hyper-v snapshot sizing

-

im configuring hyper-v server host 5 virtual machines.total capacity 100tb.if want run snapshots how calculate capacity snapshots

unless understand how goiing implement snapshots, difficult anticipate.

there 2 types: when vm running, when vm powered off.

when vm powered off need worry virutal disk snapshot files.  when vm running need worry virtual disk snpashot files in addition saved runngin memory state.  configuration , meta data small barely worth worrying about.

the saved memory state easier deal equal the memory setting of the vm.  2gb of ram = 2gb saved state file.

the virtual disk snapshots files are different story.  each differencing disk, means each has maximum size equal first vhd in chain.  amount of change that is written disk between each snapshot determins how large each be.  conservative estimate each snapshot can equal parent vhd size.  so, if have vm 40gb virtual disk snapshot take additional 40gb of storage (unlikely, happen).

oclist /xml or /?

oclist have qualifiers? can behaviour changed, example output xml?   given previous comments andrew m , comments in forums , blogs think answer no, it’s simple app calling underlying api, thought i'd ask can't seem find anything.   why asking question? i'd @ least 2 things oclist (apart nicer looking output [which i'm not going get], dependances listed [dicussed in forum , ruled out], , refrushing add ad componets , telling use dcpromo [which in banner know]): - whether installing component cuase / require reboot (currently believe qwave , printing services require reboot)   - xml output, can't justify team looking see if can commality with full server   fwiw :j   hi,   oclist not have qualifiers or ways change output. when iis came in late, make oclist output longer, unfortunately late make significant changes.   i'll take feedback , add our list next version.   thanks,   andrew   ...
