By doubling the hardware, you still do not overcome the potential corruption that could occur with non-ecc memory. If this is truly a mission critical application then it really does not serve much of a purpose to short change yourself with substandard hardware. -----Original Message----- From: centos-bounces at centos.org [mailto:centos-bounces at centos.org] On Behalf Of John R Pierce Sent: Sunday, February 13, 2011 7:17 PM To: centos at centos.org Subject: Re: [CentOS] server specifications On 02/13/11 7:06 PM, Nico Kadel-Garcia wrote: > It's also possible to save the budget, buy *two* similarly powerful > used systems with much lesser hardware specs, and have genuine > failover instead of the shared vulnerability of one expensive server > with high-availability components as you describe.
