Page 12: Z990 And Z900 Performance Comparison
As CMOS technology has been enhanced to support not only additional processing power, but also more engines, the entire server is modiﬁ ed to support the increase in processing power. The I/O subsystem supports a great amount of bandwidth through internal changes, thus providing for larger and quicker data movement into and out of the server.
Page 13: Z990 I/O Subsystem
• Comparing a 16-way z900 Model 216 to a z990 model with sixteen CPs enabled, it is estimated that the z990 model has 1.45 to 1.53 times the capacity of the 216. • Comparing a 16-way z900 Model 216 to a z990 model with thirty-two CPs enabled, and the workload execut- ing on the z990 executing in two 16-way LPARs, it is estimated that the z990 model has 2.4 to 2.9 times the...

Page 15: Z990 Channels And I/O Connectivity
LNX1 the initial install the ESCON features are installed in incre- ments of one. ESCON channels are available in four-port increments and are activated using IBM Licensed Internal Code, Conﬁ guration Control (LIC CC). LCSS1 Up to 120 FICON Express Channels The z990 supports up to 120 FICON Express channels.
Page 16 Internal Coupling Channel (IC) IC links emulate the coupling links between images within a single server. IC links are deﬁ ned in the IOCP. There is no physical channel involved. A z/OS image can connect to a coupling facility on the same server using IC capabilities.
Page 17: Fibre Channel Connectivity
The new increased number of FICON Express features available on the z990 helps distinguish this new server family, further setting it apart as enterprise class in terms of the number of simulta- neous I/O connections available for these FICON Express features.
Page 18 Many Fibre Channel directors provide dynamic connectiv- ity to native FICON control units. The IBM 2032 models 001, 064 and 140 (resell of the McDATA ED-5000, and Intrepid 6000 Series Directors) are 32-, 64- and 140-port high availability directors.

The raw bandwidth and distance capabilities that native FICON end-to-end connectivity has to offer makes them of interest for anyone with a need for high performance, large data transfers or enhanced multi-site solutions.

“hops” through a storage network for I/O connectivity. This support along with 2 Gbps link capability is being delivered together with IBM switch vendors IBM, CNT, and McDATA. FCP full fabric connectivity enables multiple FCP switches/ directors on a fabric to share links and there- fore provides improved utilization of inter-site connected resources and infrastructure.
Page 22 The new Open Systems Adapter-Express Integrated Con- sole Controller function (OSA-ICC), which is exclusive to IBM and the IBM z890 and z990 servers since it is based on the OSA-Express feature, supports the attachment of non-SNA 3270 terminals for operator console applications.
Page 23 The OSA-Express Gigabit Ethernet, 1000BASE-T Ethernet and Token-Ring features support QDIO (CHPID type OSD), which is unique to IBM. QDIO was ﬁ rst introduced to the world on the z900, in Communication Server for OS/390 2.7. Queued Direct Input/Output (QDIO), a highly efﬁ cient data...
Page 24 LAN and the ATM network or FDDI LAN. Server to User connections A key strength of OSA-Express and associated Commu- nications Server protocol support is the ability to accom- modate the customer’s attachment requirements, spanning combinations of TCP/IP and SNA applications and devices.
Page 25 LPAR Support of OSA-Express For z990 customers or customers who use the Processor Resource/Systems Manager (PR/SM) capabilities IBM offers the Multiple Image Facility (MIF), allowing the shar- ing of physical channels by any number of LPARs. Since a port on an OSA-Express feature operates as a channel, sharing of an OSA-Express port is done using MIF.
Page 26: Hipersockets
Furthermore, HiperSockets can be utilized by TCP/IP in place of XCF for sysplex connectivity between images which exist in the same server. Thus z/OS TCP/IP uses HiperSockets for connectivity between sysplex images in the same server and uses XCF for connectivity between images in different servers.

Cryptography In the on demand era security will be a strong requirement. The zSeries products will continue to address security with announcements and deliveries of products and features. The main focus in cryptography will continue to be very high and scalable performance for SSL algorithms, and secondly, to provide security-rich, symmetric performance for ﬁ...

Page 36 • ICB-2. The Integrated Cluster Bus-2 is used to provide high-speed coupling communication between a zSeries server or CF and a 9672 G5/G6 server or CF over short 1 GBps Peer Mode distances (~7 meters). For longer distances, ISC links must be used.
Page 37 4 x 2.0 GBps STIs I/O Cage Intelligent Resource Director Exclusive to IBM’s z/Architecture is Intelligent Resource Director (IRD), a function that optimizes processor and channel resource utilization across Logical Partitions (LPARs) based on workload priorities. IRD combines the strengths of the zSeries LPARs, Parallel Sysplex clustering, and z/OS Workload Manager.
Page 38 LPAR CPU Management LPAR CPU Management allows WLM working in goal mode to manage the processor weighting and logical processors across an LPAR cluster. CPU resources are automatically moved toward LPARs with the greatest need by adjusting the partition’s weight. WLM also manages the available processors by adjusting the number of logi- cal CPs in each LPAR.
Page 39 Parallel Sysplex clustering. A basic set of IBM services is designed to help address planning and early implementation requirements. These services can help you reduce the time and costs of planning a Parallel Sysplex environment and moving it into production.
Page 40 On the other hand, the GDPS solution based on Extended Remote Copy (XRC), referred to as GDPS/XRC, has the attributes of a Disaster Recovery solution. XRC is a com- bined hardware and software asynchronous remote copy solution. The application I/O is signaled completed when the data update to the primary storage is completed.
Page 41 unplanned HyperSwap capability lays the foundation for continuous availability, even in the event of a complete site failure. In the event of a complete failure of the site where the primary disk resides, the systems in the site with the secondary disks can continue to remain active even though workload running on these systems needs to be restarted.
Page 42 February 2004. GDPS/PPRC and Cross-site Parallel Sysplex distance extended to up to 100 km: On October 31, 2003, IBM deliv- ered, via a Request for Price Quote (RPQ), the capability to conﬁ gure GDPS/PPRC or a multi-site Parallel Sysplex up to a distance of up to 100 kilometers (62 miles) between two sites.
