I've installed Unity 5 with active and standby configuration, it's been in production for a year and a half and doing well. I have had some trouble in the past as it relates to how the platform configuration disc allocates space to the C drive, however. On both servers, 12gb is allocated to C:. Only the OS is stored there, absolutely everything else is put on the second partition. In our setup, I find that the C: drive's default setup isn't as suffcient as Cisco planned it to be as OS updates and log files slowly eat away at the free space on the drive. Over time, I've been finding the space to be slowly decreasing (this is a very gradual process.) At one point, a bug in the Win2K3 appliance software wouldn't allow the OS to delete log files and I almost ran out of space on C: completely (luckily, I caught this in time and resolved.)
My question is; has partition size been increased on C: for the platform configuration disc in the following version of Unity? I find it ironic that the drive that needs the most space (C:) gets the least. The second drive is 136gb and I'm barely using 1gb of it.
Also, I know what the drives are for, don't explain about the MTU, the storage of messages in an outage, etc. I know this. Just want to know if C: drive is more spacious in version 7.
