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.

Meets our customers' needs but they should move towards high-level scaling

I the product already has scalability features, but in terms of size maybe they could do more to work with parent storage and move to high-level scaling. That area, I feel, is a place where there could be some more options in this solution. It would be a way to improve the scalability in another direction, maybe options to scale out rather than just up. So far we have done very few installations. So maybe in the coming days, weeks and months, we would be able to come up with some additional features that are needed, but right now the product has the competitive features that our clients need.

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 tested our VDI environment on this array and it performed flawlessly and boosted the user experience."

"It makes things ten times easier."

"We were previously on legacy storage systems, and after moving to Pure Storage, our stability and performance both drastically improved."

"The best features Everpure FlashArray offers are the speed and dependability, which are the main features that we get from Pure; it is faster than its competition, and we do not have any documented downtime from it ever."

"The deduplication in the array combined with its snap technologies allows the product to be remotely/manually controlled or scheduled."

"Pure Storage technology allowed us to automate tasks, reducing something which started as a 12-hour turnaround down to about 15 minutes."

"The reliability is very good."

"We transferred our old architecture from hyper storage to all-flash storage, which made our business faster and more connected to our customers."

More Everpure FlashArray pros

"Comparing other products that are competing with Dell EMC (Enhanced Memory Controller), Dell seems to us to always come out on the high-side."

"We are using it as the primary virtualization storage (both for internal corporate users and external customers) for VMware and Hyper-V virtualization platforms."

"Automatic rebalancing is the feature saving administration time, and also auto rebuilding."

"The ScaleIO UI: EMC has been working with storage for a long time; therefore, they know how to clearly present any important data, including data flow and each drive's IOPS/bandwidth, and allow the user to easily monitor bottlenecks and problems, especially the rebuild and rebalance status of child objects."

"If you are going for features, scalability, and performance, VMware is the best solution."

"The implementation is simple, it was very straightforward. It took us approximately three weeks because it was installed in four locations."

"vSAN is software-defined networking; the advantage of vSAN is that if one of the servers goes down, nothing happens."

"VMware vSAN has greatly reduced refresh spending."

"Personally, VSAN is the best solution for most customers and workloads."

"We had very good access to technical support."

"vSAN that has been most effective in streamlining storage operations. For data recovery alerts, it uses tools like snapshots and vMotion."

"The product's initial setup phase was very straightforward."

More VMware vSAN pros

Cons

"We haven't seen ROI yet."

"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."

"In the next release of the solution I would like to see Vormetric native block encryption."

"Automation could be simplified."

"Pure Storage will have issues with positioning in the near future since its a relatively new company. For now, customers need a PoC to trust using the solution, as it can't stand on its brand name alone. They need to improve Pure Storage's marketing."

"What I dislike about Everpure FlashArray is that in the replication, if it is in the pod, we cannot directly add devices to the pod without breaking the relationship."

"FlashArray could improve on the administrative side. For example, when you need to upgrade the boxes, we can't do that ourselves. We need to open a ticket with support and have them do that for us. You don't need to be on the call with them. We tell them we have a slot that we want to upgrade, and they send us an email when it's done."

"I can't see where they can make anything better, unless, of course, they lower their prices even more."

More Everpure FlashArray cons

"If they could introduce a write cache feature, the product would be perfect overall."

"I think ScaleIO already has some features for scalability as it is part of the reason for the product, but in terms of size, maybe they should try to address parent storage."

"There is room for improvement in the area of horizontal scaling."

"It would be nice to set minimum IOPS per volume, besides just the maximum, to be able to satisfy this demand from customers out-of-the-box, not by calculating number of disks, etc."

"Ecosystem around the product: There is no built-in system for viewing history data, such as volume IOPS. We have to provide graphing by Prometheus and Grafana, which would be a good new feature in ScaleIO."

"Anytime I have encountered issues with stability, it usually was the result of a poor design or poor implementation."

"The only thing I can think of at this time is to improve the performance monitoring and performance visibility within the GUI."

"The usability is pretty good but it could use a little tweaking on the UI, with a clearer definition of exactly what some of the things do."

"During some intensive I/O workloads, and on a configuration that had SSDs sub-sized, we reached the limit of the system."

"Some intelligence can be added to the newest version to provide more flexibility between storage tiers."

"Room for improvement would be support for more NVMe-based devices and especially firmware combinations; that's sometimes a problem."

"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."

"We often run out of space but we have enough capacity for memory and CPU. It's difficult to find the balance between storage and memory CPU."

More VMware vSAN cons

Pricing and Cost Advice

"Because of the SSD, it is cheaper because I am not purchasing so many disks."

"We consume it as a service, and that's actually something we really like, or at least I really like from the technical perspective. That's because it means there is no hassle when we need to upgrade arrays to add capacity. We just interact directly with technical counterparts, and we say, "Hey, we're filling up," and they say, "All right, here's another data pack." They ship it in, and we install it. So, the as-a-service model has worked very well. Given the outstanding data reduction rates, it has improved our profitability because we're selling allocated volumes as part of the cloud service or recovering those costs from our tenants. It is very efficient, but that has offset the premium price. It started out that way, but over time, as we've added capacity, the price per gig has gone down a lot because we have a lot of it."

"There are no licensing fees or other costs."

"There is always room for negotiation."

"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."

"The price of the solution is not expensive."

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

"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."

Information not available

"VMware is not a cost effective solution, especially if you have a Microsoft shop. In this case, you would have to purchase the VMware license when there are already Hyper-V solutions that could do it for much cheaper."

"The price of the solution package depends on the nodes and other factors. The cost some of our customers paid was $500,000. The licensing cost for the components is very good."

"The product's price is not high. The tool is available at a normal price."

"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 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."

"It is expensive, but you get what you pay for."

"We pay for a license to use the solution through our company CapEx and then we continue to pay annually."

"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."
