Adding more disks to an Ultra 10
From default, the Ultra 10 can support 2 x IDE hard disks.
You have 1 hard disk on a bay just under the power supply and the second hard disk that sits in the 5 1/4 bay underneath the CD-ROM.
You can in fact with the right cable and screws fit a third hard disk inside the chassis just above the floppy drive.
However if using this media bay, your hard disks would have to be low profile disks to achieve this such as the Seagate single platter LP 500GB.
Attaching these drives together is simple using 2 x IDE cables however you will need to modify OBP's boot aliases to cope with the new drive device paths.
For example, if you add a second drive, the CD-ROM will need to move up to being a slave device. This means it will become target 3 not target 2.
So, your OBP device alias for "cdrom" will need to change from the master position target 2 to the slave position target 3.
Your new hard disk will become the master on the second IDE channel meaning it becomes target 2.
Adding a third disk will require you using the third disk as a slave on the first IDE channel with your root disk. This will become target 1.
The Ultra 10 will then look like this:
root disk, master, first IDE channel, target 0
new disk, slave, first IDE channel, target 1
new disk, master, second IDE channel, target 2
CD-ROM/DVD, slave, second IDE channel, target 3
What I did was use a compact flash as my third disk and put the Solaris operating system on the compact flash. I then played with mirroring and ZFS using the 2 remaining 160GB HDD's I had installed.
I placed the compact flash (8GB) just above the floppy in the media drive bay using a disk bracket. Connected it as master to the first IDE channel.
Then I made the 2 x 160GB HDD's as the slave of the first IDE channel then the master of the second IDE channel. This worked really well and made my Ultra 10 seem like a modern SSD platform.
You probably should not do this though as you will need to practise root mirroring with your exam not just data disk mirroring.
So, try to obtain 2 of the smallest IDE hard disks you can get. 120GB's would be perfect but 160GB's waste a little space as the Ultra 10 will only see 128GB for it's root / boot disk.
Setting up of a root mirror via SVM or ZFS is well documented on Google. It's just a few small commands.
Hope this helps,

Oh, and don't worry about power / cooling.
The old 9GB and 18GB IDE drives that the Ultra 10 came with used far more power than a modern drive and thus generated far more heat. This disks sometimes used up to 15 watts.
Modern disks will use a fraction of that like 2 - 7 watts depending on disk and size.
The Ultra 10 will feel like it's been given a vacation.

HD(4) Linux Programmer's Manual HD(4)
NAME
hd - MFM/IDE hard disk devices
DESCRIPTION
The hd* devices are block devices to access MFM/IDE hard disk drives in raw mode. The master drive on the primary IDE controller (major
device number 3) is hda; the slave drive is hdb. The master drive of the second controller (major device number 22) is hdc and the slave
hdd.
General IDE block device names have the form hdX, or hdXP, where X is a letter denoting the physical drive, and P is a number denoting the
partition on that physical drive. The first form, hdX, is used to address the whole drive. Partition numbers are assigned in the order
the partitions are discovered, and only non-empty, non-extended partitions get a number. However, partition numbers 1-4 are given to the
four partitions described in the MBR (the `primary' partitions), regardless of whether they are unused or extended. Thus, the first logi-
cal partition will be hdX5. Both DOS-type partitioning and BSD-disklabel partitioning are supported. You can have at most 63 partitions
on an IDE disk.
For example, /dev/hda refers to all of the first IDE drive in the system; and /dev/hdb3 refers to the third DOS `primary' partition on the
second one.
They are typically created by:
mknod -m 660 /dev/hda b 3 0
mknod -m 660 /dev/hda1 b 3 1
mknod -m 660 /dev/hda2 b 3 2
...
mknod -m 660 /dev/hda8 b 3 8
mknod -m 660 /dev/hdb b 3 64
mknod -m 660 /dev/hdb1 b 3 65
mknod -m 660 /dev/hdb2 b 3 66
...
mknod -m 660 /dev/hdb8 b 3 72
