I was going to finish this with the continued migration but thought we should talk about some of the system requirements for the SBS 2008 Server before we continue. On the SBS 2008 Servers I am specing we start with 8 Gig of RAM as the base and then adding memory from there depending upon the amount of users and what the server will be doing. I am also going with dual Quad Core CPU’s as these are getting cheaper. I am also doing a RAID 6 for the Server OS and DATA and apps and doing 2 drives in a mirrored set for use as the destination drive for the Exchange 2007 Continuous Replication which is basically a copy of the Databases and the logs files for disaster recovery which I will cover more on this at a later time.
We sell HP Proliant Servers and mainly the ML 350 G5’s at the moment so you have the ability of having 6 Drives for OS and DATA and the 2 for the Exchange Replication set. I know there is thoughts out there to do a mirrored set of 2 Drives for OS and then doing more drives for your data RAID 5/6 . I am still not sold on that train of thought as I have had WAY too many mirrored drives sets die where it takes the whole server down. You must remember these as small businesses that don’t necessarily check there server everyday or even at all and might not notice one of the Mirrored drives go bad and then have the remaining one go bad on you. That does not leave you in a good position so if you are running OS and Data on one RAID 6 drive set to me you are in a better position for that not happening.
Like I have said this is just my opinion and what I am going with and everyone will have their own opinions on what to spec or not to or how much and why. I am just going with what works for me and works well for me and my customers. Part 3 will be coming soon and we will finish the migration.
Till Later just Roger
