Would it make sense to virtualize windows using Xen or VMware ESX and expose storage on a JBOD as NFS, instead of exposing storage as CIFS/SMB for better I/O throughput?
Is it true that the below can yield only 20MB/sec for CIFS/SMB; 80MB/sec for NFS? assuming i use 2-3 servers (1Gbps NIC), NIC teaming, switch binding, jumbo frames etc...
My test rig can only afford:
- Storage server: HP DL370G6: 2x Xeon 55xx -CPU, 16GB RAM, 300GB 10K RPM SAS, P410i - 512MB cache
- Windows server: HP DL580: 2x Xeon 56xx, 64GB RAM, 1G NIC
- HP procurve 3500 layer3 switch - 1GB
Planning to use distributed file system: GlusterFS (user space) over Redhat ent Linux 5.5/ext3 FS, but I am attracted by a Solaris post about CIFS @ 1Gbytes/sec !
I am torn between the two... I know my hardware is not at par with above post, but does OpenSolaris offer better CIFS/SMB perf than any other?
Thanks in advance for your thoughts!
