CCBB maintains 3 clusters:
- phylocluster is a general purpose cluster; for access permissions please contact David Hillis.
- chencluster is for use by the members of the Chen Lab; if you do not have account please have Jeff Chen confirm you are a member of his lab.
- ceres is primarily for use by the Wilke Lab members; if you do not have an account, please have Claus Wilke confirm you are a member of his lab, or otherwise have his permission to have an account.
=== phylocluster ===
Our general purpose cluster, phylocluster, is a 15 node cluster running ROCKS v 4.1. The head node, phylocluster, has 2 Intel Xeon 2.80 Ghz CPUs with 2 GB of RAM. There are two main data areas for users. /state/partition1 is 140GB unRAIDed storage space used for some home directories. /state/partition2 is 135 GB, and uses software based RAID for redundancy. Most new user accounts are now created to use /state/partition1.
The 15 nodes in phylocluster are Dell PowerEdge SC1425 1U units. Each system has 2 Xeon 3.20 Ghz dual-core CPUs, and 2 GB RAM. Each node also has a 36 GB Seagate ST336754LW SCSI disk attached to the system via an Adaptec AIC7902 Ultra320 SCSI adapter. The bulk of this disk - 27 GB - is used for /state/partition1 which is available for temporary storage of files.
=== chencluster ===
The Chen Lab cluster, chencluster, is a 47 node cluster run ROCKS v 4.5. The head node, chencluster, is Dell 2850 with two dual core 3.20 GHz processors. Internally it has 200 GB of storage, and internally it has 1.5 TB storage on an external S2A 3000 fibre channel disk array.
The 47 nodes in chencluster are Dell 1850's with two dual core 3.20 Ghz CPUs with a Maxtor Atlas 36 GB 15K RPM, leaving 27 GB for local storage.
=== ceres ===
The Wilke Lab cluster, ceres, is a 17 nodes cluster running ROCKS v 5.0. The head node, a Dell PowerEdge 2950 2U system, has two Intel Xeon X5355 2.66 quad-core CPUs, and 8 GB of RAM. The system has 6 500 GB uSATA drives attached to a PERC 5/i RAID card. The drives are arranged in a RAID 5 configuration with 1 hotspare adding up to 2.0 TB of storage.
The 17 nodes are each Dell PowerEdge 1950 1U systems have 2 Intel Xeon X5355 2.66 Ghz quad-core CPUs with 8.0 GB of RAM. The nodes each have individual 73 GB 15K RPM SAS drives. This provides 55G of temporary storage space on /state/partition1.
== Data Storage ==
CCBB currently has no centralized storage. Depending on which lab you are in, or what cluster(s) you have access to you will have access to large amounts of storage space. Due to the security requirements of such systems, '''NO''' CCBB systems are qualified to store Category I data. At most research data, or other personal files should be stored on CCBB systems. If you need to store sensitive, private data you need to do so securely. The easiest way to do this is to use an http://www.utexas.edu/its/services/storage/ ITS data storage solution such as Austin Secure Disks, or WebSpace.
== Networking ==
=== Wired ===
CCBB has a number of wired connections which should already be connected to the network. However, some jacks may be connected to one of our private networks. If you cannot get access to the network, please let us know what jack number you used. All jacks provide 10/100 MB ethernet.
=== Wireless ===
The wireless networking is provided by an antenna in PAT 141. All wireless
access points at UT MUST be provided and maintained by ITS T&N. No other wireless
access point is authorized. Please do not violate this rule; doing so is an extreme security risk. Two networks are provided. Unless otherwise
exempted all wireless clients are expected to use the Restricted network
which requires a WPA2 login using your UTEID. If a client cannot be
configured to work on the Restricted, an exemption can be granted
allowing it to use the older Guest network. See a member of the computing staff for help doing this This requires a browser
session to be started, and an attempt made to access a non-UT URL, at
which point the user will be required to log in. Guest is a misnomer;
not-UT visitors who really are guests will need to have temporary accounts created for them. If you are hosting a visitors, and they will need wireless access, please stop by and have an account created. The Restricted/Guest network restriction is typically lifted at the start of the Fall semester, so that new students, and faculty will not be cut off from the network. This typically ends on the 12th class day.
ITS Telecommunications and Networking is
currently working to select a vendor to provide pay for use wireless similar to that in coffee shops, bookstores, and restaurants. The intent is this would be used by visitors who are here only for a short time, but who are used to having wireless access where ever they go. For UT related people, use of that network is optional, but it might be an easier way for guests in a hurry to get access to the network. A pilot program will be run starting in mid-June during which our two vendors will be given networks at UT. Therefore, do not be alarmed when you see extra networks called AT&T and Boingo come and go over the summer. With these networks, nothing changes. Wired access to the network will still be allowed. Students, faculty, staff, and official visitors should continue to use the Restricted network. Non-official visitors who are here for a short time can be brought to PAT 141SC for accounts on the guest network, so long as someone is willing to sponsor their activities. However, if it's more convenient, or if you are unwilling to sponsor your guest(s), they are free to use the paid service.
=== VPN ===
UT provides a virtual private network, or VPN, used to connect to secure services on campus. Depending on which lab you work in, certain systems may not be accessible unless you use the VPN. Certain other secure UT provided services may also be inaccessible. The VPN is simple to use; clients for both Mac, and PC can be downloaded from http://www.utexas.edu/its/bevoware Bevoware. Use of the VPN is restricted to faculty, staff, students, and official visitors. More information about the VPN can be viewed at the http://www.utexas.edu/its/vpn/index.php ITS VPN page.
