z10 EC Channels and I/O Connectivity

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
		Feature
FICON Express4 10KM LX	3321	Single mode fiber	4
FICON Express4 4KM LX	3324	Single mode fiber	4
FICON Express4 SX	3322	Multimode fiber	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

fiber 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).
