10GB Network increased data bandwidth and IOPS

Up to 120k IOPS with our upgraded 10GB storage network

We began 2015 by upgrading our Cloud network. All our storage network, cards and servers were upgraded to utilise 10GB Fiber Optics connectivity. This upgrade improved storage backend performance tremendously, allowing RedyHost Cloud to eliminate bottlenecks and run more sophisticated and more frequent backups for our customer data. The 10GB network cards we use, provide traffic hardware offloading and optimisation, which results in faster transfers and better storage IOPS, that goes beyond simple bandwidth increase. In images above we include the result of our benchmarking test of the NAS environment, attached via the new 10GB link, comparing it to 1GB link […]

The problem we encountered was that installation hang on “Updating Boot Archive” message. It was quite surprising that we were unable to find a workable solution, while this issue was extremely easy to resolve. The Dell PowerVault x300 server we used (this step will be very similar to any Dell PowerVault or PowerEdge server) by default emulates USB drives […]
