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.

Enhancing backup speed and efficiency with high availability

We use DataCore Swarm essentially for backups, utilizing immutable backups and dynamic archiving from the file server. We also have a project called the Fiservo, which allows us to move the archive and all files from Fiservo It is more rapid than using tape for backups, which was quite slow for…

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 ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."

"The most valuable feature is Safe Mode."

"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 tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."

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

"It helps simplify our storage, because the user interface is very simple and the installation is easy."

"The solution provides many controllers."

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

More Pure Storage FlashBlade pros

"DataCore Swarm is highly available."

"I find its flexibility valuable."

"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 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 simplicity of management is valuable because, in more traditional environments, the platform updates are much more complex."

"Currently, the most valuable aspect of our Nutanix implementation is its file storage functionality."

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

"For somebody like me who grew up building what others call three-tier and I call traditional architecture, the valuable thing is that you can now buy it. You can have new deployments and infrastructure up and running with very little infrastructure behind it."

"The benefit for our customers is cost effectiveness. The customer is spending substantial money refreshing NetApp storage. We identified a use case from a NAS point of view. Using Nutanix Unified Storage (NUS) helps in reducing costs, as they are not spending a dedicated cost for storage procurement."

"Nutanix has excellent product documentation available on their portals, written in simple, easy-to-understand language."

"On a scale of one to ten, I rate this solution a seven."

"The scalability, data redundancy, and security are valuable."

More Nutanix Unified Storage (NUS) pros

Cons

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

"I would like to see better integration."

"It would be nice if you could store file-based in the same box with the same technology."

"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."

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

"The features provided for SMB customers are limited."

"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."

"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."

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 solution needs simpler architecture."

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

"Its features can be further enhanced from the DR and high availability points of view to match other vendors, such as NetApp."

"We have issues with software updates occasionally."

"Unified Storage failed to fulfill our object storage requirements."

"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."

"Lowering the price would improve this product."

"Improving quota policies would be advantageous, particularly by offering the option to implement blocking instead of just issuing warnings."

"It's still pretty expensive."

More Nutanix Unified Storage (NUS) cons

Pricing and Cost Advice

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

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

"Our customers have seen a reduction in TCO."

"The price is a little high."

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

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

"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."

"Licensing fees are paid yearly."

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 pricing is a bit too high."

"The pricing is fair."

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

"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."

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

"We are Nutanix partners, so it is pretty good. With the free terabyte that comes with the Nutanix clusters, we have started to build proposals for the clients. The price adjustment with the new policy of Nutanix Unified Storages seems attractive. Let us see if it has results."

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