Featured Reviews

Eric Black

Solutions Architect at Recovery Point Systems

The ability to leverage multi-tenancy along with immutability is a huge benefit for us

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. Veeam Backup specifically has started to streamline their API, and they are doing that with SOS API. They have optimized it. Any of the S3 devices out there that support this SOS API can have far more API calls at once. On our side, that translates to better restoration. With SOS API, it can leverage far more restorations at a single given time or read from the device in simple terms. That results in maximizing the output and throughput from the device itself.

Pricing challenges overshadow efficient data handling and fast deployment

In terms of improvement areas for Nutanix Unified Storage (NUS), pricing is a significant issue, and another aspect is that the export of Nutanix backups does not support CD-ROMs, which is a disadvantage. Currently, it only supports QZ bus types for backups, which limits compatibility. When comparing Nutanix Unified Storage (NUS) with other solutions in the market, it falls short because it only supports iSCSI backups, while competitors also support QZ, iSCSI, fiber channel, and NVMe storage. The solution requires no maintenance for patching since it is designed effectively, but Nutanix Unified Storage (NUS) does not support fiber channel connectivity or external attached storage through NAS, limiting its compatibility. Additionally, technical support response time and efficiency are lacking in comparison to competitors.

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

"It performs well and it is also very fast."

"The initial setup is pretty quick."

"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."

"The performance of FlashBlade is excellent. It does not necessarily leverage the SOS API that some of the newer products leverage, but I found its speed pretty much on par and comparable. It is fast, and it does what it is supposed to do."

"The onboarding and integrated monitoring tools are pretty good."

"The product is scalable and easy to expand."

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

"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."

More Pure Storage FlashBlade pros

"The deployment was very easy."

"Nutanix Unified Storage is easy to use. New employees are able to come up to speed fairly quickly with regard to the day-to-day administration processes."

"Nutanix technical support is excellent, with swift responses based on priority."

"I like Nutanix Prism Central. The primary benefit is that we can manage everything from the same page."

"We transitioned from a three-tier architecture to Nutanix Unified Storage (NUS). With the Files offering out of Nutanix Unified Storage (NUS), we were able to migrate those shares with a smaller footprint."

"The most valuable feature is the unified dashboard, as it allows us to easily observe everything from a single location."

"I rate Nutanix Unified Storage (NUS) a ten out of ten."

"The benefit for our customers is cost effectiveness."

More Nutanix Unified Storage (NUS) pros

"The extreme compression of data is a big thing for us. We were looking for an online backup solution, and QoreStor is very good in terms of data compression. It helps us minimize the required storage in the Blob Storage environment."

"Quest QoreStor definitely saved us money."

"Deduplication is the most valuable feature. It saves us a lot of space. When we back up 100 terabytes of data, after dedupe, it only uses maybe five to six terabytes for the disk space in QoreStor."

"The features we use for the data deduplication are nice because we're able to back up a much larger amount of data, yet it doesn't necessarily take up that much data on the devices."

"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."

"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."

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

"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."

More Quest QoreStor pros

Cons

"The feature that we're waiting on is better integration with the cell services."

"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."

"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."

"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."

"They need better integration with public clouds along with a better hybrid solution."

"Its configuration should be easier."

"I have not seen ROI."

"It's on the expensive side, as expected for a niche product."

More Pure Storage FlashBlade cons

"The pricing could be improved."

"The documentation on the support site needs to be improved."

"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."

"The product needs to work a bit more on its ransomware detection capabilities."

"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."

"There are still some gaps in the solution's synchronization that could be improved."

"The solution needs to be more open to integration with other vendors. Sometimes, we struggle with the support process. Our skilled engineers must explain our problems to everyone, even though we've already done preliminary investigations. The support team follows standard procedures, which can be painful. We're not a small customer, especially in the life sciences sector, so we'd appreciate more specialized support. I've heard Nutanix Unified Storage has teams dedicated to life sciences and healthcare; we should be part of that."

"When considering the difference in cost benefits, if you consider it only as a storage solution, you may find it expensive."

More Nutanix Unified Storage (NUS) cons

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

"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something. So that when we don't do a backup, we want the QoreStor to stay offline. It would be a nice feature to have."

"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."

"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."

"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."

"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."

"The ransomware protection of QoreStor could use improvement."

"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."

More Quest QoreStor cons

Pricing and Cost Advice

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

"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 pricing for FlashBlade is between cheap and moderate."

"Our customers have seen a reduction in TCO."

"The product is very expensive."

"The price could be cheaper."

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

"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."

More Pure Storage FlashBlade pricing and cost advice

"Licensing-wise, I have no complaints. Their license is pretty simple and easy. It gives us everything we need, so I have no complaints about licensing."

"Nutanix Unified Storage is competitively priced. There aren't any competitors that can do much better for the same price."

"It's definitely a lot cheaper than buying a new EMC array. We bought a five-year commitment on all the hardware and software. I don't know what the cost was back then, but I do remember it was cheaper."

"The price can always be improved. As a customer, you always seek reasonable solutions within your budget, and they give us little to do a lot. My IT team always has to justify that we are choosing an optimal solution, so the price could be a little lower Maybe the prices could be a little bit lower."

"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 price of the license is expensive when comparing it to traditional storage."

"With all of the Nutanix equipment, the licensing is expensive. We operate in the enterprise space, but we're a midsized company. At times, the price tag is a little bit shocking for a company with only 35 employees. We're not a Fortune 500 company, but we deal with Fortune 500 drug and energy companies. We have to play in that enterprise space if we're going to have enterprise customers. I'm very price-conscious, but I understand that if I want the best, I've got to pay the price."

"I'm happy with the cost and licensing because I don't have big volumes."

More Nutanix Unified Storage (NUS) pricing and cost advice

"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."

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