ESXi notes

i want to report my personal experience.

I installed custom HP version of esx 6.0U2 on a USB key, the datastore is a single SSD raid 0. I got very bad performance as reported by many users. Then i downgraded the driver to the 088version, but i got a lot of random problem (lost connectivity to volume).

So i decided to try the standard esxi 6.0U2. I got no problem, performance seems good (next days i'll post some tests) and no error reported

This is the result i got from CristalDiskMark, running on a Windows 7 64bit VM with 1cpu and 1GB of RAM. What do you think about? Should be interesting see other member performance :)

Just thought I'd share the ESXi 6.5 installation process I used, most of the info was obtained in this forum - thanks for all the great info

 

1. Download HPE custom vSphere 6.5 Nov 2016 iso 
 
2. Installed a 16GB SanDisk Ultra Micro SD and 4 x 2TB WD Red drives in Micoserver
 
3. Created a B120i raid 1 + 0 array 
 
4. installed Custom HPE 6.5 ESXi  on 16GB SanDisk Ultra Micro SD - eg via iLO remote console and mounting custom HPE ESXi iso as virtual drive 
 
5. log into ESXi via Web URL and created a new datastore - eg datastore1 
 
5. Enabled TSM-SSH (SSH) via web URL and SSH'ed into ESXi  (using PuTTY: a free SSH and Telnet client)
 
6. Confirmed read/writes are still an issue - Tested time to write a file to disk with the bundled scsi-hpvsa_5.5.0.102-1OEM.550.0.0.1331820 driver
# cd /vmfs/volumes/datastore1 
# time dd if=/dev/zero of=tempfile bs=8k count=1000000
 
1000000+0 records in
1000000+0 records out
real    8m 47.34s
user    0m 3.81s
 
no good, decided to downgrade
 
7. downloaded the hpvsa-5.5.0-88.zip archive (as per HP advisory) and uploaded the vib to the datastore. eg  /datastore1/patch/scsi-hpvsa-5.5.0-88OEM.550.0.0.1331820.x86_64.vib via the ESXi web interface
 
8. remove the exsisting scsi-hpvsa_5.5.0.102-1O driver (via SSH) (enable maintenance mode first)
# esxcli software vib remove -n HPE:scsi-hpvsa
 
Removal Result
   Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective.
   Reboot Required: true
   VIBs Installed:
   VIBs Removed: HPE_bootbank_scsi-hpvsa_5.5.0.102-1OEM.550.0.0.1331820
   VIBs Skipped:
 
9. Install the scsi-hpvsa-5.5.0-88 downgraded driver 
# esxcli software vib install --viburl=/vmfs/volumes/datastore1/patch/scsi-hpvsa-5.5.0-88OEM.550.0.0.1331820.x86_64.vib
 
Installation Result
   Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective.
   Reboot Required: true
   VIBs Installed: Hewlett-Packard_bootbank_scsi-hpvsa_5.5.0-88OEM.550.0.0.1331820
   VIBs Removed:
   VIBs Skipped:
 
10. Disable ESXi vmc_ahci module (if not completed, ahci is used by default. eg array is not initialised via hpvsa and ahci initialises disks as 4 separate physical disks) 
# esxcli system module set --enabled=false --module=vmw_ahci
 
11. Reboot Server
 
12. Re-test file write speed to local data store (disable maintenance mode and enable TSM-SSH first)
 
# cd /vmfs/volumes/datastore1 
# time dd if=/dev/zero of=tempfile bs=8k count=1000000
 
1000000+0 records in
1000000+0 records out
real    1m 40.79s
user    0m 3.70s
sys     0m 0.00s
 
much better

does anybody updated allready this?

Do I have to install esxi 6.5 with scsi-hpvsa-5.5.0-88 again?

 If using the onboard B120i then yes I recommend downgrade to resolve driver read/write performance issue, see my post

Have just downgraded the drivers (at least I think!) - Any way I can check?

Still quite slow compared to your results...

Even worse on my VM Datastore; - I admit this is just a 2.5" temp drive until I get around to sticking in an SSD.
