Easy Tier 5 - Easy Tier Server Overview

� IBM Power p / DS8000 integration

� Easy Tier Server is an architecture:

– A Host flash-cache based on IBM research technology using IBM flash hardware (Easy Tier Caching Client)

– Easy Tier based algorithms for automatic application aware system-wide optimization (Easy Tier / Easy Tier Caching Server)

– A proprietary protocol provides in band (SAN) communication and coherency

� Hosts (Caching Clients)

– Work independently to cache their applications IO streams providing real-time performance enhancement

– Use the Cooperative Caching protocol to have cooperative system-aware caching that interfaces with IBM Storage running the Cooperative Caching Server

Easy Tier Cache Server

� While the Client Host SCSI stack driver does its own caching, it also receives ‘advice’ through Easy Tier Server specific communication

� The ‘advice’ is based on a unified view of the SAN storage, hosts, and their access patterns. It is a priority sorted list of extents

� The Client combines this advice with its own population list, resulting in both short and longer term cache population, higher hit ratio, and better storage solution optimization, including application aware storage.

� SAN based multi-host applications are enabled through the Easy Tier Server SAN Storage coherency protocol

� With coherency managed, storage advanced replication functions such as FlashCopy and remote mirroring are transparently enabled

Caching

Statistics

Easy Tier Cache Client

� The driver in the Host SCSI stack determines what to cache based on access patterns

� The cache makes per-io decisions of what to keep in cache and what to evict

� Selection algorithms achieve high performance by remembering the latest evicted tracks when selecting what to promote into the cache

System z and DS8870 Integration – New ICKDSF Function

� New ICKDSF parm – VerifyOffline

– INIT and REFORMAT commands will instruct the DS8870 to reject the I/O if the volume is

online to any other system

– Only the DS8870 has the information about every system (including different Sysplexes,

Vm, Linux,...) that has a path to this volume

� If the INIT/REFORMAT is rejected because it is online to some remote

system, client can issue Query Host Access from ICKDSF or DEVSERV

� Output listing indicates which host(s) have the volume online

29


New ICKDSF INIT/REFORMAT parameter with DS8870 R7.1

� Why does this matter?

� Issue 1 - Prevent accidental loss of data when initializing a volume with z/OS ICKDSF

– Even though it’s documented the volume must be offline to all other systems, mistakes can happen

• Prior to this enhancement, ICKDSF has no means to know if a volume is being used from other systems

• This function protects accidental destroying a volume that is online to other systems

– Example:

• Use ICKDSF to initialize a volume. Incorrect volume serial provided and specifies a volume that is online to another system

� Issue 2 - Volume Integrity– There are scenarios when an operation is performed to a volume and the volume is

required to be offline to all other systems, to protect the integrity of the volume

– Example:

• Volume restored using DSS full-volume restore on system A while it is also online to system B

• System B may not be aware of any changes that were made to the volume such as the Volume serial, VTOC location, Index location or changes to the VVDS (Catalog)

30


EC12 - New Channel Path Selection Algorithm with DS8870

� New channel path selection algorithm provides improved throughput and I/O service times when abnormal conditions occur:

– Abnormal conditions include the following:• Multi-system work load spikes

• Multi-system resource contention in the SAN or at the CU ports

• SAN congestion

• Destination port congestion

• Firmware failures in the SAN, channel extenders, WDMs, control units

• Hardware failures (link speeds did not initialize correctly)

• Miss-configuration

• Cabling Errors

• Dynamic changes in fabric routes (possible multi-hop cascading)

� When conditions occur that cause an imbalance in performance (I/O latency/throughput) across a set of channel paths to control unit

– Channel subsystem will bias the path selection away from poorer performing paths toward the well performing paths

• Accomplished by exploiting in-band I/O instrumentation and metrics of System z FICON and zHPF protocols and new intelligent algorithms in the channel subsystem to exploit this information

� Results show 50-100% throughput improvements with CU HBA/port congestion

– Complements DS8870 as premier storage consolidation platform

31


HyperSwap / DS8000 Synergy - z/OS Soft Fence

� After a GDPS/PPRC HyperSwap or an unplanned site switch, potential exposures exist to systems using the old Metro Mirror (MM) primaries

– Reading down-level data from the old MM primaries

– Updates the old MM primaries would be lost when the MM pairs are re-established in the reverse direction

� Example scenarios

– GDPS/PPRC provides IPL protection

• However, if GDPS isn’t used to IPL a system image, the IPL could be done against the former MM primaries

– Systems outside of the Sysplex will continue to access (and perhaps update) the old MM primary volumes following an unplanned HyperSwap

� Soft Fence (SF) will allow a host system to put a volume into a "soft fenced" state and also take it out of the “soft fenced” state. When a volume is in the soft fence state the disk subsystem will prevent all reads and writes to the volume from any host system


System z / DS8000 Integration - Timestamp Synchronization

� Future release of GDPS/Active-Active (A/A) is planned to integrate Global Mirror (GM) disk replication into the A/A environment

– Software replication will be mirroring the A/A workload data

– GM will be mirroring all data

• Both the A/A workload data and the non A/A workload data

� When a disaster occurs, A/A will need to understand the point of consistency for both software replication and GM in order to reconcile the two copies of the A/A workload data

– Consistency time stamps from software replication are relative to the Sysplex clock and the GM consistency time stamps are relative to the DS8870 clock

• The two clocks are not synchronized and time stamps cannot be validly compared to each other

� Solution is Host Timestamp is sent to the DS8000 for Read and Write I/O– GM Master Control Unit retrieves the Sysplex time from the I/Os issued from the

systems within the Sysplex and uses it when Consistency Groups are formed


VMware Support on the DS8870

DS8870 supports vStorage API for Array Integration (VAAI):– Integration with vStorage API’s to improve performance

• R7.0 provided� Full copy (aka XCOPY) primitive offloads work from production virtual servers to storage which improves

application performance and reduces host and SAN resource utilization� Hardware-assisted locking (via Atomic Test & Set) primitive enables a finer grained level of locking

(block-level instead of LUN-level) on VMFS metadata which is more efficient and also scales better in larger VMware clusters

• R7.1 provides� Write Same (zero blocks) primitive, the process of zeroing the VMDK is off-loaded to the storage

subsystem

– Example tasks that can benefit from improved performance :• VM creation/cloning/snapshots/deletion• vMotion and storage vMotion• Extending a VMFS Volume• Extending the size of a VMDK file

Therefore, no assurance can be given that an individual user will achieve throughput or performance improvements equivalent to the ratios stated here.
