SAN Probe FCX
NetWisdom Fibre-Channel Probes (ProbeFCXs) analyze every
packet on a fibre-channel SAN at line rates up to 4 Gbits per second.
Each ProbeFCX contains up to 8 probes, and each probe is able to monitor
in real-time in both directions of a single SAN link. A ProbeFCX probe
can be dedicated to a single SAN link or, using a physical-layer switch
(PLS), can rove among many SAN links to provide statistics about storage
traffic to an application, storage subsystem, remote replication, virtualizer,
or other key SAN devices or applications.
ProbeFCX probes detect application performance slowdowns by measuring
every SCSI I/O transaction from start to finish, for both reads and writes.
Exchange Completion Times (ECT) metrics are maintained for every server/volume
combination (initiator/target/LUN). Latency through WANs and from servers
to storage subsystems are measured. A baseline of all of these metrics
can be created to verify that there are no impacts after server OS or
device firmware upgrades, zone modifications, or other changes to the
SAN.
Failing SCSI devices may be proactively detected by monitoring link errors
and SCSI operation errors. Congested storage ports can be identified from
the ProbeFCX queue depth metrics, which are measured by monitoring the
number of active and pending SCSI exchanges to the same target port. ProbeFCX
probes also detect and track fibre-channel and SCSI protocol faults.
Finisar's ProbeFCX is connected through Finisar's High-density TAPs. The
probe gathers all of the transactions at the Initiator/Target/LUN level
(host to storage conversations), providing detailed statistics on the
SAN's health and performance. These real-time Fibre Channel and SCSI metrics
are sent to the NetWisdom Portal every one second for reporting and further
analysis.
A summary of changed metrics is reported to the NetWisdom Portal by the
ProbeFCX probes every second, via an Ethernet connection.
