Devices layer

The devices layer relates to the disk and controllers that store your data. Adaptive Server can manage a virtually unlimited number of devices.

Issues at the devices layer include:

Address these issues by:

NoteAdaptive Server devices are mapped to operating system files or raw partitions, and depend on the performance of the underlying physical devices and disks. Contention can occur at the operating system level: controllers can be saturated and the disks organized under storage area network logical unit numbers (SAN LUNs) can be over-worked. When analyzing performance, balance the physical load to properly distribute load over operating system devices, controller, storage entities, and logical unit numbers.
