The Anxur server runs on a computer in the configuration:

• 4 20-core Intel® Xeon® CPU Platinum 8180 processors running at 2500 MHz (turbo 3800 MHz)
• Each core has 1 MiB L2 cache
• Each processor has 38.5 MiB of shared L3 cache
• Two 800 GB NVMe drives in a RAID1 configuration, sixteen 3.84 TB SSDs and fifty-four 12 TB HDDs in a RAID 10 configuration, for a total of more than 60 TB of SSD and 640 TB of HDD logical capacity; see also blog post on disk array upgrade
• 1.5 TB OF RAM

Services

The Anxur server serves as a staff SSH server - it is analogous to the Aisa student server. It provides email systems management (mail receiving, mail sending and spamfilter) for PhD students and staff, disk space for home directories and user web pages available at www.fi.muni.cz/~login/ and backups.

Depending on the type of key used, the machine key fingerprint that the client will ask for authenticity when first connecting via SSH is one of the three below. These fingerprints changed in September 2024 when the server was upgraded to the following:

• ED25519: SHA256:xBi2F9888UvdcbZNkmmhTg7GWIqaivF6u6TGI7dtX6M
• ECDSA: SHA256:bu79ADQRplyljiYW1Yi9UjFZkAnM4vVjB99SinEvD+I
• RSA: SHA256:1N7FURnShMwL5R4TxYim1Ia6qkuJFdkT9mMImvrsKIE

Origin of name

Anxur (2nd fall of Anxur) - god of the underworld among the Italian tribe of the Volsci, later identified by the Romans with the supreme god Jove. Anxur was worshipped by the Romans under the name of Juppiter Anxur. His cult had its main centre in Terracina (southeast of Rome), which was called Anxur in the time of the Volscians.
