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.

Hyper-converged storage has improved performance and now supports high redundancy for our VMs
Nutanix Cloud Infrastructure (NCI) was transparent because we were on a regular infrastructure before. We went on NCI and were able to improve performance, but it did not really change how things worked. The performance was really better for applications and access times to the data. I regularly looked at the analytics to see what was going on in my servers and what it was saying to optimize performance. It was pretty interesting because it could analyze and give insights on how to get things working better. In the latest versions, the Prism interface has been replaced by Prism Central. This requires another machine to be deployed to manage the servers.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It allows engineers to focus on other things rather than doing the more manual tasks. It automates tasks, so the ease of use is extreme. It simplifies the storage."
"We clearly have seen the difference between having storage on Dell EMC or NetApp versus what we have now on Pure Storage, and the investment was a clear win for us."
"The initial setup was straightforward in the way that it was a database vacuum storage."
"This solution has improved our organization in the way that we used to see latency but now with this solution we don't. It also has good performance. Latencies have come down for our performance in the SQL databases. We can put a lot more in a lot less in terms of space savings. We also save data center space have good deduplication."
"We put a fair amount of stress on it because we run sequel workloads and we run web applications where the same web files are hit over and over, and we have had almost zero stability issues with that SAN, which has been really great for us."
"The stability of Pure Storage is very very good."
"The initial setup is very straightforward. You simply plug it in and turn it on."
"It's easy to use, and the maintenance upgrades to get free controllers work really well."
"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."
"The most valuable feature is the robustness, which is typical of IBM because their software generally just works."
"Implementing this solution has been a very good decision for our in-house data center."
"The management interface of this solution is great."
"It is easy to use. One of the things they have as a design goal is to reduce complexity and simplify things."
"Best features are around data locality, compression, and deduplication."
"It has seamless expandability."
"Simplicity is very, very important, and I think Nutanix gives you that comfort when you do the right sizing and implementation."
"Each performance test with SQL, Exchange, Oracle, or SAP is better than on a three-tier architecture."
"Acropolis could help us build a cloud environment for our company."
"It supports multi-cloud integration that includes AWS, Google, and Azure."
 

Cons

"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"During heavy load situations with 100K IOPS on one specific port, it requires more granularity level for distribution."
"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."
"There are many features which need to be added, particularly on the replication side."
"In the next release of the solution I would like to see Vormetric native block encryption."
"When creating a support case, visibility should be extended to others involved in assisting."
"I would like FlashArray to add reports that help us forecast our predicted resource needs based on current usage."
"Pure will probably have to move to other layers of the stack, not only storage but, maybe, hyperconverged."
"The interface is not user-friendly so the ease of use could be improved."
"The reporting mechanisms need improvement."
"It is not as tolerant as other systems, especially in hardware, if hardware faults often occur."
"We ran into an issue as a managed service provider because Acropolis isn't designed to be used the way we are running it."
"Nutanix Cloud Infrastructure can be improved in terms of the sizing of the solution."
"In terms of what I would like to see improved, I would say the life cycle management. I don't know if it is because they changed to an LCM from the previous way of upgrading the hardware or software but sometimes it feels that it needs a wizard that says, "Check this, check this," telling you your options. The only thing that's a bit frustrating for me is the life cycle management interface. That's the only thing on the entire system that frustrates me."
"Nutanix Acropolis AOS could improve by adding some NAS features, similar to the ones that are available in the NetApp solution."
"The ability to create clusters faster would be nice to see in a future release."
"Notifications could be improved as they're not currently very useful."
"The solution is about 70% stable."
 

Pricing and Cost Advice

"The price is very reasonable when compared to other solutions."
"Pure is typically more expensive than everyone else. You get what you pay for, but I have lost deals to similar solutions because of pricing. They include everything, and that's another positive about Pure Storage. They aren't trying to nickel and dime their customers for different features. It is all included in one price. The license is by capacity, and the price depends on the capacity and the discount we're getting from the vendor. You get the SKU of the physical appliance, support, and maintenance, and that's it. You're licensed for whatever feature they offer. It is all rolled up into the price of the appliance."
"It's a good price point and it's a solid product for the price."
"The pricing is an issue. However, being all-flash, it will always be sort of expensive."
"I don't know the exact cost but it's around $1,000."
"The cost has room for improvement."
"The price was more favorable than Dell EMC."
"We have an Evergreen Storage subscription, which I think is a great feature."
"If you are cost-sensitive then this solution is not for you."
"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."
"It is slightly more expensive compared to a standard, on-prem, bare-metal configuration. There is about a 30 percent overhead there."
"They offer multiple tier licensing which means that lower level licensing will have less features."
"The basic license that comes with the box allows basic virtualization features but advanced automation features would require an upgrade of licenses."
"I would rate the price seven out of ten with ten being the most expensive."
"Nutanix Cloud Infrastructure is expensive."
"Nutanix Cloud Infrastructure's pricing is higher now."
"We renew our license on a yearly basis and have no costs in addition to the standard fee."
"The pricing is fair for the package."

Nutanix vs. VMware EVO:RAIL vs. FlexPod
Originally posted at www.storagegaga.com/dont-get-too-drunk-on-hyper-converged/ I hate the fact that I am bursting the big bubble brewing about Hyper Convergence (HC). I urge all to look past the hot air and hype frenzy that are going on, because in the end, the HC platforms have to be aligned…
