    Change in I/O structure :

    New IO Towers are directly connected to the servers via point-to-point PCI-e cables. IO Towers no longer share common loops, they connect directly to each server

    via separate cables and link cards.

    DS8700 IO Fabric

    Key difference: The RIO loop in DS8700 will be isolated Unlike DS8000, DS8700 IO towers will be on a separate point-to-point

    connection This isolates the server communication from IO fabric failures, power supply

    problems, and repair procedures.

    DS8700 will use a PCI-e IO Fabric instead of PCI-x. PCI Express reduces the impact of hardware failures

    DS8000 SARC Cache Algorithm

    SARC : Sequential Prefetching in Adaptive Replacement Cache

    Best caching algorithms in industry

    Simplified Adaptive Replacement Cache (SARC) Self-Learning algorithms Adaptively and dynamically learn what data should be

    stored in Cache based upon the recent access and frequency needs of the Hosts

    Adaptive Replacement Cache Most advanced and sophisticated algorithms to

    determine what data in Cache is removed to accommodate newer data

    Pre-fetching Predictive algorithm to anticipate data prior to a host

    request and loads it into Cache

    Benefits Leading performance Been proven to improve Cache hit by up to 100% over

    previous IBM caching algorithms and improve I/O response time by 25%

    More efficient use of Cache Intelligent caching algorithm profiles Host access

    patterns to determine what data is stored Need less Cache than competitors

    DS8000 Cache Efficiency elements

    Example : Two random 4KB blocks

    blk1

    blk2

    DS8000

    4KB slots

    blk2

    blk1HDS high-end

    16KB slots

    --wasted--

    blk1EMC DMX-3/4

    64KB slotsblk2

    -----------------------------wasted-----------------------------

    The more random the I/Os and the smaller the blocks,

    the more cache that is wasted due to large cache slot sizes

    DS8000 Utilizes Less Resources to Manage Cache

    System cache is a key factor in application I/O

    performance.

    It is also relatively expensive and relatively small

    compared to total drive capacity.

    Optimizing cache use via efficient system

    management allows the system to do more with

    less.

    DS8000 logical configuration and virtualisation

    6+P+S 146GB 6+P+S 146GB

    An array site is a collection of 8 drives of the same type spread across both internal fabrics(loops) on the DS8000

    An array is formed when the drives in an array site are formed into a RAID group (RAID5/6/10) and potentially a spare is assigned

    A rank is created when an array is formatted for either CKD or FB

    Ranks are divided into extents which are either 1GB (FB) or 1113 cylinders (CKD)

    An extent pool is a collection of ranks all of which are managed by the same DS8000 server (0/1)

    Volumes are created from one or more extents from a single extent pool

    A LSS/LCU is a collection of volumes and has relevance mostly for copy services and CKD

  • 2011 IBM Corporation

    Journe Technologique STG IBM Bois Colombes, 13 Janvier 2011

    Volume allocation algorithms

    The rotate volumes allocation algorithm will attempt to keep a volume on a single rank and will rotate the rank for each allocated volume among the ranks in the extent pool

    The rotate extents allocation algorithm will spread a volume over all available ranks in the extent pool and will rotate the rank for each extent among the ranks in the extent pool. The starting rank for each allocated volume will also be rotated in a similar manner

    Note : There is also a historical allocation method called legacy which may be present on very old DS8000s and involved allocating the volume on the rank with the most available space

    Rotate extents is also referred to as Storage Pool Striping and is the recommended method for multiple rank extent pools

    Value proposition:

    Increasing DS8000s superior resiliency to support todays lower-cost, less-

    reliable, large-capacity drives

    RAID 6 - offers protection from double disk failures by using a second independent distributed parity scheme (dual parity)

    Can tolerate loss of data in two strips of any stride without data loss 2 Disk Failures 1 Disk Failure + 1 Media Error 2 Media Errors

    Critical for larger drives (SATA/FATA), which have longer rebuild times and thus longer periods of potential exposure should two drives start failing

    SSDs compared to spinning disks

    Disadvantages

    Wear issues Errors may creep in over time SSD controller designed in multiple

    layers of error recovery (ECC, RAID, write-reduction, wear-leveling technology)

    Capacity Relatively small capacity per drive unit

    today compared to spinning disks NAND and SSD industry expecting

    breakthrough in capacity (SLC, MLC, XLC and PCM technology.)

    Cost Significant more raw cost/GB today than

    HDD Need new technology to improve cost

    performance ratio.

    Advantages

    Absence of mechanical moving parts Significantly more reliable

    Green Power - Fraction of power consumed Heat - Fraction of heat dissipated

    and tolerant of wider range of temperature.

    Performance Up to 100x more throughput and 10x

    lower response time than 15K RPM spinning disks

    $/IOPS is significant better than traditional spinning disk.

    Result:

    Improve application response time of 60-70+% at peak load by moving 5% of hot spot to SSD.

    Demonstration of ADR:

    Compare SPC-1 likeworkload on HDD versus ADR with HDD and SSD

    ADR Technology identifies and non-disruptively migrates hot data from HDD to SSD. About 4% of data is migrated from HDD to SSD.

    All volumes appear to be logicallyhomogenous to apps. But data is placed at the right tier of storage based on its usage through smart data placement and migration.

    Easy Tier is a new DS8700 feature that supports online dynamic relocation of data Workload learning algorithms collect I/O statistics and generate a heat map of data

    to be optimized on SSD Data can be relocated to/from SSD and FC/SATA

    Automatic Mode

    Provides automated extent level relocation granularity

    Requires use of a merged extent pool Manual Mode

    Provides online dynamic volume relocation capability

    Ignores workload activity in plan generation statistics while disabled Plan generation suppressed if insufficient monitoring history since last plan (16 hours) Managed volumes is normal setting and monitors workload on volumes in managed

    pools if the Easy Tier LIC feature is enabled All volumes causes all logical volumes to be monitored (with or without LIC feature)

    Can be used with analysis tools prior to ordering and enabling the LIC featureCan be used to analyze logical volumes in homogeneous extent pools as

    candidates for mixed technology pool

    Analysis Tools Can offload reports on extent monitoring and obtain SSD capacity planning

    recommendations Can engage IBM for extended analysis and consulting

    Easy Tier Manual Mode allows a user to perform the following actions: Volume Migration

    User can change a logical volumes storage technology by dynamically relocating between extent pools

    User can change a logical volumes extent allocation algorithm (EAM) (e.g. can re-rotate extents within the target extent pool)

    Extent Pool Merge User can merge two existing extent pools without moving data

    Consolidate extent pools with equivalent disks

    Merge extent pools with to create a mixed technology extent pool for Automatic Mode
