is eligible for zHPF and sees a
more substantial 22 percent
improvement in I/O service time.
The multistream read performance improved 39 percent and
the multistream write performance
improved 34 percent. Single
stream read and write performance
improved about 20 percent for each.

DB2 database updates are first
written to the log and committed when log writes complete.
zHyperWrite with FICON
Express16S has a substantial
improvement to DB2 commit
latency up to 61 percent. FICON
Express16S technology alone can
provide up to 23 percent improve-

ment in the DB2 log write I/O
service time, also a substantial
improvement.
During batch windows, client workloads typically make
simultaneous large read/write
I/O requests. For I/O bound
jobs-meaning those that wait on
I/O requests to proceed-FICON
Express16S can reduce the elapsed
time by as much as 25 percent.
The combination of the z13
FICON Express16S technology
and the DS8870 16GFC HA
provide substantial I/O latency
reductions for zHPF I/O traffic.

IBM field experience has shown
that faster fiber channel link
speeds are more sensitive to optical cabling infrastructure quality.
