This is getting OT and you are going to end up spending more on redundancy then if you just called Dell and ordered another computer. ----- Original Message ----- From: centos-bounces at centos.org <centos-bounces at centos.org> To: CentOS mailing list <centos at centos.org> Sent: Fri Mar 14 09:31:00 2008 Subject: RE: [CentOS] Recommendations for a “real RAID" 1 card on Centos box > That is true, buy high quality stuff up front for fewer problems down > the road.

So for a top quality power supply for a mission critical desktop machine, which brand(s) would you reccomend? One of the towers I have is a Thermaltake Xaser 3 with lots of room, and I just bought a new Antec Sonata III tower with a 500 watt PS. > So BBU is certainly a nice thing to have but at least in my > experience isn't absolutely critical. Then for a Mission critical desktop machine, if you had to make a choice, would you go with a good quality UPS and/or redundant power supplies, or a BBU instead? > Of course for absolutely critical things I don't use server-based > RAID anyways.

As an alternative to RAID1 for a mission critical desktop machine @ home, what would you reccomend? Maybe a bare metal restore solution able to restore to different hardware, (i.e. if a motherboard dies and drive crashes due to power spike or some catastrophe, I'm screwed if I can't find the exact same make - model)? _________________________________________________________________ Connect and share in new ways with Windows Live. http://www.windowslive.com/share.html?ocid=TXT_TAGHM_Wave2_sharelife_012008_______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.
