network and stability issues
by Karanbir Singh 01 Nov '12

01 Nov '12

hi Guys, Over the last 24 hours we have had a series of stability issues. First, the DC our mail/lists machine is hosted in had power issues ( Internap LGA9, NY, USA ); then we had a h/w failure and needed a chassis swap ( thanks to the guys in the DC who executed this within minutes ); and we have since again had network issues - although power to the DC and the server seems stable now. Over the next 24 hours, lets just try and be a bit patient and work with this. We have good backups so if things dont stabalise in the next 24 hrs we will failover. The primary reason we have not done this as yet ( failover ), is down to the fact that its taken a long time, in years, for us to build a reputation with large hosting facilities and email providers and are on many whitelists. Moving the host over makes it hard for us to get that sort of level of trust again really quickly. Longer term, we should perhaps spread the load through multiple machines and then ensure we have good relationships out of all these machines exit IP's with the various vendors and service providers. There are backup MX's in place, so if there are issues with the primary machine, we will have mail's go into holding queues and we should not lose anything inbound. -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh ICQ: 2522219 | Yahoo IM: z00dax | Gtalk: z00dax GnuPG Key : http://www.karan.org/publickey.asc

Virtualization Options!
by Antonio da Silva Martins Junior 01 Nov '12

Hi, I'm searching for "virtualization options". I already take a look on VMware, but it needs too much MS software to work for my needs. Citrix needs less, but the key validation is still MS-AD. Now I'm taking a look at RHEV... and run into Oracle VM! Somebody had already take a look at Oracle VM? We need in primary a solid VM solution for an "enterprise cloud" running on top of some old and new Dell servers in conjunction with an EMC Cx4-120 storage. We had plans to provide "desktop virtualization" in the future, most to labs class, and maybe adminstrative tasks. But it isn't necessary now. Anybody had some other options to tell? Thanks in advance, Antonio. -- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Antonio S.
