing. In a very competitive world, 8% as a cost element is huge. So, if I can bring it down to 2%, I save 6% in revenue expenditure. In terms of profit, 6% of 30% is something like another 25% increase in my profit. My profit can be almost 25%. It would be 20% to 25% in case I am able to handle the licensing costs and bring them to a very low level. Because these IT costs are substantial for us, that is why we are going with OpenStack. OpenStack has a limitation that it requires more hardware. There will be some increase in the hardware cost, but overall we will save 5% to 6% of our licensing cost by using OpenStack."

"Basically, vSAN is a license in addition to that of the classic VMware Vsphere, which is also mandatory."

"Due to recent changes in VMware's licensing approach by Broadcom, the cost has increased significantly, making it less attractive from a cost perspective."

"I'd love for this product to be cheaper."

"The vSAN is somewhat expensive to license."

"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."
