ASM was originally part of the i7 cluster, made up of other machines named after other programming languages. At the beginning of the 2017-2018 school year, ASM was repurposed by 2017wzhang to be his personal workstation (at school). By the end of the 2017-2018, only ASM remained in the CSL as all the other gutted motherboards of the i7 cluster had been taken home by other sysadmins.

During the [Cephpocalypse](../history/2018-cephpocalypse.md), ASM was used as a place to put exported Ceph images, largely due to its fast (~10MB/s) uplink, ease of logging in as root, and large hard drive size. People were outraged when 2019jduvall accidentally cut ssh access to it in the middle of the crisis (I'm sorry, ok?).

# VM Servers
22

3+
**VM Servers** \(also known as VM hosts\) host virtual machines for the various CSL services we maintain. The VM Servers themselves run off a local hard disk \(often in a RAID configuration?\).
4+
5+
## Reasoning
6+
7+
Although VM servers have existed for multiple years in the Lab, complete virtualization of critical services occurred the summer of 2017. The reason for this was to allow services to be brought up quickly. In addition, our current VM setup permits us to bring up new machines more quickly and fully utilize [RBD block storage as our storage backend](../ceph/).
8+
9+
## Exceptions
10+
11+
Various services are not virtualized at this time and probably should never be.
12+
13+
* [NTP](../../technologies/ntp.md) is an extremely critical machine since it provides time for the whole Lab.
14+
* [ns1](../../technologies/networking/dns/) is not virtualized because it provides DNS to not only VMS but also to the main Ceph backend
15+
* [centauri ](../sun-servers/centauri.md)is not virtualized because it provides critical authentication services to the rest of the Lab \(and also the VM hosts themselves\)
