Публикую больше для себя, чтобы не забыть, но может быть окажется полезным и для кого-то ещё.
Сторадж NexentaStor 3.1.1, 8x2Tb HDD в RAIDZ2, 1x80Gb SSD под cache, Intel 82599 10Gbase-SR сетевая, отдаётся через iSCSI и через NFS.
Проблема - iSCSI что с MPIO 4x1Gb, что с 1х10Gb сетью не позволяет получить скорость более ~90Мбайт/сек.
В итоге после тестов остановился на использование NFS в качестве datastore для VmWare ESXi 4.1. Результаты теста скорости для виртуалки в ней приведены в самом низу.
