If an active disk object becomes unavailable due to a path failure, APS automatically switches to the Secondary Disk Object that represents an alternate data path
through the SAN to the LUN in the storage array (Fig 4).
a redundant data path
generator that allows users to input a single stream of data into one port and then output identical data streams at variable data rates on each of the other ports for fault tolerance;
Architected for wire speed 10 Gb bandwidth using inexpensive DDR memory, this new family of devices has up to 14 on-chip engines: 12 in the data path
, 1 MIPS core in the control path, and 1 MIPS core for either the control path or the data path
Putting security directly in the main data path
and offloading the compute-intensive IPsec protocol from the network processor makes OC-48 performance for encrypted traffic not only a viable option but also an affordable one.
To address the availability issue, some server appliances are implemented "out-of-band", providing virtualization and management capabilities out of the primary data path
Each custom processor within the RAID Storage Processor has its own dedicated memory and data path
for code fetch, virtually eliminating interrupts.
However, increased demands on storage systems created by content-rich applications, the expanding volume of transactions, and the migration to higher link speeds have created compute and data path
requirements that architectures centered on general purpose microprocessors can no longer meet.
By packaging two independent Variable Gain EDFA stages within a single module and interconnecting the pre-amplifier stage from one module (East or West) to the booster stage from a second module (West or East), the RED-C Sentior 27000 ensures that each data path
(normal and protection) depends on only a single module, and not on both modules.
The data path
between clients and storage arrays is a journey across diverse networking devices and I/O busses.
The multi-threaded data path
offers the dramatic packet throughput improvements plus carrier-class QoS, integrated VoIP and superior security that our customers demand.
With its position in the center of the data path
, the network storage controller must be purpose-built in order to have the levels of performance and reliability, availability and serviceability (RAS) that are typically found in monolithic storage devices.
