Hi,
small business <10 people with a small server running 2012 R2 doing DC, file serving and hyper-V with 2 guest VMs, 1 running a small db app on one of the guest VMs (quickbooks enterprise DB) and the other running an old internal single-user progam we
need for (!)
as the root is acting as a file server (although this is easy enough to change but I dont want too many VMs as its not exactly a monster of a server or anything), the guest VM needs to access a largeish shared file which is currently stored on the root and is accessed via a share.
This file is currently 450MB and is the quickbooks company file (no, it wont shrink any more).
Whats the best way to setup this file ?
1) as it is on a share on the root, that the guest VM accesses as a share using the virtual adaptor
2) inside the guest VM vhdx ?? (a bit scary).
Will #2 faster or slower (assuming it were all to end up in the same RAID array as it it were on the root but now inside a vhdx) than accessing via virtual switch to a share on the root (same physical raid array but over the virtual switch layer as opposed
to the vhdx layer)
if #1 is faster, I assume I get better performance if the guest VM access the shared file from the HOST via an internal virtual switch vs dedicating a GB NIC (via a virtual switch that does not include the host NIC) to the qb guest VM and having it communicate via actual wires to the host (surely the internal virtual switch has to be faster)
what if guest vm and host share an external virtual switch, is there any performance difference in terms of guest accessing host if the host is also using external switch for other network jobs ?
should I setup a) internal virtual switch for just guest -> host operations and then b) use "dedicated" NIC for guest -> external and another for host->external ?
is there another, better way ? i.e. qb server on the root, not in a vm, accessing local file on the root
