memcached server hardware requirement?

[linuxman]

Hello Memcached guru,

We want to use memcached in our web site, and would you like to
recommend the server hardware requirement? I have read the mailing list
archive, but not found the answer.

I suppose such server configuration: 

motherboard:tyan S5350G2NR
cpu:xeon 5030(single kernel)
mem:8G
OS:linux(debian)

Is this configuration good enough? 

Thanks in advance!
