All users with active accounts on any TACC HPC or SciVis system automatically have an account on the data archive. Currently, there is no quota for user accounts on the archive system.
If you are interested in a storage allocation on the data archive but do not need an HPC or SciVis account, please email info@tacc.utexas.edu.
Sun Microsystems® StorageTek Mass Storage Facility: Ranch
| System Name: | Ranch | |
| Host Name: | ranch.tacc.utexas.edu | |
| IP Address: | 129.114.50.81 | |
| Operating System: | Linux | |
| Total Disk: | 2.5 PB uncompressed data (5000 tapes/ 32 TB disk cache) | |
| Description: | ||
TACC's long-term mass storage solution is a Sun Microsystems® StorageTek Mass Storage Facility, nicknamed Ranch. Ranch utilizes Sun's Storage Archive Manager Filesystem (SAM-FS) for migrating files to/from a tape archival system with a current storage capacity of 1 PB.
Ranch's disk cache is built on a Sun ST6540 disk array containing approximately 32 TB of spinning disk. This disk array is controlled by a Sun x4600 SAM-FS Metadata server which has 16 CPUs and 32 GB of RAM.
A single Sun StorageTek SL8500 Automated Tape Library houses all of the offline archival storage. Each SL8500 library contains 10,000 tape slots and 64 tape drive slots. Each tape is capable of holding 500 GB of uncompressed data, so when fully populated, a single SL8500 library can house 5 PB. Each SL8500 library also contains four handbots to manage tapes and move them to/from the tape drives. If necessary, up to four SL8500 libraries can be integrated into a single archival solution, allowing for an offline storage capacity of 20 PB.
The current ranch configuration has 5,000 tapes, and is capable of housing 2.5 PB of uncompressed data. However, future plans call for further population of the tape slots as well as upgrades of the physical media from 500 GB capacity to 1 TB capacity.
For more information about using Ranch, see the Ranch User Guide.
Data Direct Networks/Dell Data Applications Facility: Corral
| System Name: | Corral | |
| Host Name: | corral-login.tacc.utexas.edu | |
| IP Address: | 129.114.52.140 | |
| Total Disk: | 1.2 Petabytes raw capacity | |
| Description: | ||
Corral is a new system deployed in April 2009 by the Texas Advanced Computing Center to support data-centric science at the University of Texas. Corral consists of 1.2 Petabytes of online disk and a number of servers providing high-performance storage for all types of digital data. It supports MySQL and Postgres databases, high-performance parallel file system, and web-based access, and other network protocols for storage and retrieval of data to and from sophisticated instruments, HPC simulations, and visualization laboratories. A high-performance parallel file system based on Lustre will be made directly accessible from TACC's world-class computational resources, Ranger and Lonestar, as well as Stallion, the world's largest tile display, enabling both mathematical and visual analysis of petabyte-scale datasets.
Storage Area Network: SAN
The TACC Storage Area Network (SAN) is intended to provide the user community a high-speed, shared storage facility that is available to all TACC computational and visualization resources. Currently the SAN is managed by a Sun V880 server configured with 8 UltraSPARC III processors, 16 GB of memory, and the Sun UFS file system. Approximately 5 TB of Sun T3 storage is shared among the TACC computational resources and available to each resource at Fibre Channel speed. This true file sharing is accomplished via software running on the V880 in conjuntion with Tivoli SANergy client software running on the computational resources, Fibre Channel interfaces in the V880 and client systems, and a Fibre Channel network fabric based on a 64-port QLogic switch.
For more information about using SAN, see the appropriate User Guide.
