IBM Z10 EC - Manual (Page 19)

ESCON Channels
The z10 EC supports up to 1,024 ESCON channels. The
high density ESCON feature has 16 ports, 15 of which can
be activated for customer use. One port is always reserved
as a spare which is activated in the event of a failure
of one of the other ports. For high availability the initial
order of ESCON features will deliver two 16-port ESCON
features and the active ports will be distributed across
those features.
Fibre Channel Connectivity
The on demand operating environment requires fast data
access, continuous data availability, and improved fl exibil-
ity, all with a lower cost of ownership. The four port FICON
Express4 and FICON Express2 features available on the
z9 EC continue to be supported on the System z10 EC.
Choose the FICON Express4 features that best meet
your business requirements.
To meet the demands of your Storage Area Network (SAN),
provide granularity, facilitate redundant paths, and satisfy
your infrastructure requirements, there are three features
from which to choose.
Feature FC # Infrastructure Ports per

FICON Express4 10KM LX 3321 Single mode fi ber 4
FICON Express4 4KM LX 3324 Single mode fi ber 4
FICON Express4 SX 3322 Multimode fi ber 4
Choose the features that best meet your granularity, fi ber
optic cabling, and unrepeated distance requirements.
FICON Express4 Channels
The z10 EC supports up to 336 FICON Express4 channels,
each one operating at 1, 2 or 4 Gb/sec auto-negotiated.
The FICON Express4 features are available in long wave-
length (LX) and short wavelength (SX). For customers
exploiting LX, there are two options available for unre-
peated distances of up to 4 kilometers (2.5 miles) or up
to 10 kilometers (6.2 miles). Both LX features use 9 micron
single mode fi ber optic cables. The SX feature uses 50
or 62.5 micron multimode fi ber optic cables. Each FICON
Express4 feature has four independent channels (ports)
and can be confi gured to carry native FICON traffi c or Fibre
Channel (SCSI) traffi c. LX and SX cannot be intermixed on
a single feature. The receiving devices must correspond to
the appropriate LX or SX feature. The maximum number of
FICON Express4 features is 84 using three I/O cages.
FICON Express2 Channels
The z10 EC supports carrying forward up to 336 FICON
Express2 channels, each one operating at 1 or 2 Gb/sec
auto-negotiated. The FICON Express2 features are avail-
able in long wavelength (LX) using 9 micron single mode
fi ber optic cables and short wavelength (SX) using 50 and
62.5 micron multimode fi ber optic cables. Each FICON
Express2 feature has four independent channels (ports)
and each can be confi gured to carry native FICON traffi c
or Fibre Channel (SCSI) traffi c. LX and SX cannot be inter-
mixed on a single feature. The maximum number of FICON
Express2 features is 84, using three I/O cages.
FICON Express Channels
The z10 EC also supports carrying forward FICON Express
LX and SX channels from z9 EC and z990 (up to 120 chan-
nels) each channel operating at 1 or 2 Gb/sec auto-negoti-
ated. Each FICON Express feature has two independent
channels (ports).
