22 z/os and DS8000 zhpf Performance Advantages zhpf Performance Exclusive - Significant Throughput gains in many areas Reduced batch window for I/O intensive batch DS8000 I/O commands optimize QSAM, BPAM, and BSAM access methods for exploiting zhpf Up to 30% improved I/O service times Complete conversion of DB2 I/O to zhpf maximizes resource utilization and performance Up to 52% more Format write throughput (4K pages) Up to 100% more Pre-formatting throughput Up to 19% more Sequential pre-fetch throughput Up to 23% more dynamic pre-fetch throughput (40% with Flash/SSD) Up to 111% more Disorganized index scans yield throughput (more with 8K pages) DB2 10 and zhpf is up to 11x faster over DB2 V9 w/o HPF Up to 30% reduction in Synchronous I/O cache hit response time Improvements in cache handling decrease response times 3x to 4x% improvement in Skip sequential index-to-data access cache miss processing Up to 50% reduction in the number of I/O operations for query and utility functions DS8000 algorithm optimizes DB2 List-Prefetch I/O Reduced transaction response time Reduced batch window Better customer experience 21 21

23 DFSORT zhpf Exploitation in z/os2.2 DFSORT zhpf Exploitation DFSORT normally uses EXCP for processing of basic and large format sequential input and output data sets (SORTIN, SORTOUT, OUTFIL) DFSORT already uses BSAM for extended format sequential input and output data sets (SORTIN, SORTOUT and OUTFIL). BSAM already supports zhpf New enhancement: Update DFSORT to prefer BSAM for SORTIN/SORTOUT/OUTFIL when zhpf is available DFSORT will automatically take advantage of zhpf if it is available on your system; no user actions are necessary. Why it Matters: Taking advantage of the higher start rates and bandwidth available with zhpf is expected to provide significant performance benefits on systems where zhpf is available. 22

24 DS8000 Advanced Caching Algorithms Classical (simple cache algorithms): LRU (Least Recently Used) / LRW (Least Recently Written) Cache innovations in DS8000: 2004 ARC / S-ARC dynamically partitions the read cache between random and sequential portions 2007 AMP manages the sequential read cache and decides what, when, and how much to prefetch 2009 IWC (or WOW: Wise Ordering for Writes) manages the write cache and decides what order and rate to destage 2011 ALP enables prefetch of a list of non-sequential tracks providing improved performance for DB2 workloads 24

27 Why Flash on the mainframe? Very good overall z/os average response times can hide many specific applications which can gain significant performance benefits from the reduced latency of Flash Larger zsystems memory sizes and newer Analytics and Cognitive workloads are resulting in more cache unfriendly IO patterns which will benefit more from Flash Predictable performance is also about handling peak workloads and recovering from abnormal conditions. Flash can provide an ability to burst significantly beyond normal average workloads For clients with a focus on cost, Hybrid Systems with Flash and 10K Enterprise drives are higher performance, greater density and lower cost than 15K Enterprise drives 27

28 I/O Priority Manager and Work Load Manager Application A and B initiate an I/O operation to the same DS8880 rank (may be different logical volumes) zwlm sets the I/O importance value according to the application priority as defined by system administrator If resources are constrained within the DS8880 (very high utilization on the disk rank), I/O Priority Manager will handle the highest priority I/O request first and may throttle low priority I/Os to guarantee a certain service level 28

29 zos Global Mirror (XRC) / DS8880 Integration - Workload Manager Based Write Pacing Software Defined Storage enhancement to allow z Systems Workload Manager (WLM) to control XRC Write Pacing Client benefits Reduces administrative overhead on hand managing XRC write pacing Reduces the need to define XRC write pacing on a per volume level allowing greater flexibility in configurations Prevents low priority work from interfering with the Recovery Point Objective of critical applications Enables consolidation of workloads onto larger capacity volumes P SDM WLM S 29

30 SAP/DB2 Transactional Latency on z/os How do we make transactions run faster on z Systems and z/os? A banking workload running on z/os: DB2 Server time: 5% Lock/Latch + Page Latch: 2-4% Sync I/O: 60-65% Dispatcher Latency: 20-25% TCP/IP: 4-6% This is the write to the DB2 Log 1. Faster CPU 2. Software scaling, reducing contention, faster I/O 3. Faster I/O technologies such as zhpf, 16 Gbs, zhyperwrite, zhpf ED II, etc 4. Run at lower utilizations, address Dispatcher Queueing Delays 5. RoCE Express with SMC-R Lowering the DB2 Log Write Latency will accelerate transaction execution and reduce lock hold times 30

31 HyperSwap / DB2 / DS8880 Integration zhyperwrite DB2 performs dual, parallel Log writes with DS8880 Metro Mirror Avoids latency overhead of storage based synchronous mirroring Improved Log throughput Reduced DB2 log write response time up to 43 percent Primary / Secondary HyperSwap enabled DB2 informs DFSMS to perform a dual log write and not use DS8880 Metro Mirroring if a full duplex Metro Mirror relationship exists Fully validated with GDPS and TPC-R Client benefits Reduction in DB2 Log latency with parallel Log writes HyperSwap remains enabled 31

One APAR reported since GA 4Q

34 R8.1 - SuperPAV Building upon IBM s success with PAVs and HyperPAV, SuperPAVs which provide cross control unit aliases Previously aliases must be from within the logical control unit (LCU) 3390 devices + aliases 256 could be a limiting factor LCUs with many EAVs could potential require additional aliases LCUs with many logical devices and few aliases required reconfiguration if they required additional aliases SuperPAVs, an IBM DS8880 exclusive, extends aliases beyond the LCU barrier SuperPAVs can cross control unit boundaries and enable aliases to be shared among multiple LCUs provided that: The 3390 devices and the aliases are assigned to the same DS8000 server (even/odd LCU) The devices share a common path group on the z/os system Even numbered control units with the exact same paths (CHPIDs [and destination addresses]) are considered peer control units and may share aliases Odd numbered control units with the exact same paths (CHPIDs [and destination addresses]) are considered peer control units and may share aliases There is still a requirement to have a least one base device per LCU so it is not possible to define a LCU with nothing but aliases. Using SuperPAVs will provide benefits to clients especially with a large number of systems (LPARs) or many LCUs sharing a path group 35

35 R8.1 - DB2 Castout Accelerator In DB2, the process of writing pages from the group buffer pool to disk as referred to as castout DB2 uses a defined process to move buffer pool pages from group buffer pool to private buffer pools to disk When this process occurs, DB2 writes long chains of writes which typically contain multiple locate record domains. Each I/O in the chain will be synchronized individually Reduces overheads for chains of scattered writes This process is not required for DB2 usage DB2 requires that the updates are written in order What is changing? Media Manager has been enhanced to signal to the DS8000 that there is a single logical locate record domain even though there are multiple imbedded locate records The data hardening requirement for the entire I/O chain are as if this was a single locate record domain This change is only done for zhpf I/O Significant benefit also when using Metro Mirror in this environment Prototype code results showed a 33% reduction in response time when replicating with Metro Mirror for typical write chain for DB2 castout processing and 43% when Metro Mirror is not in use.

42 IBM z Systems / DS8880 exclusive I/O enhancements Reduce transactional latency, improve performance over distance, and increase scalability Forward Error Correction Code (FEC) Allows FICON channels to operate at higher speeds, over longer distances, with reduced power and higher throughout while retaining traditional RAS levels Used for controlling errors in data transmission over unreliable or noisy communication channels Sender encodes messages in a redundant way by using error-correcting code (ECC) Allows the receiver to detect a limited number of errors that might occur anywhere in the message and often corrects these errors without retransmission Performance RAS FICON Dynamic Routing (FIDR) Enables exploitation of SAN dynamic routing polices in the fabric to lower cost and improve performance for supporting I/O devices Share ISLs for FICON traffic and FCP Metro Mirror traffic Better utilization of available ISL bandwidth Simplified Management of ISLs Performance 47

69 z Systems / DS8880 Integration Capabilities Ease of Mgmt Ease of Use Simplified, easy to use GUI that is common across the IBM Storage portfolio Enhanced functionality includes: System health status reporting Monitoring and alerting Streamlined logical configuration Provide simplified creation, assignment and management of volumes Simpler performance management with Easy Tier and the wide striping of data across physical storage within Storage Pools ICKDSF Verify Offline and Query Host Access prevent accidental initialization of a volume and informs operations which systems have a volume online Thin Provisioning - Extent Space Efficient (ESE) support and Small Extents for CKD GDPS DB2, IMS, CICS DFSMShsm, DFSMSdss DFSMSdfp: Device Services, Media Manager, SDM z/os (IOS, etc.), z/vm, Linux for z Systems z Systems Hardware DS

70 Thin Provisioning for CKD Volumes CKD volumes can now be defined as thin provisioned ESE volumes Small extents are the same size as EAV extents (21 cylinders) Same performance as Standard volumes More efficient use of capacity free capacity is available to all volumes Simplify configuration by standardizing device sizes Allows for sharing of spare capacity across sysplexes Faster volume replication - unallocated extents do not have to be copied Space release at a volume level is supported ICKDSF can also be used to release space when an ESE volume is initialized The initckdvol DSCLI command can be used to free space initckdvol dev storage_image_id -action releasespace -quiet volume_id Extent level space release will require future z/os support 90

71 Thin Provisioning Concept in DS8000 Thin provisioned volume is referred to as Extent Space Efficient (ESE) volume With the first write operation to the volume, real capacity from the extent pool will be allocated to the volume Real Capacity is just the sum of all extents available in extent pools Virtual Capacity is the sum of all defined host volumes capacity (and can be much larger than the real capacity Ratio between virtual and real capacity represents the storage over-provisioning Thin provisioning makes it easier to manage and also monitor system capacity 91

72 Thin Provisioning Planning Considerations Usage If you plan on using thin provisioning, do it with small extents If you want to go with fully provisioned volumes and do not plan to use thinprovisioned volumes use extent pools with large extents Thin provisioning is an attribute that you specify when creating a volume. Licensing Thin-provisioned volume support is contained in the Base Function license group 92
