ODD in Gen8

Recommended Posts

RichE

Hi all, long time lurker, first time poster.

 

I have a Gen8 Microserver which I am setting up for use as a small homelab. I have an ODD plugged into sata port 5 with the four drive bays going into a P222. The intention is to run ESXI from the internal usb and have some VM's to tinker in Windows, Linux and pfsense (ay least initially). What I need some advice on but have been unable to ascertain from searching the net is whether I should enable the b120i or ahci? If it is the b120i then do I need to set the ODD as a single raid0?

 

Thanks in advance.

You might find this useful https://www.admfactory.com/hp-microserver-gen8-boot-from-ssd-install-on-odd-bay/

 

I used to have this setup on my freeNAS Gen8 but I would often find that I had to reset it back up when the boot sector on the SSD was updated. You won't have this issue but the final straw was later versions of grub not recognising the drive. In the end, I ditched using port 5 and bought a USB to SATA cable and used the internal USB connector. Been fine since.

 

Why boot ESXi from the SSD? It is easier and recommended to boot ESXi from a USB stick. That is what I do for my ESXi Gen8. Then you potentially free up the SSD drive for fast storage as a datastore.

Misread your OP. You *are* booting from the internal USB not SSD. Article should help.

Thanks for taking the time to reply Paul, unfortunately I don't think I explained my question properly. I will be running an actual DVDRW on port 5, not an SSD in the ODD space.

Looking at adding a BDRW myself, I am using the internal SATA for my boot SSD so I was considering a USB to SATA:

Anyone else used one of these onto the internal USB?

Yes, I tested several models, they're working fine. Also, they're 2$ on AliExpress.

Thanks Korby, I actually have 3x USB external BDRW's that I got free as they have issues.  2 of them are ASUS SBW-06D2X-U and in a YouTube video one is torn apart to reveal the board shown below (which appears to be slim SATA to USB2).  The only issue I see is that ASUS supply a double USB A to mini B cable - which I don't have and perhaps is the reason why some of these drives are not working anyway:

So I bought an LG BU20N internal SATA drive, now awaiting that Slimline USB adapter.

 

In the meantime I did some testing with my USB BDRW drives (ASUS SBW-06D2X-U & SBC-04D1S-U), I got these free as the seller stated they didn't work fully.  After some testing, they work fine with my Dell XPS 15 laptop and NUCi5, they don't however even show (despite the USB sound) when plugged into Gen8 USB2 or USB3.  I am using a single USB to USB cable, so no extra power from a 2nd port, could that be the issue?  Unfortunately I don't have such a cable to test my theory
