I have a Oracle Enterprise Linux box, the kernel is 2.6.18...,
accessing LUs in a NetApp Box.
At NetApp box side, I have two Gigabit Ethernet NICs, each NIC is
member of a VLAN and this two interfaces are members of a
At Host side, I have two Gigabit Ethernet NICs, each NIC is member of a VLAN.
I have this configuration at DM-MP conf file:
When I simulate write operations on a LU I reach 90MB/s on each NIC.
When I simulate read operations on a LU I reach 40MB/s on each NIC.
It's a very poor number.
When it is running on Read Operations I can see the devices /dev/sdb
and /dev/sdc at 50% busy each and the dm-1 at 100%.
Anyone can help me to identify Why this throughput to read is poor?
NetApp - Enjoy it!
