zSeries 990 Family Conﬁguration Detail

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, Conﬁguration 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.
