Fig. 1. The system is an integrated solution
from five contributing companies incorporating a tape robot, hierarchical system
management (HSM) software and seismic data management system (SDMS) software. In
addition, a Sun E4500 with a 150 GB RAID disk array was incorporated into the system
as a staging server.
Panther Software Corp.s SDMS software
application provided the unification of individual system components. SDMS integrated
all aspects of seismic data management, including initial data preparation and quality
control, data loading to application formats, centralized metadata cataloging and
project management functions.
All forms of seismic data managed by SDMS are
referenced in the database by unique spatial location, with detailed information on
data types, project location and data attributes available for each of the individual
versions of an original dataset existing on the system. Database information can be
accessed and queried via the map front end with a point-and-click selection process
for direct loading of SEG-Y trace files into interpretation applications. SDMS also
enables integration of detailed seismic information through access to other data types
via tools such as OpenExplorer.
Large Storage Configuration Inc.s SAM-FS
software product is an HSM tool which proactively manages online / nearline storage
according to user-established flexible business rules. In addition to providing
complete copies of all online file systems, the system releases online disk space as
disk utilization approaches a user-designated, high-water mark.
Files released from online disk storage are quickly
retrieved from nearline tape storage via a user-controlled GUI. Business rules are
programmed such that all related project files are both released from the online disk
system together and restored from nearline storage when called.
Sony Electronics Inc.s PetaSite tape
robot is a scaleable data storage system providing up to 2,000 TB storage capacity on
industry-standard DTF tapes utilizing multiple, modular tape drives. Conoco chose an
initial configuration of 5.4 TB, combined with its existing 2.2 TB of online storage,
to address current and future scalability needs. The robot incorporates high-capacity
tape technology (42 GB per tape) with high-speed data-streaming capability (11 MB/sec)
designed to accommodate the unique demands of seismic data management.
The robot is expandable via tape and tape drive
modules that are easily attached to the existing system. The next version of DTF tape
technology will increase individual tape capacity to 200 GB and data-stream rate to 24
MB/sec. All upgrades in drive technology will be backward-compatible to protect
customer investment.
Ovation Data Services, Inc. provided system
integration expertise to ensure that combined software / hardware components
functioned as a single system. The collective system was configured / tested at a
data-service facility prior to delivery. Specialized customization required for
integration with customer environments, such as Conocos Auspex disk servers, was
performed during this process to simplify client implementation.
Sun Microsystems Inc.s server technology
provided the computing platform base for the system. SDMS application and SAM-FS
software were both developed for Suns Solaris environment. Servers of all sizes
were available for integration with the system according to client requirements.
Appropriate server selection was defined during the initial system design and
configuration process to ensure optimal system performance. In this case, the client
required a Sun E4500 with a 150 GB RAID disk array, incorporated into the system as a
staging server. |
