Additionally , several service enhancements have also been designed to avoid unscheduled outages and include continued focus on fi rmware quality , r educed chip count on Single Chip Module (SCM) and memory subsystem improvements.
The System z10 BC is designed to provide balanced system perfor mance. From pr ocessor storage to the system’ s I/O and network channels, end-to-end bandwidth is provided and designed to deliver data wher e and when it is needed.
Timed Interconnect Multiplexer (STI-MP) car d. There ar e two types of HCA fanout cards: HCA2-C is copper and is always used to connect to I/O (IFB-MP card) and the HCA2-O which is optical and used for customer Infi niBand coupling. The z10 BC has been designed to offer high performance and effi cient I/O structure.
z10 BC model upgrades The z10 BC provides for the dynamic and fl exible capac- ity growth for mainframe servers. Ther e are full upgrades within the z10 BC and upgrades from any z9 BC or z890 to any z10 BC. T emporary capacity upgrades are available through On/Of f Capacity on Demand (CoD).
z10 BC P erf ormance The perfor mance design of the z/Architectur e can enable the server to support a new standard of perfor mance for applications through expanding upon a balanced system approach.
A new host bus interface using Infi niBand with a link data rate of 6 GBps, was introduced on the z10 BC. It pr ovides enough throughput to support the full capacity and pro- cessing power of the CPC. The z10 BC contains an I/O subsystem infrastructure which uses up to four I/O drawers that provides eight I/O slots in each drawer .
ESCON Channels The z10 BC supports up to 480 ESCON channels. The high density ESCON feature has 16 ports, 15 of which can be activated for customer use. One port is always reserved as a spar e which is activated in the event of a failure of one of the other ports.
FICON Express Channels The z10 BC also supports carr ying forward FICON Express LX and SX channels fr om z9 BC and z990 each channel operating at 1 or 2 Gb/sec auto-negotiated.
The FICON Express4, FICON Expr ess2 and FICON Express channels support native FICON and FICON Channel-to-Channel (CTC) traffi c for attachment to servers, disks, tapes, and printers that comply with the FICON architectur e. Native FICON is supported by all of the z10 BC operating systems.
FCP – increased performance for small block sizes The Fibre Channel Pr otocol (FCP) Licensed Internal Code has been modifi ed to help pr ovide increased I/O operations per second for small block sizes.
IBM System Storage DS8000 Release 4.1 delivers new capabilities to support High Per formance FICON for System z, which can improve FICON I/O thr oughput on a DS8000 port by up to 100%. The DS8000 series Licensed Machine Code (LMC) level 5.4.2xx.xx (bundle version 64.
Extended distance FICON – improved performance at extended distance An enhancement to the industry standard FICON architec- ture (FC-SB-3) helps avoid degradation of performance at extended distances by implementing a new protocol for “persistent” Information Unit (IU) pacing.
FICON Link Incident Reporting FICON Link Incident Reporting is designed to allow an operating system image (without operating intervention) to register for link incident r eports, which can improve the ability to capture data for link err or analysis.
The OSA-Express3 featur es are exclusive to System z10. There ar e operating system dependencies for exploitation of two ports in OSD mode per PCI-E adapter . Whether it is a 2-port or a 4-por t feature, only one of the ports will be visible on a PCI-E adapter if operating system exploitation updates are not installed.
The OSA-Express3 and OSA-Expr ess2 Ethernet features support the following CHPID types: CHPID OSA-Express3, Purpose/T raffi c T ype OSA-Express2 Features OSC 1000BASE-T OSA-Integrated Console Control.
OSA-Express3-2P Gigabit Ethernet SX The OSA-Express3-2P Gigabit Ethernet (GbE) short wavelength (SX) feature has two ports which reside on a single PCIe adapter and share one channel path identifi er (CHPID). Each port suppor ts attachment to a one Gigabit per second (Gbps) Ethernet Local Area Network (LAN).
When confi gured at 1 Gbps, the 1000BASE-T Ethernet feature operates in full duplex mode only and supports jumbo frames when in QDIO mode (CHPID type OSD). OSA-Express QDIO data connection isolation for the z/VM environment Multi-tier security zones are fast becoming the network confi guration standard for new workloads.
OSA-Express Network T raffi c Analyzer is exclusive to the z10 BC, z9 BC, z10 EC, and z9 EC, and is applicable to the OSA-Express3 and OSA-Expr ess2 features when confi gured as CHPID type OSD (QDIO), and is supported by z/OS.
Layer 2 transport mode: When would it be used? If you have an environment with an abundance of Linux images in a guest LAN environment, or you need to defi ne router guests to pr ovide the connection between these guest LANs and the OSA-Express3 featur es, then using the Layer 2 transport mode may be the solution.
Direct Memory Access (DMA) OSA-Express3 and the operating systems shar e a common storage area for memory-to-memory communi- cation, reducing system overhead and impr oving perfor - mance. There ar e no read or write channel pr ograms for data exchange.
T oken-Ring networks and ESCON channels with an Ether - net network and integrated LAN adapters on System z10, OSA-Express3 or OSA-Expr ess2 GbE or 1000BASE-T . OSA-Express for NCP is supported in the z/OS, z/VM, z/VSE, TPF , z/TPF , and Linux on System z environments.
The HiperSockets function, also known as internal Queued Direct Input/Output (iDQIO) or internal QDIO, is an inte- grated function of the z10 BC server that provides users with attachments to up to sixteen high-speed “virtual” Local Area Networks (LANs) with minimal system and network overhead.
interrupt. This enhancement is transparent to the operating system in the receiving LP AR. HiperSockets Multiple Write Facility , with fewer I/O interrupts, is designed to reduce CPU utilization of the sending and receiving LP AR. The HiperSockets Multiple Write solution moves multiple output data buffers in one write operation.
T oday’ s world mandates that your systems are secur e and available 24/7. The z10 BC employs some of the most advanced security technologies in the industry—helping you to meet rigid regulatory requir ements that include encryption solutions, access control management, and extensive auditing features.
Enhancements to CP Assist for Cryptographic Func- tion (CP A CF): CP ACF has been enhanced to include support of the fol- lowing on CPs and IFLs: • Advanced Encryption Standard (AES) for 192-bit key.
Impro ved key e xchange – Added Improved key exchange with non-CCA cryptographic systems. New fea- tures added to IBM Common Cryptographic Architectur e (CCA) are designed to enhance the ability to .
Support for AES encr yption algorithm includes the master key management functions requir ed to load or generate AES master keys, update those keys, and re-encipher key tokens under a new master key .
TKE additional smart cards – new f eature Y ou have the capability to order Java-based blank smart cards which of fers a highly effi cient cryptographic and data management application built-in to read-only memory for storage of keys, certifi cates, passwords, applications, and data.
It may sound revolutionary , but it’ s really quite simple. In the highly unpredictable world of On Demand business, you should get what you need, when you need it. And you should pay for only what you use. Radical? Not to IBM. It’ s the basic principle underlying IBM capacity on demand for the IBM System z10.
can be added up to what the physical hardwar e model can contain for up to 10 days for a test activation or 90 days for a true disaster recovery . On system z10 the CBU entitlement recor ds contain an expiration date that is established at the time of order and is dependent upon the quantity of CBU years.
• The quantity of temporary CP capacity ordered is limited by the quantity of purchased CP capacity (permanently active plus unassigned) • The quantity of temporary IFLs ordered is limited by quan.
z/OS Capacity provisioning allows you to set up rules defi ning the circumstances under which additional capac- ity should be provisioned in or der to fulfi ll a specifi c busi- ness need. The rules are based on criteria, such as: a specifi c application, the maximum additional capacity that should be activated, time and workload conditions.
In today’ s on demand environment, downtime is not only unwelcome—it’ s costly . If your applications aren’t consis- tently available, your business suffers. The damage can extend well beyond the fi nancial r ealm into key areas of customer loyalty , market competitiveness and regulatory compliance.
With the z10 BC, signifi cant steps have been taken in the area of server availability with a focus on r educing pre- planning requir ements. Pre-planning r equirements ar e minimized by delivering and reserving 8 GB for HSA so the maximum confi guration capabilities can be exploited.
Dynamic Oscillator Switchover The z10 BC has two oscillator cards, a primary and a backup. For most cases, should a failure occur on the pri- mary oscillator card, the backup can detect it, switch over , and provide the clock signal to the system transpar ently , with no system outage.
Power and cooling discussions have entered the budget planning of every IT environment. As energy prices have risen and utilities have restricted the amount of power usage, it is important to review the role of the server in bal- ancing IT spending.
IBM System z servers stand alone against competition and have stood the test of time with our business resiliency solutions. Our coupling solutions with Parallel Sysplex technology allow for greater scalability and availability .
16 allows one of these protocol exchanges to complete asynchronously . This allows faster duplexed request ser - vice time, with more benefi ts when the Coupling Facilities are further apart, such as in a multi-site Parallel Sysplex environment.
Parallel Sysplex Coupling Connectivity The Coupling Facilities communicate with z/OS images in the Parallel Sysplex environment over specialized high- speed links. As processor performance increases, it is important to also use faster links so that link per formance does not become constrained.
The IBM System z10 BC also takes advantage of Infi niBand as a higher -bandwidth replacement for the Self- Timed Interconnect (STI) I/O interface features found in prior System z servers.

join the two server CTN. Previously , if both the Preferr ed Time Server (PTS) and the Backup Time Server (BTS) experienced a simultaneous power outage (site failure), or both experienced a POR, reinitialization of time, and special roles (PTS, BTS, and CTS) was r equired.
Continuous A vailability of NTP servers used as Exter- nal Time Source : Improved External Time Source (ETS) availability can now be provided if you confi gure dif ferent NTP servers for the Preferr ed Time Server (PTS) and the Backup Time Server (BTS).
Application Programming Interface (API) to automate STP CTN reconfi guration : The concept of “a pair and a spare” has been ar ound since the original Sysplex Couple Data Sets (CDSs). If the primary CDS becomes unavailable, the backup CDS would take over .
The new functions available on the Hardwar e Management Console (HMC) version 2.10.1 as described apply exclu- sively to System z10. However , the HMC version 2.10.1 will continue to support the systems as shown. The 2.10.1 HMC will continue to support up to two 10/100 Mbps Ethernet LANs.
There is now a new Console Manager task that of fers basic messaging capabilities to allow system operators or administrators to coordinate their activities.
