Hy,
Does DSS V7 support VAAI for Vmware ESX 4.1 / 5 ?

I understand it's a problem with ARECA but definitly after this problem, i want that DSS stop all access of my volumes for iSCSI or NAS.

On my ARECA 1680 i have two volume : 10*400Go SAS RAID6 and 4*2To SATA RAID10.
I have some random error on my SATA Volume (never on my SAS volume or at...
After the restart of replication task, the lv0003 goes down and nothing working anymore.
I have to hard reset my two ESX Host after a proper restart for OpenE.
But the data stored n VMDK from...
Thanks for the info about MTU on Bond.
Hi To-M,
For MTU, i can't change it. When Bond is up, with the console management i can only change the MTU for Bond not the MTU for each attached NIC :
...
Thanks Tom, i have no error in Areca management.
i'm creating a support ticket right now.
Hi,
I have a strange and undocumented state for my replication :
Protocol type: Synchronous
Connection: Connected
Source info:
Logical volume: lv0003
Consistency: Diskless...
With ESX 4.0 / 4.1 you can use OpenE as guest.
But no vmware tools.
Hi,
For me, you can't aggregate bandwith with bonding.
You have to use MPIO.
thanks for the info, i'll try this.
what is the "goes down" parameters ?
i have 2 DSS V6 with replication WITHOUT Failover because i use round robin MPIO Vmware.
This saturday, my master DSS V6 "goes down" :
- scsi error command...
hi,
i found my old post, finally i found the trick in vmware thant i neved posted back here...
In fact, we just have to change the round robin policy (iops options). I assume that you have MPIO...
i dont find this kind of option in Vmware.
Following a blog message, i just have to activate Round Robin option.
I'll wait for V6 then...

on esxi host i add 10.0.0.3 for iscsi

ok red now i have understand :)
I want to have HA Open-e so i have only one Virtual IP for link between client & OpenE... I can't use Mpio on IP for the link... (Or may be DSS V6 can give me more...
I aggree with the fact that replication must not impact read performance.
My ESXi 4 is in MPIO support RR Vmware : i see activity on my two ETH for iISCSI traffic (but may it's not working...)
...
But CX4 is limited to 15m right ? Looks like it will be too short for me (my two san are not on the same floor).
On 10GBase-T it's 100m with copper but i can't find a switch 10GBase-T (8 ports?)...
what is your bond config in OpenE ?
I tried Balance RR, Balance-ALB & 802.3ad.
In Balance RR i get better write but lower Read...
May be Xen do better...
And with balance-rr and two crossover cable NIC-to-NIC can i expect to have better performance ?
Thanks a lot for this info :)
