Sowjanya MV

Technical Lead at Wipro Limited

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 management and cost-effectiveness lead to positive experiences and future savings

Improvement is necessary wherein the memory or storage should not breach 90%, because if breached, it becomes unmanageable. We have to set alerts or CPU triggering for 95% for the first warning. Other activities on nodes or file systems should be properly maintained. We must monitor the dashboard for P1, P2 alerts in the Nutanix Unified Storage (NUS) file share system including SMB, NFS, objects, and blocks. Attention should be maintained for any alerts such as CPU, memory, and RAM alerts, as exceeding these creates issues within teams. If triggered to 95% and forgotten, it crosses the SLA breach, causing disturbances to application, web, and platform teams. Continuous monitoring on the Nutanix dashboard is essential. Even a highly experienced person in Nutanix Unified Storage (NUS) cannot provide a 10 rating out of 10 because it is a vast system. I would rate it eight from my perspective.

A nicely-done product that provides a lot of graphs and reports to see what's happening in the background and makes configuration easier

It's very well done for what it's supposed to do, and I don't have anything to add, but I would like them to keep it available to the public. SwiftStack is going out of the market. NVIDIA purchased SwiftStack a couple of years ago, and they won't be making it available to the public anymore. Our license is up to March 31st.

Quotes from Members

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

Pros

"The connections are a lot faster than what we had in the past. One InfiniBand does what we did on all of our Fibre Channels."

"It's just very easy for general block storage."

"It overperforms both in terms of storage capacity and throughput, and bandwidth capability."

"The most valuable features are the replication of data and the continuous snapshot that we can take from the disc."

"Provides fast access and is user-friendly."

"We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years. It simplifies storage for us."

"The initial setup was straightforward in the way that it was a database vacuum storage."

"Having an intuitive user interface to get things running is great."

More Everpure FlashArray pros

"The scalability, data redundancy, and security are valuable."

"The scalability, ease of use, and technical support are the most valuable features of Nutanix Unified Storage."

"For customer service and technical support, I would rate them a nine out of ten."

"Nutanix Objects is reliable."

"The benefit for our customers is cost effectiveness. The customer is spending substantial money refreshing NetApp storage. We identified a use case from a NAS point of view. Using Nutanix Unified Storage (NUS) helps in reducing costs, as they are not spending a dedicated cost for storage procurement."

"The most valuable features are the interface and support."

"I strongly recommend Nutanix Unified Storage (NUS) to all users."

"The biggest advantage we find with Nutanix Unified Storage (NUS) is the performance, due to it being hyper-converged and using all-flash nodes. The storage is very responsive, and it's significantly easier to manage from the Nutanix Files platform that comes along with NUS Pro."

More Nutanix Unified Storage (NUS) pros

"The most valuable feature is its versatility. We use 1space and we can use it for almost anything: for our cloud service, for backups of VMs."

"The performance is good. It is a secondary storage platform designed for archive and backup, so performance for the right use cases is very good. We have been pretty happy in that regard."

"The biggest feature, the biggest reason we went with SwiftStack, rather than deploying our own model with OpenStack Swift, was their deployment model. That was really the primary point in our purchase decision, back when we initially deployed. It took my installation time from days to hours, for deployment in our environment, versus deploying OpenStack Swift ourselves, manually."

"In terms of the hardware flexibility, with SwiftStack not being a hardware company, I literally buy any hardware that's the least expensive, from any vendor... from a flexibility standpoint, I think it's fantastic. I can go to anybody, anywhere - any vendor - and get my hardware."

"The graphs are most valuable. They have a lot of graphs and reports that you can run to see what's happening in the background to configure OpenStack Swift."

"The general consensus on what we've done is that the restores coming back from it have been faster than they were from our prior vendor. Ingest speeds are fine. The restore speeds have improved."

"The scalability is phenomenal. It seems infinite, as long as you put enough storage in place, add enough nodes."

"The SwiftStack Controller, which is the web UI, provides out of band management. This has been one of the best features of it. It allows us to be able to do upgrades and look at performance metrics. It is a top feature and reason to choose the product."

More SwiftStack [EOL] pros

Cons

"They can also include file services such as NAS shares and CIFS shares. There should be provisioning of the file shares from a unified array."

"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."

"The initial setup was a little complex. We had some initial issues with the design and had to help correct some of the white papers for it, but it wasn't your standard use case."

"We would like to integrate it more with our backup solutions."

"As long as they always improve on IOPS speed, that's all we're really looking for. The faster the storage can be the more we can do speed of application and speed of use."

"If they could make it cheaper, that would be something."

"I would like to see data tiering to AWS."

"The 3PAR SSD arrays that we have are still failing a lot so even though we're under warranty, we still have to get someone out and usually have someone troubleshoot so that usually adds onto the cost. With Pure, we've had a disc fail and we pop it out and you pop it in and it's good to go."

More Everpure FlashArray cons

"A more consistent flow of information would improve the solution, as I've noticed some inconsistencies, mostly stemming from the coordination between the hardware vendor and Nutanix."

"The training programs could be improved. It's quite challenging to find adequate learning resources online, as there isn’t much available on the internet or YouTube."

"Nutanix Unified Storage (NUS) can be improved involve the limitations I've seen in Files Analytics, specifically to the number of FSVMs today that File Analytics can analyze."

"The dashboard could be more customizable"

"It could be more user-friendly."

"There is some confusion in the reporting when I have to create the report for statistics. I find it is not so user-friendly."

"Areas for improvement in Nutanix Unified Storage (NUS) include more redundancy to ensure no data loss, and balancing the workloads is very important to maintain managed workloads throughout the year."

"Nutanix could improve the ability to track user actions, such as identifying who deleted a folder."

More Nutanix Unified Storage (NUS) cons

"[One] thing that I've been looking for, for years as an end user and customer, for any object store, including SwiftStack, is some type of automated method for data archiving. Something where you would have a metadata tagging policy engine and a data mover all built into a single system that would automatically be able to take your data off your primary and put it into an object store in a non-proprietary way - which is key."

"They should provide a more concise hardware calculator when you're putting your capacity together."

"I would like to see better client integrations, support for a broader client library. SwiftStack could be a little bit more involved in the client side: Python, Java, C, etc."

"The biggest room for improvement is the maturity of the proxyFS solution. That piece of code is relatively new, so most of our issues have been around the proxyFS."

"At the moment we are using Erasure coding in an 8+4 setting. What would be nice is if, for some standard configurations like 15+4 and 8+4, there were more versatility so we could, for example, select 8+6, or the like."

"It's very well done for what it's supposed to do, and I don't have anything to add, but I would like them to keep it available to the public. SwiftStack is going out of the market. NVIDIA purchased SwiftStack a couple of years ago, and they won't be making it available to the public anymore. Our license is up to March 31st."

"The file access needs improvement. The NFS was rolled out as a single service. It needs to be fully integrated into the proxy in a highly available fashion, like the regular proxy access is. I know it's on the roadmap."

"Management UI can be improved and have more functionalities."

More SwiftStack [EOL] cons

Pricing and Cost Advice

"The pricing of Pure Storage is all-inclusive. It is very fair, and very easy. In comparison, Dell EMC has licensing that needs to be added if you wan to work in a complex environment or in specific functionalities."

"The Evergreen Storage subscription is great, because then I get new controllers every three years."

"We have seen a reduction in total cost of ownership (TCO)."

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

"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."

"Cost-wise, it's been very effective."

"It is a more expensive solution, but it is worth it. You are getting what you paid for."

"All storage is expensive so any price improvement would help."

More Everpure FlashArray pricing and cost advice

"In the manufacturing industry, we operate under very lean principles where costs are heavily scrutinized. There was some initial hesitation, but the performance we've experienced since switching to the Nutanix platform, along with the peace of mind from having confidence in our platform to not give us issues that keep us up at night, has smoothed over much of that scrutiny."

"It's not the cheapest solution. It's in line with other solutions, but it offers features that the competitors don't have at any price point, especially with regard to analytics and ransomware prevention. No one else has any sort of object-based storage available. Nutanix Unified Storage is a lot more feature-rich. This is a situation where you get what you pay for."

"The product has an annual licensing fee."

"The licensing currently works based on a software license. If we have files, volumes, and other licenses combined, that would be more valuable. I don't want to go for a separate license for files and a separate license for volumes. We have unified storage, so the licensing should also be unified. That would be helpful."

"The product is pricey."

"The pricing of Nutanix is generally higher compared to other vendors, which is a common observation, but it provides value through its support and features offered to customers."

"Nutanix Unified Storage pricing is reasonable."

"For clients running Nutanix, the licensing cost for Files is a small add-on cost."

More Nutanix Unified Storage (NUS) pricing and cost advice

"Dollar per gigabyte, it costs us more because we are storing more. However, if you look at it from a cost per gigabyte perspective, we have dropped our costs significantly."

"We find the pricing rather steep. Of course, you get quality for your money, that's absolutely true... [But] when you look at the prices of the licensing and the prices of your hardware, it's quite substantial."

"We have had a 40 to 50 percent reduction in CAPEX on the acquisition of new hardware, which is probably conservative."

"The pricing and licensing are capacity-based, so it's hard to put my finger on them, because so many different vendors charge in different ways. We are still saving significantly over any of the other options that we evaluated because we can choose the best hardware at the best price, then put SwiftStack software on it. So, it's hard to complain, even though a part of me goes, "It would be nicer if it were less expensive.""

"COST_SAVING; We have had a 40 to 50 percent reduction in CAPEX on the acquisition of new hardware, which is probably conservative."

"All in, with hardware and everything else - and I hate to say a dollar amount because it's been awhile since I computed it - I know I'm under the $300 to $500 per terabyte mark. I call that my "all in" price, which has replications built in and protections built in."

"The pricing model is great and makes sense. We have talked about how to get into more of a frequent billing cycle than once a year. That would be an interesting concept to add into the product, having the ability to have monthly billing instead of having to do a one-year licensing renewal. However, the way the license works by charging for storage consumed is definitely what makes them the most competitive."

"We are able to dynamically grow storage at a lower cost. We can repurpose hardware and buy commodity hardware. There is a huge cost savings, on average $100,000 a year compared to traditional storage for what we have at our size."
