Accessing Beagle
The fully qualified registered name for beagle is
beagle.rnet.missouri.eduIn order to log in to beagle, you must use a client that supports the SSH version 2 protocol. Telnet access is not allowed. Windows users can download the SSH Secure Shell program from this site. SecureCRT and PuTTY are examples of other Windows programs that support the SSH version 2 protocol. If you use a Unix workstation, you will need to install/upgrade to SSH version 2 if you have not already done so.
The following restrictions are in effect when accessing beagle:
-
Telnet access is not allowed. You must use an SSH version 2 client.
-
Access via rsh, rlogin, and rexec are not allowed.
-
FTP connections from remote systems into beagle are not allowed. Remote file transfer connections must be initiated
using a secure FTP (SFTP) client program that authenticates to the server using SSH version 2. Unix systems with SSH version 2
installed can execute the sftp program. The SSH Secure Shell program for Windows available from this site also supports
SFTP.
- There is no anonymous FTP on beagle.
You must submit long-running jobs to the PBS batch queuing system. The PBS scheduler will automatically execute the jobs, based upon availability of resources and system load. For information about how to submit jobs to PBS, see Submitting Jobs via PBS.
- Compaq/HP AlphaServer SC
- The AlphaServer SC system consists of two AlphaServer ES45 nodes. Each node has 4 1-GHz Alpha processors and 4 GB of RAM. A high-speed Quadrics switch connects the nodes. Each node has both a 10/100BaseTX Ethernet adapter and a 1000BaseSX gigabit Ethernet adapter for external network connections on the MU Research Network.
- A dual processor AlphaServer DS20 acts as a management server for the AlphaServer SC complex. (User jobs do not run on the management server.)
- Data Storage Resources
-
The primary data storage resources on beagle reside on a Fibre Channel
SAN with two dual-controller Compaq/HP HSG80 controllers. Each of the
two beagle nodes has direct access to the SAN via dual Fibre Channel
host bus adapters.
-
There are approximately 3.8
terabytes (unformatted) of disk space on the SAN available for
applications, databases, user files, and temporary work file
space. The disk array contains:
- 60 36-gigabyte disks
- 24 72-gigabyte disks
- All of the disks used for applications, databases, user files, etc. are configured into RAID 5 sets. The disks used for temporary work file space are configured into a non-redundant stripe set for better performance.
