Hi All,
I am about to setup a personal data server on some decent hardware (1u
SuperServer, Xeon, LSI SAS controller, SAS backplane). Well at least,
it's decent hardware to me. :)
After reading Richard's blog post, I'm still a little unsure how to
proceed.
Details:
- I have 8 drives to play with on the systems backplane;
- Reliability over performance (320G 2.5" 5400 RPM SATA drives)
- High-availability is not required, but I want the data to be as safe
as possible (real backups will be infrequent and difficult)
- Potentially, I can add a ninth SATA drive by using some fancy
bracket to replace the slim DVD that will be hard to source
These are the options I have figured out so far:
1. 2 mirrored drives for the root pool, 6 drives in raidz2 for the tank
2. 4 pairs of mirrored drives for a single pool that would also be
root, but I think I can't boot from that, right?
3. 1 non-redundant drive for root pool, 7 drives in raidz2 for the
tank, backup the root pool regularly
4. Use a CompactFlash card (the board has a slot) for root, 8 drives
in raidz2 tank, backup the root regularly
5. Figure out how to have only the kernel and bootloader on the CF
card in order to have root on the raidz2 tank
5.5. Figure out how to have the kernel and bootloader on the CF card
in order to have 4 pairs of mirrored drives in a tank, supposing #2
doesn't work
Comments, suggestions, questions, criticism?
Thanks,
A.
