QLogic’s Gen 5 Fibre Channel isolated dual-port designed architecture
delivers:
•
Independent Functionality – reset or error recovery on one port does
not impact performance of the other port
•
Higher Reliability – Firmware crash on one port does not crash the
other port
•
Better Security – isolation at the physical level; Physical Function (PF)
for one port cannot access state information (registers, memory info,
etc.) of another PF due to physical isolation
•
Predictable Performance – i/O spikes on one port do not affect the
performance of the other port
•
Enhanced Scalability – the QLogic dual-port adapter has better
scalability than competitive offerings when traffic on the second port
is added
test results show that the QLogic adapters outperformed the competitor’s
adapters; the QLogic adapters provided higher bandwidth and faster
completion of database workloads, as well as secure, predictable, and
scalable dual-port architecture.
the QLogic 16Gb dual-port adapter scales linearly and delivers twice the
performance compared to its own single-port adapter. the competition’s
shared architecture does not have the capacity to scale its dual-port
adapter compared to its single-port adapter.
the tests found that for the tPC-h workload:
•
Moving from QLogic 8Gb to QLogic 16Gb Gen 5 Fibre Channel improves
tPC-h performance by up to 82 percent for some queries and increases
the overall tPC-h full run by 35 percent.
•
the QLogic 16Gb adapter delivers double the transactional performance
for Oracle OLtP environments.
