Slow.......

[westm003]

Hello,

We have a Xenserver 6.2 with all patches setup with redundant switches and active/active open-e and 4x1Gbit Multipath setup.

Xenserver 4x1GB > 2 switches 2x2 paths > open-e node 4 x1Gbit cards)

We have in multipath.conf:

device {
vendor "SCST_FIO|SCST_BIO"
product "*"
path_selector "round-robin 0"
path_grouping_policy multibus
rr_min_io 100
}

We see in statistics of the two open-e nodes between 100-180Mbit traffic per network card and we have 4 in them... We also experience some slow performance during backup times...

Shouldn't the Open-e server in there statistics show 4 cards with 800-900Mbits of trafic? It feels that the Xenservers 6.2 are using 1GBit over 4 links? (4 cards on open-e times 200Mbit max = 800Mbit.)

Can some one please enlighten us?

as addition we never saw more then 100MB/s disk speed with dd test uncached
