I have a performance issue with my SAN. I have a full 10Gbps private network setup. I have the following setup
1 - Mac with Connected with via Fiber Transciever 10GbE
1 - Windows 7 PC with 10GbE
1 - HP Switch with All ports are 10GbE
2 - Quantum StorNext Servers with 10GbE
1 - Dell Compellent Solution with 2 Controllers connected to the network at 10GbE
All servers, switches, and computers have staticly assigned IPs
Compellent Config
Tier 1 - 10K SAS Drives in RAID 10
Tier 2 - 7200 SAS Drives in RAID6 (12 groups of 13 Drives in Each)
Additional info
Windows 7 Client TCP Offload Options
IPv4 Checksum Offload - Enabled
TCP Checksum Offload - Enabled
UDP Checksum Offload - Enabled
Large Send Offload - Enable
Jumbo Packet - 9014Bytes Enabled
I mounted the StorNext volume on my Windows 7 PC and my Lion Workstation. Unfortunately all my transfer speeds are at around 2Gbps or 2.8Gbps (if I'm really lucky). I was looking to get at least 5Gbps speeds out of this setup, but I'm averaging about 2Gbps or a little above 250MBps transfer rates on file copying. When I map a LUN directly to the boxes and then format it natively with either HFS (with journaling) on the MAC or NTFS on the Windows 7 PC, and then copy a file, I get about 180MBps. So my performance on a directly mapped LUN is slower than my StorNext Volume. Any suggestions? Has anyone seen degraded performance on iSCSI with 10GbE? Any help would be Awesome! Thanks!
