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

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

"The solution provides many controllers."

"The product is scalable and easy to expand."

"It uses the same platform for connectivity so integration is seamless."

"The most valuable feature of this solution is performance."

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

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

"We have seen a reduction in the total cost of ownership by around 20%."

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."

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

"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."

"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."

"We migrated over to Nutanix and saw an immediate improvement in the performance."

"The most valuable features of the solution are high availability and synchronization to another location."

"Nutanix Objects is reliable."

"The pricing, setup costs, and licensing of Nutanix Unified Storage (NUS) are amazing, in my view."

"I would recommend Nutanix Unified Storage. It's easy to use, and they are the best when it comes to storage services."

"The initial setup is pretty straightforward. With a few clicks, you can stand up your storage. It reduces the overall life cycle of deployment within the ecosystem."

"We have virtually zero downtime with Nutanix. It updates itself, and we can easily move machines from one cluster to another."

"I strongly recommend Nutanix Unified Storage (NUS) to all users as a modern cloud computing system, offering significant cost savings for clients, customers, and vendors while providing excellent cloud infrastructure operations."

Cons

"Its configuration should be easier."

"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."

"There could be improvements in public cloud integration."

"I would like to see the licensing fees improved as well as the price per terabytes."

"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."

"The speed could be improved."

"The features provided for SMB customers are limited."

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 solution needs simpler architecture."

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

"The pricing can definitely be better."

"The dashboard could be more customizable"

"I think Nutanix Unified Storage (NUS) can be improved with integration with vendors other than VMware or Dell, seeking more integrations with other storage vendors."

"When it comes to Nutanix Files, one thing that would be great is a slightly easier way of managing snapshots and restore points, especially when a third party is involved."

"There is no tagging concept in Nutanix Unified Storage where you can tag the servers."

"Pricing can always be better."

"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 should improve the one-click upgrade. There are a lot of dependencies on third-party licenses and HP hardware we use internally. The one-click upgrade fails sometimes."

"The feature request I have is for the consistent improvement of how user account permissions are assigned in Nutanix Unified Storage."

More Nutanix Unified Storage (NUS) cons

Pricing and Cost Advice

"The price is a little high."

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

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

"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."

"The product is very expensive."

"Our licensing is renewed annually."

"The price of this solution could be made more affordable."

"Our customers have seen a reduction in TCO."

More Pure Storage FlashBlade pricing and cost advice

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

"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"

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

"The cost of Nutanix Unified Storage can be prohibitive for some small and medium-sized businesses, making it challenging for them to adopt the product."

"Nutanix Unified Storage pricing is reasonable."

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

"I am not the one who makes the calls, but it seems to me that it was very competitive. Other solutions would have required dedicated hardware, so an additional CapEx has to be put in place. In that sense, it was definitely a more competitive option to go with Nutanix Files."

"The solution's pricing is fair."

"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."

"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."
