RE: [Xen-users] hardware recommendations please
I don't understand why thLOM thing is any different to the IPMI+KVM
over IP offered by many manufacturers.
Is there anything significant in ILOM that is additional to the list of
out of band features built into a Tyan I'm using now?:
Sensors (Voltage, Fans and Temps and PSUs)
Full Colour KVM over lan
System power control
Mount CD, DVD and FD images for boot or use in OS
SNMP and traps for log events
Serial console to com1 over lan
Full sys log
HTTP, HTTPS and IPMI 2.0 interfaces
I find IPMI perfectly reliable (Have used plenty of system with IPMI but
no KVM over IP), mainly used for power cycling a hard locked system,
getting console to enter bios/raid bios and occasionally checking sensor
readings. It is a pain to remember that IPMI console access needs to be
added to the Linux grub config or Windows boot.ini which is why KVM over
IP is best.

Hm, ILOM is default gear on every sun x86 Server. Also ILOM can do a
thousands more things, it sends you an email if a DIMM or whatever
fails, it allows you access to RKVM and serial console (webui and ssh)
and allows you to remote mount boot media. I use two x4150 here with
opensolaris xvm, I really seldom need to enter the server room, without
any additional requirements.
