Сервер ESXI выключает жесткие диски, когда никакая активность диска не обнаруживается?
Я был в магазинах, которые используют Digicert для этой очень точной вещи. Проверьте их WildCard плюс сертификаты.
No, it does not. In most environments this also would not make any sense since
- there hardly ever is idle time for a hard disk hosting a data store for a number of virtual machines
- no RAID controller would support spinning down individual disks and running ESXi without a RAID controller with BBWC would result poor I/O performance for the guests
- spinning hard disks down and up is regarded as "not a thing to do" with server hard disk drives as a disk has a limited number of "load/unload cycles" which it is able to take and also might fail on a spinup due to the increased electrical and mechanical load at this time
If you need spindowns, your only option would be to separate the disk(s) out to a different enclosure where you have the appropriate level of control (e.g. to a Linux- or BSD-based iSCSI target) and reference it from either ESXi to create a data store or directly from within your guest.
That would be a function of the server hardware, disks and array controller you're using.
By default, no, ESXi wouldn't do this, because that's an undesirable feature. Most server-class hardware wouldn't be set to spin down drives either by default.
Edit:
Something like an external USB drive, however, may spin-down. But that's a unique case.
