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.

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.

Achieving seamless cost-saving implementation with exceptional support

Pre Post Sales Engineer at Logiccomputer

The best features that StarWind Virtual SAN offers include the price because comparing to other virtual SAN solutions, this one is the best, and it also has a great support team behind it. My experience with their support has been positive, as their guides regarding the integration are very useful. They have some awesome guides online that show you exactly how to configure the product, how to do the initial setup, and you can speak with them directly. They will be able to connect and verify your setup, run its parameters and see exactly what's working and what is not, and they really help you with that. StarWind Virtual SAN has positively impacted my organization and my customer through initial cost saving. They use this product in a dark site, so I'm not able to provide any additional details about this, but they were really glad about it, they're still using it, and they asked for extending the capacity for it and the support. They really want to use it and are enjoying using it.
