Dirtycow is VTLUUG's 3rd(?) generation NFS server. It replaces [[Infrastructure:Cyberdelia]] and hosts storage for our more critical services. It is currently running Ubuntu 18.04.

Dmesg indicates it is a Dell PowerEdge 2900 III with board model of 0NX642<ref>http://www.dell.com/downloads/global/products/pedge/en/pe_2900_III_spec_sheet.pdf</ref> with 24GB DDR2 RAM clocked at 667MHz.

It has 2 4-core X X5404 @ 2.00GHz<ref>http://ark.intel.com/products/34446/Intel-Xeon-Processor-X5450-12M-Cache-3_00-GHz-1333-MHz-FSB</ref><ref>https://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+X5450+%40+3.00GHz&cpuCount=2</ref> and up to 8 hot-swap SCZI(SAS?) hard drives, with an additional 2 SATA ports. The drives are configured with 8 2TB drives and 2 120GB drives. The 8 identical drives are mounted in a ZFS-raidz2 array. The remaining 2 SSDs are configured with raid 1 and have a single root partition.

The ZFS pool has a total capacity of 14.5T, of which 5.15T are allocated (as of Jan 2019).

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

== Storage ==
The following datasets are configured:
* /cistern/backups - Important backups
* /cistern/nfs/docker/data - Persistent docker data volumes
* /cistern/nfs/files - https://vtluug.org/files
* /cistern/nfs/home - User homedirs for IPA users, available over NFS to VTLUUG hosts
* /cistern/nfs/libvirt - Storage for libvirt hosts
* /cistern/nfs/scratch - Temporary unimportant storage
* /cistern/share/srv - Webserver dir for Sczi, but not used since we've migrated everything to docker
