Not long ago, Schoondoggy asked a few of us to beta test preproduction versions of his drive mount bracket for the HP ProLiant Gen8 MicroServer. Except for the placement of the holes to attach the Schoondoggy Gen8 Drive Mount (“SGDM”) to the PSU – which was easily fixed with my Dremel – the SGDM is perfect in design simplicity coupled with high flexibility. With the SGDM I could mount two 2.5” drives (like VelociRaptors or the 2.5” WD Red’s), or 2.5” SSD’s, or a single thin 3.5” drive – all the while still leaving the ODD bay open for the Optical Disk Drive or one or two SSD’s! I can disconnect the drive cage SAS cable and attach a SFF-8087 to the system board giving me two SATA III ports (SATA cables 1 & 2 off the SFF-8087) and two SATA II ports (SATA cables 3 & 4 off the SFF-8087) all controlled by the HP Dynamic Smart Array B120i RAID Controller. The now free HP SAS cable to the drive cage could be attached to an add-in card (such as an HP P222) providing functionality for four 3.5” drives in the drive cage.
The HP ProLiant Gen8 MicroServer is a fun machine to work with -- but the SGDM takes it to a whole new level! Thanks Schoondoggy! In my opinion, if you have a Gen8 MicroServer -- you are going to want a Schoondoggy Gen8 Drive Mount.
In early August, 2013, Schoondoggy announced in the HSS Forums that he had a prototype of a drive mounting bracket to enable him to mount two additional 2.5” drives in the recently introduced HP ProLiant Gen8 MicroServer. Many on the Forums were encouraged by Schoondoggy’s efforts to refine his design and bring his bracket to production. His idea would enable the option of two drives within the Gen8 case in addition to the main 4 drive bay and the ODD.

At the Home Server Show Meetup 2013 Schoondoggy displayed his HP ProLiant Gen8 MicroServer prototype drive mounting bracket and I was amazed to see how he had fit the additional drives in the available space and came up with a cooling solution. This was one of the highlights of the Meetup for me and I took several pictures of Schoondoggy’s display which are included in the MeetUp 2013 Wrap Up Photos section.

Beta Test Preproduction Copy – Schoondoggy Gen8 Drive Mount
Recently, Schoondoggy sent me a Best Test Copy of what I’ve decided to call in this write-up the Schoondoggy Gen8 Drive Mount (“SGDM”). I will now address my unboxing, installation, and testing of the SGDM.
Figure 3 -- The SGDM Unboxed and displayed next to HP ProLiant Gen8 MicroServer
The SGDM unboxing is recorded in the following video:

Figure 5 -- SGDM Attached to Gen8 MicroServer without Drives
Figure 6 -- Location of Mounting Holes for 2.5" Drives/SSDs
Figure 7 -- Location of Mounting Holes for Thin 3.5" Drive
Figure 8 -- Additional Parts Needed: 8 Drive/SSD screws & 8 Neoprene washers
Additional Parts Needed:
- 8 -- 2.5” Drive/SSD Mounting Screws (if mounting a 3.5” drive only 2 screws are necessary)
- 8 – Insulated (Rubber or Neoprene) washers – I used 3/8” OD w 5/32” ID

Figure 10 -- Bit used to Counter Sink Drive Mount Holes -- work slowly and carefully and check often if hole is counter sunk enough
Mounting 2.5” VelociRaptors (without Ice-Pack) to the SGDM and attaching the SGDM to the MicroServer
Mounting Two 2.5” VelociRaptors is shown in the following video:
Figure 11 -- Note the Air Gap Created by using the Insulated Washers between the SGDM and the 2.5” drive (VelociRaptor in this case) -- Air Flow from the Blower in this Air Gap will help cool the VelociRaptor (Note that the screw holes to mount the drives to the SGDM have not been counter sunk yet in this photo)
Figure 12 -- 2.5" VelociRaptors attached to SGDM and screws have been counter sunk
Figure 13 -- The only Modification that was necessary on the SGDM was to use a Dremel to grind out the PSU Attachment holes towards the end of the tab to line up with the PSU mounting bracket holes -- future production units will have this corrected
Mounting 2.5” SSD’s to the SGDM
Mounting Two 2.5” SSD’s is shown in the following video:
Mounting 3.5” Thin Hard Drive to the SGDM
One 3.5” Thin Hard Drive can be mounted to the SGDM as shown in the following video:
Power & Data Connection for Schoondoggy Gen8 Drive Mount (“SGDM”)
- 1 Athena Power Cable-YPHD 8” Molex Y Splitted Power Cable
- 1 Nippon Labs SATA Adapter Molex 4-Pin PC Power Cable to 2 x SATA Converter Cables for SATA 1 and SATA II Hard Drive Model POW-SATA-2
- 1 4-Pin Molex to 4-Pin Molex & 2-wire Fan Power Adaptor (I have several of these that were included with my HAF & Lian-Li cases over the years – this is the first time I got to use one)
- 2 Male 22awg quick connector (over kill for this build but I had these in my parts box – I had gotten them at Menard’s some time ago – the best way would have been to attach a fan connector to the SGDM Blower and then just plug it in)
- 2 Female 22awg quick connector (over kill for this build but I had these in my parts box – I had gotten them at Menard’s some time ago – the best way would have been to attach a fan connector to the SGDM Blower and then just plug it in)
