Hey Nick,
We run Fedora DS inside Virtuozzo VEs (not VMWare) and don't have any capacity
concerns, our environment sounds like a good tenth the size of yours though. Each VE
(there's 2) has only half a GB of RAM and does about 100 connections a minute, however
our LDAP database is very small, so the memory we've allocated is massive overkill. In
terms of CPU usage, the VE does practically nothing.
I wouldn't think you'd need much more RAM over the size of your LDAP database
files, so unless you've got 8GB of LDAP information, 8GB of RAM sounds a lot to me.
Our LDAP database is only about 40MB, which is close to the RAM usage of the VE.
Our stats, might help you decide on what you need. Maybe someone more knowledgeable in
the DS internals could explain the large virtual table size.

Subject: [389-users] Fedora DS with virtual machines
Hi All
Does anyone have any experience running DS in a virtual machine? Our
current LDAP infrastructure is quite busy, 500-1000 connections/
minute, with >6.5 million operations per day. The VMs will have up to
8GB of RAM, though we think we'll only need 6.
We're performing testing with slamd, but it's hard to get truly
representative stress testing using this tool I think.
What has your experience been like? Any snafus to watch out for?
Thanks,
Nick
