We are planning on doing virtualization of apps in the coming years..
We are a small size company with about 40 users .. 2003 architecture..
about 5 servers, with two of them DC's..
Exchange02 server: 6gb memory.. Xeon Dual Core woodcrest 2.0ghz, dual
CPU, mirror OS, mirror log stripe, raid5 data array, 2003 x64 server
(on average, 7gb of 6gb in use, days after a reboot, though initially
only about 3200mb in use on bootup), DUAL gigabit nics
ServerB: Xeon 2.4 GHZ CPU (non x64 capable), 2gb memory, mirror OS,
raid5 data stripe, Sourcesafe, sql server 2000 (3 instances) , sql
server 2005 (1 instance), WSUS 3.0, sharepoint server 2007.. 2003 x86
server; (memory used at fresh bootup about 1500mb, days later..
2100mb); single gigabit nic; This server will probably get upgraded
to a new one in the next 6 months, with more space / memory etc.
Backup01: xeon woodcrest 2.0ghz, dual core, dual cpu, 4gb memory,
2003 x64 server R2; System Center DPM 2007 or Symantec Backupexec
(still deciding).. Primarily for backups to hardisk over the network
to this machine, then from this harddisk to the tape drive array
dlts4.. dual gigabit nic; 1.7TB array for backing up 730 GB of data
from other servers. Mirrored OS, raid5 1.7TB array.
ServerDC: xeon DP (x64 capable), 3.0ghz, 2gb memory (1700mb used on
average); 2003 x86 server; SQL 2000 (2 instances), Dynamics 9.0,
file server, SMS 2003 (probably will upgrade to system center manager
2007), FP, DHCP, DC, TrendMicro antivirus server, UPS shipping
software, DNS; single gigabit nic; Mirrored OS, RAID5 array, cant
expand any further, space limitted here.
BackupDC: P3 800mhz, 1gb memory, DHCP, DNS
ServerC: Pentium D 2.8ghz, 2gb memory; SourceSafe DB here too;
mirrored OS, raid5 array (500gb), space limitted here, but can
dynamically expand this array for more space. System Center
Operations Manager 2007; (used memory at least 1800 MB of 2000)
Of these servers.. which are the best candidates for virtualization?
In their existing state, i'm assuming I would just install virtual
server.. but I would also be able to use Operations manager to
determine the best Host.. and Virtualization Manager for management?
I'm guessing that Backup01 and Maybe ServerC would be ok candidates,
especially if i increase the memory?
I was considering running Exchange 2007/ OCS 2007 Edge server in a
virtual machine on one of these, maybe backup01.. Then again, I dont
want to bog down our backup server, but it also only backs up at
night, so this may not matter... I'm guessing i could throw a public
ip on the secondary NIC on one of these servers, then the edge virtual
server would be set... (also not sure if the edge OCS server, to use
live meeting with non domain offsite people would require ISA 2006 or
similar, as i've never used that product thus far)..
I was also considering virtualizing some of the products already on
some of the other machines to consolidate resources and apps.. I'm not
sure of these apps, which would be the best candidates for this?
I'm also not sure on the memory settings for the virtual servers i
would make.. usually, i think virtual server would set something like
512kb of memory to a virtual 2003 server.. but with the kindof apps i
want to run, would i really want to set it to the more "real" value of
2gb (and add more memory to the host)?
Finally.. I noticed that virtualization wont be available in 2008
server till maybe next september.. Will 2008 server be able to
just run virtual server in the meantime on these boxes.. then
year?
Thanks in advance.. |
