Infrastructure:Meltdown

2024-10-31T20:41:40Z

Botjoe: /* VMs hosted */

Meltdown is VTLUUG's 3rd generation VM server. It replaces [[Infrastructure:Cyberdelia|cyberdelia]] as a VM host for our more critical services. As of 2019 it also serves as a docker host, however, all web services still run on [[Infrastructure:Sczi|sczi]]. It is currently running Ubuntu 18.04.

It is a Dell R620, purchased in Spring 2018 as part of [[Project Bringing Sexy Back]] (along with [[Infrastructure:Spectre|spectre]]).

It has 2 12-core Intel Xeon E5-2620 @ 2.00GHz, with 64GB DDR# RAM, clocked at (???).

It has 4 NICs, support for up to 4 hot-swap SCSI/SAS drives. The disks are configured with 2 280GB drives in raid 1 with LVM setup on it. Within LVM it has a root partition formatted as ext4 and a docker partition formatted as xfs to enable the --storage-opt option in docker.

It resides in the ECE Server Closed in [[Whittemore]].

== VMs hosted ==
Meltdown hosts all non-user VMs. User VMs are stored on [[Infrastructure:Spectre|spectre]].
* [[Infrastructure:Chimera|chimera]] - FreeIPA server
* [[Infrastructure:Sczi|sczi]] - Web server
* [[Infrastructure:Acidburn|acidburn]] - Shell & Mail server
* [[Infrastructure:Nikonwormhole|nikonwormhole]] - DNS redirect
