Senior Network Engineer at Holy Redeemer Health System, Inc.

High performance and throughput enhance IT backup management

The multi-dimensional scale-out design feature of Pure Storage FlashBlade is not in use in our environment. Regarding data reduction technologies, we don't get much deduplication because the data is already deduplicated from our FlashArray before we get to backup, so there is no benefit of deduplication. Regarding the integration with cloud-native ecosystem tools, we are not on cloud; we are strictly an on-premises solution. Pure Storage FlashBlade is not used by any end-user; it's used only for IT backup, with only about four people in our group managing it. I cannot recommend Pure Storage FlashBlade to other users depending upon their financial situation because it's an expensive solution, and the cost is very high, including licensing and renewal every year. I rate Pure Storage FlashBlade an eight out of ten.

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

"I would rate Pure Storage FlashBlade a ten out of ten."

"It's very easy-to-use."

"The most valuable features of this solution are the rewrite speed and the nonstop services."

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

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

"The most valuable features are the Metro clustering, and disaster recovery."

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

"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

"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."

"DataCore Swarm is highly available."

"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."

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

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

"It gives more security that the data isn't going to get lost."

"The capacity is very good. They use fewer nodes than before. Each node is isolated with the CPU with the performance. It is a cluster node but works separately, so the performance will be tripled."

"What I appreciate most about Nutanix Unified Storage (NUS) is the efficiency in terms of storage capacity and reuse."

"It's a centralized place for management. With all our virtual machines and Kubernetes in there, it's a single place to manage all of our resources, instead of having to jump around to different places."

"The solution is stable and extremely easy to calibrate."

"My experience with pricing, setup costs, and licensing of Nutanix Unified Storage (NUS) is that compared to other vendors, Nutanix is very reasonable."

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

"Nutanix Unified Storage is a simple, user-friendly, and stable solution."

More Nutanix Unified Storage (NUS) pros

Cons

"I have not seen ROI."

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

"I would like to see better integration."

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

"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."

"The speed could be improved."

"The documentational aspect of FlashBlade needs improvement."

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

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."

"What's missing in Nutanix Files Storage is the support for multiple intranets or VLANs on the same file from different networks and network devices."

"The graphical user interface could provide more detail. It would be nice if we could click on the service and get some expanded definitions of them. When hiring new people, it's difficult to teach them how everything works, but if they can access everything, they can teach themselves."

"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."

"Nutanix needs to improve their cybersecurity options at the storage level."

"The biggest thing for me, which is a pet peeve of mine, is the integration with the hardware platforms."

"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 interface could be improved."

"Nutanix Unified Storage (NUS) needs improvement in compatibility with Windows solutions."

More Nutanix Unified Storage (NUS) cons

Pricing and Cost Advice

"Our customers have seen a reduction in TCO."

"I rate the tool's pricing a seven to eight out of ten."

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

"Our licensing is renewed annually."

"We used a reseller for the purchase."

"The pricing for FlashBlade is between cheap and moderate."

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

"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."

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."

"It is quite expensive otherwise as it comes with three-tier peer underlying hardware."

"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."

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

"The solution is highly-priced."

"While the price may not be the most affordable, I believe it offers good value for the benefits it provides."

"Nutanix Unified Storage pricing is reasonable."

"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."

"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."
