November 5, 2008 - Pillar Data Systems announced the availability of 450GB 15,000 RPM fibre channel drives for the Pillar Axiom 600. The new disk drives add 50 percent more fibre channel capacity to the Axiom, all of which is backed by Pillars 80 percent utilization guarantee.
The Pillar Axiom has the ability to offer two types of data migration functionality that fully leverages the differing characteristics of fibre channel and SATA drives. The first mode of data migration is permanent, where infrequently accessed or non-critical data is transparently moved to lower cost, higher capacity SATA drives. Conversely, mission critical, often accessed data is stored on the higher performance, fibre channel drives.
Temporary data migration functionality in the Axiom allows for dynamic reassignment of quality of service (QoS) levels based on the real-time need of the application. For example, in a database being created for transaction processing, the level is set accordingly to allow for optimal online transaction processing (OLTP); however, the initial load of the data is a sequential operation. The database can be created in the proper QoS setting for OLTP, and then the QoS level can be temporarily changed to high performance write sequential bias to make the initial load operation much faster. Once the initial load is completed, the QoS setting can be reverted back to the original, optimal QoS setting.
