MikaelHellström

IT Manager at Regin Dalarna

Has handled backup storage needs reliably and supports seamless upgrades

In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

Amarnath Charugundla

System Engineer at Tata Consultancy

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.

Jeff Manuszak

CTO at EDSI

Cost-efficient, highly scalable, and installable on different types of hardware

They could improve on support a little bit. We have not had to engage their support much, but when we do have issues, it can take longer to get things resolved. We are pretty lenient as we do a lot of IT support ourselves. We are not very hard on support organizations, but when a customer has a support issue, it would be easier if the support processes were a little bit more automated. It would be beneficial to have an easier way to upload diagnostic dump files. They can make it easy for the customer to collect the diagnostic data. There can be some kind of monitoring solutions to alert users to issues with the appliance or software, making it easy for customers to monitor their systems in the field. This is especially critical because it stores customers' backups, and a failure can have significant business impacts. If a customer does not have the backups and has a disaster, they can be out of business, so monitoring is key.

Quotes from Members

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

Pros

"The initial setup is pretty easy and simple."

"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."

"Among its most appealing features are its ease of handling and minimal maintenance requirements."

"The main feature I have found to be product replication."

"Pure Storage FlashBlade's scalability is one of the most valuable features, and importantly, it always works, allowing for seamless upgrades."

"The initial setup is pretty quick."

"The solution provides many controllers."

"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."

More Pure Storage FlashBlade pros

"What I appreciate about Nutanix Unified Storage (NUS) is that we have faced several issues in the Unified Storage, the compression and deduplication features have worked exceptionally well in the Unified Storage, and it has helped my business as it operates seamlessly without any interruption."

"The solution is simple and robust."

"We can utilize mixed storage block-sized objects and combine various databases within a unified interface."

"It is unified. This is the best thing that Nutanix gave to the world. You can do everything from one point."

"Based on my experience, I rate Nutanix Unified Storage (NUS) ten out of ten."

"Nutanix's analytics provide better insights into all of our files."

"Nutanix Unified Storage (NUS) is very fast in terms of migration and data access with respect to VM, OS, and storage, experiencing a 30% faster performance compared to VMware."

"What I found most valuable in Nutanix Files Storage is its high availability and ability to scale out with many VMs."

More Nutanix Unified Storage (NUS) pros

"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."

"This software solution can be installed on many different types of hardware, which makes it very flexible. We can run it on virtual machines or virtual servers, providing convenience for solutions of varying sizes, from small to large."

"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."

"The dedupe and compression are pretty extreme. On disk, we're getting dedupe rates of up to 65 percent of data and compression of 34 percent. When you go to the cloud, it's more like 76 percent for dedupe and almost 50 percent for compression."

"Quest QoreStor definitely saved us money."

"We need revisions and safe backup so that it could be held up in court, but deduplication and compression are the main features why we have Quest QoreStor. That's where it really shines. I use ZFS and XFS at home, and Quest QoreStor is even better."

"Quest QoreStor is very stable compared to our previous solution."

"QoreStor has helped us to reduce our backup storage requirements on-premises. We've been using the same devices for quite a while, and so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution. The advantage here is even if we had to retire the hardware tomorrow, the QoreStor part doesn't change. We just have to have additional hardware and put the solution back on whatever hardware we pick and it'll do the same thing."

More QoreStor pros

Cons

"The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top."

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."

"I would like to see more monitoring capability included in the next release of this solution."

"I would also like to see better support for CIFS workloads."

"I have not seen ROI."

"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."

"The speed could be improved."

More Pure Storage FlashBlade cons

"We would love to see the analytics and ransomware protection extended beyond just file servers to virtual machines, but they have a different product that covers that."

"I would like Nutanix to provide a solution for virtual disks. This is the main problem for which we want a solution."

"Managing other storage infrastructure on Nutanix Files Storage is an area for improvement. In particular, I want to add other forms of storage from different vendors not currently in Nutanix Files Storage, to the file server, for better management."

"There should be more automation. Going deeper, I would appreciate seeing out-of-the-box automation for storage provisioning and maybe some more customer-facing, web portal-type or API functionality to Jira or ServiceNow."

"For me, personally, it's a little bit slow because there's so much stuff in the underlying layers that even after talking with Nutanix support, I couldn't really grasp it."

"The integration feature with Nutanix Unified Storage (NUS) could be improved, maybe into a more stabilized version."

"There are some processes, like if I like to change the data storage to another place, I have to use CLI, and I don't like it since I believe that it could have been simpler in GUI."

"Security is an area for improvement. When there are vulnerabilities, there needs to be a faster approval process. The solution needs to automatically target the vulnerabilities and not waste too much time."

More Nutanix Unified Storage (NUS) cons

"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."

"The setup of the software is definitely not the easiest thing. I worked a lot with Quest engineers, especially in the early days when we were first testing it and trying it out. I actually had some of the developers working with us at one point because they were going through these point releases, and I was having trouble getting it to work in this S3-compatible situation. We got it all working eventually, but setup is definitely not the easiest thing in the world."

"They could improve on support a little bit. We have not had to engage their support much, but when we do have issues, it can take longer to get things resolved."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial. After everything is set up and configured, there should be a way to export the configuration. In case something happens to the QoreStor server, and we need to reinstall and configure everything, being able to import the configuration would be helpful. This feature does not currently exist."

"The importance of support is significant to me. I was working for a service provider, and all of our customers had a Quest or warning. Sometimes the support really underperforms."

"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable. You have to have a connection to support to install."

"The ransomware protection of QoreStor could use improvement."

More QoreStor cons

Pricing and Cost Advice

"I feel that the price could always be lowered."

"The product is very expensive."

"Our customers have seen a reduction in TCO."

"We used a reseller for the purchase."

"Our licensing is renewed annually."

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."

"The price could be cheaper."

More Pure Storage FlashBlade pricing and cost advice

"Nutanix is priced a bit higher than some of its competitors. A lot of Chinese companies like Huawei are entering the Saudi Arabian market trying to provide similar solutions for a lower price. It offers a good value, especially the support. Nutanix has a highly competent team. The after-sales support is excellent."

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

"Its pricing is good to okay. It is not super inexpensive, but it is still competitive. Everything could always be lower."

"The product has an annual licensing fee."

"Nutanix Unified Storage was cheaper than other solutions we evaluated."

"The solution's pricing is fair."

"It is competitive with other vendors, but you get more for your dollars. It is fairly priced, but not cheap."

"I find Nutanix Files Storage competitively priced, even its feature set. Its price is seven out of ten."

More Nutanix Unified Storage (NUS) pricing and cost advice

"Quest QoreStor's pricing is affordable. We evaluated Veeam, a well-known company for backup solutions, but found their pricing to be quite high. Veeam's price was almost double. For us, Quest QoreStor is very affordable."

"The pricing is good. It is competitive for a managed services provider. I like the ability to pay by the terabyte, allowing for an incremental cost that we and our customers can afford, so the solution grows with the customer."

"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."

"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
