VMware vCenter Server 5.0 & MS SQL Server ODBC

In my vSphere lab environment I like to try and run things as closely as possible to how it would be run in the “real world”.  Of course this isn’t always possible due to hardware and budget limitations although there are a few things I can do such as running a dedicated database (DB) server VM(s) from which to run the different vSphere related DB instances, such as vCenter, Update Manager, View, etc.  This is as opposed to running a locally installed SQL Server Express instance for every … [Read more...]

Running VMware vSphere 4.1 on a MacBook Pro with dual disks (incl SSD)

I’ve been using my Intel i7  MacBook Pro daily for work and then during the evening for the past couple of months and have found it, on the whole, pretty good.  I bought my MacBook Pro with a 5400rpm SATA based internal disk as to buy a MacBook Pro with a 7200rpm SATA or SSD drive a special order was required which would have taken a number of days to come through which at the time I didn’t have the luxury of.  Disappointingly my MacBook Pro hasn’t been quite as responsive as I’d … [Read more...]
