[mythtv-users] Dedicated backend

[Josu Lazkano]

Hello list, I am running MythTV for 3 years on two different
frontend/backend ION systems. They work great, but I want to try to
add a dedicated backend and use it from differents frontends.

I buy a "HP ProLiant MicroServer AMD Turion II N40L":

I will add to it 4 tuners:

PCIe DVB-S2 Tevii S470
USB DVB-S2 Tevii S660
USB dual Hauppauge DVB-T

It comes with 2GB of memory and a 250GB disk. I will add an other 2TB
SATA and 2x1TB SATA (RAID 1).

My idea is to use the 250GB disk as system (EXT4), the 2GB disk for
recordings (XFS) and both 1TB disk as personal data on a RAID 1
(EXT4).

My favourite distro is Debian, so I plan to install Debian Wheezy 64bits on it.

My questions:

1. Is a good option to install 64bits? I always use 32bits.
2. Do you recommend to add a special filesystems? for mysql, for recordings...
3. Any other advice?

I will appreciate any help.

Thanks and best regards.
