Hello to you all, that’s my first message on this forum.
Hope to find solutions and contribute to community.
Here the matter of this message.
i have the following WD Hard disks:
-WD5000AAKS
-WD5000AAKX
-WD20EARX
All them for setting up a file server:
OS - ubuntu server 12.04
Controller - Highpoint 2720SGL (now connecting my hard disks) and 2680SGL - all fine installed in OS.
Mobo - Supermicro PDSME+
My intention is to setup a software raid5, and with 8 devices it’s usefull a Staggered spinup/PM2 (supported by controllers in their bios) to reduce current absorption at system startup.
There is a pdf guide for jumper pins on WD disks:
http://www.wdc.com/wdproducts/library/other/2579-001037.pdf
but in a note it’s written: “Note: The PM2 feature is not available on all WD SATA drives”
ok, but which one ?
Where is a list of hard disks supporting the PM2 ? Are my models ?
My test impressions:
WD5000AAKS - support
WD5000AAKX - no
but not sure.
An official note/list would be appreciated.
Thank you for sharing your experiences/informations.
