The Tertiary Education Network (TENET) has established a large mirror server to share content with both local and international users.
The new server, hosted at http://www.mirror.ac.za/ , boasts some of the most impressive specifications in the local Internet environment.
The server comprises of an internal array of six 400 GB disks, and three external arrays of twelve 500 GB disks each. The arrays are all configured in raid-5 with hotswap for redundancy, and the total active disk space after raid loss is in excess of 13 terabytes.
The machine itself is a dual Xeon system running dual core processes and 4 Gigs of RAM. The system runs Solaris 10, primarily for the ZFS file system.
This server is hosted on the TENET backbone, and with approximately 50 Mbit of national bandwidth and 180 Mbit of international bandwidth it is well resourced in a local Internet context.
“The server will give preference to our own customers with regards to their own transmission needs of course, but generally there is plenty of outbound bandwidth available to service the general community,” said Andrew Alston, CTO of TENET.
And this bandwidth is definitely not wasted when looking at the amount of content served.
“The Mozilla.mirror.ac.za mirror which is in the global download rotation for Mozilla, Firefox and Thunderbird currently averages about 700 Gigs a day of outbound data, though we have peaked at about 1.2 terabytes in a single 24 hour period on release of a new version,” said Alston.
At this stage the system mirrors various Linux flavours, MIT Open Courseware and some other content, and TENET said that they are looking to expand on the current shared content. Requests can be sent to email@example.com
