Can you connect the disk on storage system directly? btw, which link is 1 gbit and which is 4 gbit? NFS is connected with 1gbit and you want squid to be able to saturate 4gbit connection? -- Matus UHLAR - fantomas, uhlar@xxxxxxxxxxx ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
