Re: What SATA controller for software raid and/or lvm?

["Joël Bourquard" <numlock@freesurf.ch>]

Hi,

It seems we have the same priorities :-)

However, before I rush and order these two Highpoint 1820's ($300), it
may be wise to ask the linux serial-ata specialist:

Jeff Garzik
jgarzik@pobox.com

I'll e-mail him tomorrow. May I provide your e-mail address to him ? He
was skeptical about Highpoint's linux support, but maybe things have
changed since 2/1/2004 (when Highpoint posted an opensource module for
the 1820 controller).

Building the server is a priority to me, but I must wait for a few days
anyway (Paypal refuses a transaction, when it shouldn't).

Anyway, if we can get a definitive word about this controller, I think
it might help a lot of people on Linux-RAID... I mean, a 64-bit 133MHz
SATA controller with 8 ports, for about $150 is really nice :-)

So.. if you're still interested, please let me know what you think,
before I e-mail Jeff.

Best Regards,
Joël
