Pinned topic V7000 bug - bad performance on Node2, port4 with iSCSI

‏2013-03-26T14:55:40Z |

We just implemented a V7000 with four X3550M4 with VMware 5.1. Each ESX server has two vmkernels for iSCSI and each datastore has 8 path. Performance is great on all path from the four servers except for Node2, port4. Benchmarking with IOmeter gives me 700MB/sec on all path except the two path Node2 port 4 (140MB/sec) There is nothing currently running on the SAN and ESX servers. V7000 is running latest firmware

Anyone seen this before?
