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.

Pros

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

"What I like best about Pure Storage FlashBlade is its object storage functionality, plus it has fast underlying hardware. Pure Storage FlashBlade is also very stable. I find its stability one of its valuable features."

"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 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."

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

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

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

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

More Pure Storage FlashBlade pros

"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."

"DataCore Swarm is highly available."

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

"I find its flexibility valuable."

"Nutanix Volumes is a perfectly stable product."

"The most valuable features are the interface and support."

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

"The availability of the environment is incredible, and with Prism Central, you're able to diagnose and go over issues quickly."

"The biggest return on investment for me when using Nutanix Unified Storage (NUS) is the management aspect since it's easier to manage."

"DR and the replication power are valuable."

"The most valuable features of the solution are replication and backup and our company needs a tool to help us with disaster recovery and the security of our data."

"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."

Cons

"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."

"The speed could be improved."

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

"I would like to see more monitoring capability included in the next release of this solution."

"The documentational aspect of FlashBlade needs improvement."

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

"I would like to see better integration."

"There could be improvements in public cloud integration."

More Pure Storage FlashBlade cons

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

"The solution needs simpler architecture."

"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 interface is not logical. It should be a little simpler."

"The pricing can be quite high."

"I would not recommend Nutanix Unified Storage (NUS) to other users or developers because it does not support fiber channel (FC) or NVMe storage, and only supports iSCSI, which I believe is outdated technology in today's market."

"It could be more user-friendly."

"It is challenging to configure access control settings."

"There is an occasional language barrier between some of the technicians, which can be challenging; however, that doesn't prevent us from being assisted, as they can remote in and use Pulse to view our cluster and gather logs and reports."

"While Unified Storage has evolved a lot over time, its database handling needs to improve a little. There could be an improvement in terms of costs. It's a little expensive for Brazil but still delivers a lot of performance."

"If they can add an integrated DLP feature, it would be great."

Pricing and Cost Advice

"Our customers have seen a reduction in TCO."

"The product is very expensive."

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

"We used a reseller for the purchase."

"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."

"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 pricing for FlashBlade is between cheap and moderate."

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."

"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."

"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."

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

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

"The solution is highly-priced."

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

"The licensing currently works based on a software license. If we have files, volumes, and other licenses combined, that would be more valuable. I don't want to go for a separate license for files and a separate license for volumes. We have unified storage, so the licensing should also be unified. That would be helpful."

"Nutanix Unified Storage pricing is reasonable."
