Learning Points – System z High Availability – Parallel Sysplex
1. Parallel Sysplex is a High Availability Solution implemented via
hardware, software, and microcode
2. A Coupling Facility (CF) provides Serialization and buffering
Services to members of a Parallel Sysplex – CFCC is the Operating
System for all CFs
3. Sysplex Timers (and/or FTP) assures synchronized clocks for all
members of a Parallel Sysplex – Required for Data Recovery
4. CF to Server connections can be ISC, ICB, PSIFB, or IC links – IC
links are virtual links when CF is LPAR on the same server
5. Parallel Sysplex protects end users from Planned or Unplanned
outages
6. WLM manages workloads across all members of a Parallel Sysplex
according to the customers “Business” priorities.
7. z/OS and Middleware may be level n, n-1, or n-2.

Learning Points - High Availability - GDPS
1. GDPS is a Continuous Availability (CA) and Disaster Recovery (DR)
Solution.
2. Recovery Time Objective (RTO) – Time to get all applications up and
running (after disaster).
3. Recovery Point Objective (RPO) – If data recovery backleveled the
data, how long? (what is the time currency of the data after recovery).
4. Metro Mirror is a Synchronous Disk replication technique limited to
distances less than 100K. (Example: GDPS/PPRC)
5. Global Mirror is an Asynchronous Disk replication technique across
unlimited distances. (Examples: DPS/Global Mirror and GDPS/XRC)
6. Hyperswap provides CA within a data center via GDPS/PPRC – this
protects from a Storage Control Failure with a RPO of 0 and an RTO of
less than 1 hr (typically far less).

Learning Points - z/OS and Workload Management
1. z/OS – IBM’s flagship Operating System
2. Current Release of z/OS – V1R10
3. z/OS release that requires z Architecture Server – V1R6 (and beyond)
4. z/OSe supports only z/800, z/890, and z9 BC. z/OSe does not support CICS, IMS,
or COBOL Development
5. zNALC now replaces z/OSe and is intended for New Workloads on System z and
significantly lowers the cost of z/OS – zNALC only effects the cost of z/OS
6. WLM is a standard subset of z/OS – no additional charge
7. WLM distributes resources among workloads according to customer business
priorities (Described within Policies set by the customer) across a Parallel Sysplex
8. IRD is a subset of PR/SM
9. IRD works with WLM to dynamically distribute Processor and I/O hardware
resources among LPARs running on the same physical server
10. IBM’s goal is to train 20,000 additional Mainframe professionals before 2010

Learning Points - System z Software Pricing

System z Monthly License Charges (MLC) pricing is typically used for DB2, CICS, IMS,
MQSeries, COBOL compilers, PL/1 compilers, Domino, z/OS, z/VSE.

z/OS.e disables or disallows certain products, applications, and workloads (such as IMS, CICS)
and supports z800/z890/z9 BC/z10 BC servers only.

zNALC replaces z/OSe and NALC for reduced z/OS pricing for qualified workloads across all
System z Servers..

Parallel Sysplex License Charges (PSLC) applies to qualified Parallel Sysplexes and
significantly lowers software prices by aggregating capacity across the entire qualified Parallel
Sysplex.

WLC Sub-Capacity Software pricing is determined by the processor capacity used during the
peak rolling four hour average for the LPAR(s) in which the software is running.
