Best uses for servers that have been replaced with a hyper-converged environment

If you haven’t already implemented a hyperconverged infrastructure, you are at least thinking about trying it out. After making the switch, you will have an existing infrastructure that probably consisted of a traditional 3-2-1 or “inverted pyramid” architecture that will be replaced with your shiny, new HC infrastructure!

Dell PowerEdge FX

Deployment Scenarios for the Dell PowerEdge FX

The Dell PowerEdge FX enclosure might, at first, be a bit of a mystery. For all intents and purposes, this is a 2U rack mount blade chassis and, in many ways, it is the baby sibling of the 5U VRTX enclosure.

Booting Dell PowerEdge from SD Card

Booting Dell PowerEdge from SD Card

Many Dell PowerEdge servers have an option to boot select hypervisors from either a single SD card or dual mirrored SD cards. The advantage of this is that the server can be diskless or the local storage is not consumed by the hypervisor. The primary drawback is that SD cards are not meant for continuous writes so only hypervisors that do not routinely write to the OS partition are supported. A second drawback is that reads and writes are slow so it works best for OS’s that are fully load into memory during the boot process.
