Subject: Re: [plug] Virtualization (was Re: On Dedicated and Virtual
Hosting)
4. I/O is the number one problem for VMs: if you have a high I/O
applications such as file or database server, VMs will give much lower
performance compared to dedicated servers.
I guess it's better to run the db engine on the physical server, then
access it over the virtual network?
That is much better, put DB on seperate servers and run app servers, say
websphere, in VM.
any resources (eg. cpu, network i/o, ram, etc) that are being shared by VMs
will not perform well versus to standalone machine (of course)...
BTW has anyone here has used JFS for database? Thus it has support for
concurrent i/o?
enhanced jfs also known as JFS2 has a new filesystem feature called
concurrent i/o (CIO)...
fooler.
