Hi,
First of all congratulate you on the forum and sorry for the English but thanks to google.
Well my problem is this .. I'm testing with open-and y xenserver but I did not get the performance you expect, because the I / O disk is very low and not what I expected.
He indicated the I / O disk of a VM with CentOS 5.8
[root@stor ~]# dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync
16384+0 records in
16384+0 records out
1073741824 bytes (1.1 GB) copied, 118.238 seconds, 9.1 MB/s
I have it configured the storage as follows:
Xenserver 2 nic:
1 nic: ip public
2 nic: ip private example 192.168.xxx
Storage 2 nic:
Bond: ip private example 192.168.xx
xenserver is connected via the private IP to the storage via a dedicated 1Gbps switch
the features of my raid are:
Hardware RAID info
Attribute name Value
State: Optimal
Strip size: 64kB
Raid Level: RAID5
Number of disk in one array: 7
Size: 5720064MB
Default Write Policy: Write Back
Read Policy: Readahead
Access Policy: Read-Write
Cache Policy: Cached
Disk cache: Disk's Default
Grateful if you could help me.
