hello
based on recomendation here from tom i have finaly bought and recived 5 adaptec 5805 card along with batterys inculded
i have installed one of them on the server
and here is the pveperf

vps:~# pveperf
CPU BOGOMIPS: 89604.31
REGEX/SECOND: 740463
HD SIZE: 94.49 GB (/dev/pve/root)
BUFFERED READS: 170.67 MB/sec
AVERAGE SEEK TIME: 10.19 ms
FSYNCS/SECOND: 3214.83
DNS EXT: 4018.13 ms


this on 2 x 1.5 TB disks configured as raid 1

i have tried to install adaptec asm but failed to start it
due x11 error

/usr/StorMan/StorMan.sh
Exception in thread "main" java.lang.ExceptionInInitializerError
Caused by: java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.

any recommendation to tune file system more?
as this a fresh server and am wating for an answer to migrate one of largest kvm vps windows to it

regards

I just copied the ASM files to Proxmox VE and as I do not have X11 on Proxmox VE I just run the ASM from my Linux Desktop.

Just connect via ssh:
Code: 
ssh -l root -Y IP_of_ProxmoxVE

now you can start the ASM (usr/StorMan/StorMan.sh) and the GUI is displayed on your Desktop.


  • Make sure the cache on the hard disks is disabled
  • Controller cache enabled, batteries backup
  • Optional: configure hotspare
 
thanks for your replay guys
i have installed and started x11 by startx
tried to login by xbrowser for my vista client but nothing
i dont have at the moment any gui linux box all kinda ssh access
any help would be really appreciated
 
you can also start the storagent on Proxmox VE and connect via ASM (GUI) installed on your Desktop.
 
fantastic work tom thanks so much i appreciate you spent the time to guid me through it

one last question as iam still new in adaptec
i enabled write cache enabled when battery

how do i make sure the cache on the hard disks is disabled

and any recomendation in read cache

regards

yes, this is the cache on the controller.

Click to expand...

click on each hard disk and select 'Change write-cache mode to write-through'

this menu changes and if you change it back to 'write-back' you will get a warning that this could lead to data loss in case of power failure. the cache from the hard drives are never backup up from a batterie so you always need to disable it. But if you have no raid controller cache you will get bad performance - but as you followed your recommendations you have a fast system now.

yes, performance will not go up if you disable cache but this is the most reliable way.

concerning pveperf: this is only a very basic benchmark and the results can change, never run if the server is under load.

additional, if you want a fast server you should not use cheap sata drives - go for SAS or even better, SSD´s (ok, too expensive in the moment).

To summarize, your setup now looks reliable now - if you want to improve performance in a notable way you need faster drives.
