<DIV><FONT size=2 face=Arial>Hello <FONT size=3
face="Times New Roman">Michael</FONT></FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>I once took a course about Windows 2008 servers
(but I am not an expert, I didn't even install it).</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I will try to point some subjects:</FONT></DIV>
<DIV><FONT size=2 face=Arial>MS has hyper-V which is their virtual
platform.</FONT></DIV>
<DIV><FONT size=2 face=Arial>They have a tool that convert a physical server to
virtual server (I think it is called VSMT).</FONT></DIV>
<DIV><FONT size=2 face=Arial>I think they have a tool for load balance in a
virtual cluster NLB, and a tool for cluster fail over.</FONT></DIV>
<DIV><FONT size=2 face=Arial>MS also have a server version without GUI, to
reduce resources requirement and enhance security.</FONT></DIV>
<DIV><FONT size=2 face=Arial>They admit that VMware is better, but they claim
that they provide a complete working solution.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>If I had to build the system I would:</FONT></DIV>
<DIV><FONT size=2 face=Arial>1. Measure the load of all the servers (this will
give a clue how many physical servers I really need).</FONT></DIV>
<DIV><FONT size=2 face=Arial>2. Put all the data on external file system (this
is a must if you want to move a virtual server from one physical machine to
another).</FONT></DIV>
<DIV><FONT size=2 face=Arial>3. Create a virtual cluster with fail over. The
resources of the cluster should be enough that in the case of failure in one
physical server, the rest of the cluster will hold all the virtual
machines.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Sorry that I can't come with real
suggestions.</FONT></DIV>

<DIV dir=ltr>Hi there,<BR><BR>I'd like to ask your oppinion on the
virtualization of several WINDOWS servers installed on a client's medium
business server room. There are about 6 crucial servers (priority, exchange,
file server, and some others) that need to be accessible when they fail.
Currently, each server has its own RAID storage. There is only 300GB of data
to be kept on those servers (mostly exchange and file server). The virtualized
servers should become alive when one of those main servers dies, and
theoretically, no more than 2 VMs should be running in parallel.<BR><BR>What
would be the best virtualization platform for such a requirement ? Windows
2008 server, or XEN ? <BR>Would a fast single Xeon processor be able to handle
this requirements ? 8GB or 4GB ?<BR>Would you consider VMWARE on top of CENTOS
?<BR>Would you suggest that the data should already be kept on a NAS appliance
as of now, even before DRP takes place ?<BR>(If yes), which NAS solution would
you use ?<BR>Would you consider a cloud-based backup program such as Crashplan
to backup this data ? Is there any other enterprise-level backup app that can
store backups on cloud storage ?<BR><BR>I appreciate all your answers
!<BR><BR>Michael
