Cryptographic Support for Linux

Linux on zSeries running on standard z990, z900, and

z800 engines is capable of exploiting the hardware cryp-

tographic feature provided by the PCICA feature (PCI

Cryptographic Accelerator). This enables customers

implementing e-business applications on Linux on zSeries

to utilize this enhanced hardware security.

1) A minimum of one I/O feature (ESCON, FICON Express) or one Coupling

Link (ICB, ISC-3) is required.

2) Maximum of 48 ESCON features/720 active channels on Model A08.

Maximum of 48 FICON features/96 channels on A08.

3) Each ESCON feature has 16 channels of which 15 channels may be acti-

vated. One channel is always reserved as a spare.

4) ESCON channels are purchased in increments of four and are activated

via Licensed Internal Code, Conﬁ guration Control (LIC CC). Channels

are activated equally across all installed 16-port ESCON features for

high availability.

5) The maximum quantity of FICON Express, OSA-Express, PCICA, and

PCIXCC in combination cannot exceed 20 features per I/O cage and 60

features per server.

6) The STI distribution cards, which support ICB-2 and ICB-3, reside in the

I/O cage. Each STI distribution card occupies one I/O slot.

7) The maximum number of Coupling Links combined (ICs, ICB-2s, ICB-3s,

ICB-4s, and active ISC-3 links) cannot exceed 64 per server.

8) ICB-4s do not require connectivity to a card in the I/O cage. ICB-4s are

not included in the maximum feature count for I/O slots.

9) A maximum of 32 ISC-3s can be deﬁ ned in Compatibility ode (operating

at 1 Gbps, instead of 2 Gbps).

10) It is recommended that an initial order for ISC-3 include two links. When

two links are purchased, two ISC-3 features are shipped and activated

links are balanced across ISC-3 features for high availability.

11) The total number of PCICAs and PCIXCCs cannot exceed eight fea-

tures per server.

12) The total number of PCICAs cannot exceed two features per I/O cage.

13) PCIXCC feature increments are 0, 2, 3, or 4.
