IBM z/OS - Manual

7 The new IBM ^ zSeries Application Assist Processor (zAAP), planned to be available on the IBM ^ zSeries 990 (z990) and zSeries 890 (z890) serv- ers, is an attractively priced specialized processing unit that provides strategic z/OS Java execution environment for customers who desire the powerful i...

8 To support the new scalability of the z990 a new improve- ment to the I/O Subsystem has been introduced to “break the barrier” of 256 channels per Central Electronic Com- plex (CEC). This provides “horizontal” growth by allowing the defi nition of up to four Logical Channel SubSystems each capable...

10 The z990 offers 4 models, the A08, B16, C24 and D32, which can be confi gured to give customers a highly scal- able solution to meet the needs of both high transaction processing applications and the demands of e-business. The new model structure provides between 1-32 confi gu- rable Processor Un...

11 Although CBU and On/Off Capacity on Demand can both reside on the server, the activation of On/Off Capacity on Demand is mutually exclusive with Capacity BackUp (CBU) and no physical hardware upgrade will be sup- ported while On/Off Capacity on Demand is active. This important new function for zS...

13 • 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 ...

14 z990 Logical Channel SubSystems (LCSSs) and support for greater than 15 Logical Partitions (LP) In order to provide the increased channel connectivity required to support the scalability of the z990, the z990 channel I/O SubSystem delivers a breakthrough in con- nectivity, by providing up to 4 LC...

15 Logical Channel SubSystem (LCSS) Spanning The concept of spanning channels provides the ability for a channel to be confi gured to multiple LCSSs and therefore they may be transparently shared by any/all of the logical partitions in those LCSSs. Normal Multiple Image Facility (MIF) sharing of a c...

17 Fibre Channel Connectivity The on demand operating environment requires fast data access, continuous data availability, and improved fl ex- ibility all with lower cost of ownership. The new increased number of FICON Express features available on the z990 helps distinguish this new server family, ...

21 FCP Full fabric connectivity FCP full fabric support means that any number of (single vendor) FCP directors/ switches can be placed between the server and FCP/ SCSI device, thereby allowing many “hops” through a storage network for I/O connectivity. This support along with 2 Gbps link capability ...

22 z990 OSA-Express 1000BASE-T Ethernet The new OSA-Express 1000BASE-T Ethernet feature replaces the current Fast Ethernet (10/100 Mbps) feature. This new feature is capable of operating at 10,100 or 1000 Mbps (1 Gbps) using the same copper cabling infrastructure as Fast Ethernet making transition t...

23 Queued Direct Input/Output (QDIO) 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 ...

26 HiperSockets, a function unique to the zSeries, provides a “TCP/IP network in the server” that allows high-speed any-to-any connectivity among virtual servers (TCP/IP images) and LPARs within a zSeries system without any physical cabling. HiperSockets decreases network latency and increases bandw...

27 This support gives the user the fl exibility to optimize and tune each HiperSockets to the predominant traffi c profi le, for example to distinguish between “high bandwidth” workloads such as FTP versus lower bandwidth interactive workloads. The HiperSockets function provides many possibilities f...

28 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...

30 The z990 supports concurrent memory upgrade. This capa- bility will allow a processor’s memory to be increased with- out disrupting the processor operation. To take advantage of this capability, a customer should not plan processor storage on the 16 or 32 GB increments. A customer with a Model A0...

The Integrated Cluster Bus-3 is used to provide high-speed coupling communication between a z990 server or CF and a z800/z900 server or CF or between two z800/z900s over short distances (~7 meters). For longer distances, ISC-3 links must be used. The z990 features the STI-3 card which re...
