MicroSD card RAID 1 as VMware ESXi boot device
MicroSD card RAID 1 as VMware ESXi boot device
If you install ESXi on a microSD card and if you use HP Proliant Servers you may be interested in the “HP Dual 8GB MicroSD Enterprise Midline USB” (HP P/N: 741281-002).
This dual-microSD card module provides data redundancy through a mirrored RAID 1 configuration. You connect the module to the internal USB port and install ESXi as usual!
If one of the SD card fails, the configuration of your ESXi host is still available and functional on the second SD card. In this case just replace the module with a new one, install the surviving SD card and configure it as primary.
The module has three status-LEDs:
- LED 1 – Power LED
Green: device is on and at least one microSD card is functioning
Red: both microSD cards have failed
- LED 2 – SD Card 2
LED on: microSD card has failed
LED off: microSD card is healthy
- LED 3 – SD Card 1
LED on: microSD card has failed
LED off: microSD card is healthy
