I have a lab-environment with ESXi 5.1-servers, they are installed on USB-drives.
There is a production environment I work with, which has ESX 4.1 servers, these are installed to SSD-drives. However, for config, choice has been made to move ONLY the scratch-partition to a SAN-drive.
Reason = SSD’s would be worn-out due to frequent read-writes.
*is the reason above a valid reason/reason to move the scratch-partition, also for (my) ESXi 5?
I always understood, you could remove the USB-drive once server has been booted, since everything runs in RAM (never tried it though)?
*if moving scratch-partion is advisable, is there an article + is there performance gain?
