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.

Sales Manager at MSDSYSTEMS S.R.L.

Has simplified data protection across two locations and reduced time spent on recovery efforts

The best features DataCore Swarm offers are its scalability and the ability to truly solve many problems related to data loss and recovery. It is important because if we want to add a new code, it sets itself up from scratch, and if we want to add, for example, a 72 terabytes or petabytes node, we just drop it in, which is very easy. DataCore Swarm has positively impacted my organization through the support for my dedicated salespersons.

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.

Quotes from Members

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

Pros

"Speed and ease of use are the two most valuable features."

"The initial setup is pretty easy and simple."

"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."

"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."

"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."

"We can capacity plan at a greater level than we used to."

"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."

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

More Pure Storage FlashBlade pros

"The ability for the solution to use any new hardware quickly and without administration is a great thing in the context of hosting."

"DataCore Swarm is highly available."

"The best features DataCore Swarm offers are its scalability and the ability to truly solve many problems related to data loss and recovery."

"The first feature is compatibility with the S3 protocol. DataCore SWARM allows you to quickly have an on-premise, robust and scalable environment that is natively compatible with the S3 protocol. The functionalities used are therefore derived from the S3 protocol, notably versioning and therefore the possibility of configuring immutability in governance or compliance mode. The object metada can be enriched with the addition of tags to subsequently enable filtering and searching. Configuring and using DataCore SWARM is simple and flexible. It is very easy to create domains, tenants and buckets for different use cases with various authentications. The cluster architecture also allows replication between different clusters at different configured levels (Cluster / Domains / ...) A web interface for browsing the content of existing buckets allows simple and rapid manipulation of certain objects such as sharing via a link or cropping a video. Finally, the physical architecture of the solution is based on an x86 server and its scale-up or scale-out evolution is very simple by adding disks or servers."

"I find its flexibility valuable."

"With DataCore Swarm, we have transitioned from tape-based backups, which were long, to Swarm, making the process more rapid and efficient."

"The solution is easy to use, share, and manage."

"The most valuable feature of Nutanix Unified Storage is redundancy."

"What I like most about Nutanix Files Storage is the way it makes copies of the data. The solution also has high availability, which is excellent. Another valuable feature of Nutanix Files Storage is self-service, so users won't have to depend on the IT team much."

"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."

"The reliability and availability are the most valuable features. Reliability is important because it can run my workloads. I need to be able to take advantage of the VMs that are executing on the storage. It has to be reliable. It's also important to have the storage available for scaling VMs on demand."

"The solution is simple and robust."

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

"Redundancy and availability are valuable. We have several nodes, so it stays up, and there is redundancy. Then there is availability."

More Nutanix Unified Storage (NUS) pros

Cons

"Commvault has mainly driven the Analytics, providing data and reports. However, the product has room for improvement, especially regarding storage analytics. Upgrading firmware has caused issues, requiring feature disabling to revert to traditional backups. The firmware upgrades sometimes affect Commvault backups."

"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."

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

"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."

"Its configuration should be easier."

"In my opinion, one way Pure Storage FlashBlade can be improved is by having more compatibility between the FlashArray and FlashBlade, allowing for synchronized data between both platforms."

"Its configuration should be easier."

"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."

More Pure Storage FlashBlade cons

"The product currently requires a significant number of servers to start. There are also network prerequisites to be met in order to guarantee good security of the architecture, which means that the product is only available to large customers. Besides, the license starts at 100TB. An Appliance version is being developed with an architecture based on containers which will make it possible to offer DataCore SWARM to everyone. The product has been evolving since the acquisition by DataCore, but maintaining and updating the product is not always easy and needs to be improved. For now, we only use DataCore SWARM for a few use cases and therefore a small part of the existing functionalities. With use we will perhaps have more criticism of the product but not for the moment!"

"The main issue currently is the hard installation process."

"The pricing can definitely be better."

"The main issue currently is the hard installation process."

"The solution needs simpler architecture."

"The CVM consumes more memory and CPU, as it will be allocated a minimum of 32 GB. For a large data store, they are unnecessarily consuming extra resources through the built-in CVM."

"Nutanix Unified Storage (NUS) needs improvement, particularly for firmware upgrades, as sometimes updates take a whole day and it can be unclear whether the issue is with Nutanix Unified Storage (NUS) or the hardware, requiring us to reconfigure everything, which is a main point we want consolidated into one solution."

"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."

"We couldn't access Nutanix Unified Storage (NUS) from Prism Central due to bugs. The bugs that Nutanix fixed in newer versions prevented us from accessing Nutanix Unified Storage (NUS) from Prism Central."

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

"Requires higher upfront investment"

"Lowering the price would improve this product."

"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."

Pricing and Cost Advice

"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."

"Our customers have seen a reduction in TCO."

"The price is a little high."

"I understand that it is competitively priced compared to other brands."

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

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

"The product is very expensive."

"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

"You pay for what you use. For example, if you use one terabyte, you just pay for that one terabyte. But the pricing could always be better"

"The first installation brick is expensive but the upgrades are extremely simple and granular by adding disks or nodes."

"My company is in Brazil, and making the payments in dollars is tough for our organization."

"The pricing is a bit too high."

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

"If we compare the cost of Nutanix Objects Storage to other solutions such as VMware licenses, our current choice is Nutanix Objects Storage. This solution is more cost-effective. However, adding VMware to Nutanix would not be a cost-efficient decision, which is why we do not use it anymore."

"Nutanix offers different pricing options, including Ultimate and Ultimate Pro."

"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."

"Nutanix is very competitive."

"The pricing is fair."
