Real-time Compression: Capability

Real-time Compression (RtC) is supported only on the model V5030

– The optional 16GB memory upgrade on each node canister is required

– When the first compressed volume is created 4 of the 6 CPU cores are allocated to RtC

• Of the 32GB of memory on each node canister roughly 9-10GB is allocated to RtC

ModelCompression Disabled Compression Enabled

NormalProcessing

RtC NormalProcessing

RtC

V5010 2 cores NA NA NA


– There are no hardware compression accelerators as in the V7000 Gen2

• The actual LZ4 compression is done by the CPUs as was the case with the V7000 Gen1

– The faster CPU with more cores, the extra memory and the Hyper-threading capability of theV5030 as well as improvements to RtC software results in good performance for smallercustomer configurations common to the market segment this product is intended to serve

The working set is the size of the compressed volumes that we are randomly accessing. For 640GiB set we used 32 – 20GiB compressed volumes, for 1.2TiBset we used 64 – 20GiB compressed volumes and for 2.4TiB set we used 128 – 20GiB compressed volumes. As the working set increases with the V5030, theworst case numbers drop off significantly compared to the V7000 Gen2. This is primarily due to less memory available for RtC on the V5030 compared to theV7000 Gen2 and more work overall is performed by the 4 RtC dedicated cores in lieu of no acceleration cards as in in the V7000 Gen2. However, compared toGen1 V7000 the numbers are very good and the V5030 is a strong performer in the target market segment.

Note that the definition of worst case is 100% random I/O andlower end of compressibility thus little boost from temporal locality.

Storwize V5000 Gen2: Initial Configuration

All three models use a technician port to perform initial setup just as done with SVC/V7000

However the implementation of the technician port varies between models:– On V5010/20 the second 1GbE port (labelled T) is initially enabled as a technician port

– After cluster creation this port is disabled and can then be used for I/O and/or management

– On V5030 the implementation is identical to SVC/V7000– The onboard 1GbE port (labelled T) is permanently enabled as a technician port

– Connecting the technician port to the LAN will disable the port

The V5010/20 technician port can be re-enabled after initial setup– satask chserviceip -techport enable -force


– satask chserviceip -techport enable -force

– satask chserviceip -techport disable

33

Storwize V5000 Gen2: Miscellaneous

The 4-port 16Gb FC adapter available for the Storwize V5000 Gen2 models supportsattachment to 16/8Gb ports on Brocade but only 16Gb FC ports on Cisco

– http://www-01.ibm.com/support/docview.wss?uid=ssg1S1005423

– Submit a SCORE as needed for Cisco 8Gb FC support

The Storwize V5000 Gen2 models are not currently Energy Star Certified

– The process to get certified requires the systems be GA and they won't be until March 4th

– Testing/certification is lengthy, but we are expecting all models will qualify later this year


Cannot use existing Storwize V3700, V5000 Gen1, V7000 Gen1/Gen2 drives orexpansion enclosures with any of the V5000 Gen2 models

If solution will be virtualizing external storage systems and plan is to compress andencrypt data as it is sent to external MDisks, we’d recommend clustering two systemsto lend more processing capability to these more CPU intensive requirements

Storwize V5010/20: Data Migration

Two options for data migration:– Fibre channel SAN with Image mode as done with all Storwize models today

– Direct attach SAS storage devices

Direct attach SAS is a special option only available for migrating data from Gen1V3500/3700/5000 systems and DS3200/3500 to the V5020 that has SAS host portsstandard (not sure if this is supported on V5010/30 if 4-port SAS HIC installed)

As with other Spectrum Virtualize platforms (SVC, V7000, etc.), existing data can bemigrated over FC from a large number of supported IBM and non-IBM storage systemsusing Image mode migration capability

– Can use this process to migrate from a Gen1 V3700/5000/7000 to either V5010 or V5020 if


– Can use this process to migrate from a Gen1 V3700/5000/7000 to either V5010 or V5020 ifdesired (must change “layer” to ‘replication’ on V5010/20 system)

Storwize V5030: Migration and Investment Protection

An additional option with the V5030 is the ability to cluster with the V5000 Gen1– Upgrade existing V5000 Gen1 control enclosure software to V7.6.1 and add in a new V5030 control

enclosure to expand the cluster– Assign new workload to new IO group to scale out performance and capacity or,– Migrate volume ownership and data to new IO group to balance workload or,– Migrate all volume ownership and data to new IO group and retire the V5000 Gen1 or use it for testing

or move to remote site and implement replication between it and the new V5000 Gen2

Provides complete protection for existing Storwize V5000 investments– All existing and new storage can be accessed by any host

Migration from existing system with no downtime at all– For systems that support non-disruptive volume move (NDVM)


– For systems that support non-disruptive volume move (NDVM)– No competitive system can make similar claim

Storwize V5030 can virtualize any Storwize model after changing its “layer” setting to‘replication’– Provides conventional Storwize family migration using standard Image mode virtualization capability

Spectrum Virtualize V7.6.1

This is a software release designed to support the new Storwize V5000 Gen2 hardware

There are a few changes which affect all hardware platforms, but are not user visible

No new functions are being introduced, this is basically a roll up of V7.6.0.x fixes and supportfor the new Storwize V5000 Gen2 system

Note the minimum memory per node canister of a Storwize system to support V7.6.1 is 8GB

– Storwize V3700 systems with 4GB of memory per canister can not be upgraded to V7.6.x.x

Hopefully several changes are being made in the GUI where we removed some configurable


Hopefully several changes are being made in the GUI where we removed some configurablesettings that in V7.6.0 resulted in need to use CLI for the following:

– The “-syncrate” for volume mirroring that is also used for formatting new fully allocated volumes

– The ability to enable and disable cache on volumes in SVC GUI

• With Traditional RAID (TRAID), reading from a singledrive or multiple drives and writing to a single sparedrive, the rebuild time is extended due to the sparedrive’s performance. In addition the spares, when notbeing used, sit idle wasting resources.

43

• Improved RAID implementation

– Faster drive rebuild improves availability and enables use of lower cost larger drives with confidence

– All drives are active, which improves performance especially with flash drives

• Spare capacity, not spare drives

• Rotating spare capacity position distributesrebuild load across all drives

• More drives participate in rebuild

– Bottleneck of one drive is removed

– Bottleneck of one drive is removed

• More drives means faster rebuild

– 5-10x faster than traditional RAID

* Note that rebuild rate can be significantly faster if no I/O is occurring to the Array/MDisk

• DRAID rebuild up to 10 times faster than TRAID

• Without host I/O: A 4TB drive can be rebuilt within 90 minutes for an array width of 128drives

• With host I/O: if drives are being utilized up to 50%, the rebuild time will be 50% slower

• Benefit: Lower probability of second drive failing during rebuild on recommendedconfigurations compared to Traditional RAID.

DRAID Performance Goals


configurations compared to Traditional RAID.

• Planned (2016): will only rebuild volume extents actually allocated on the failed drive

48

• Use the recommended configuration from the GUI for creating arrays or from the CLI using‘lsarrayrecommendation’ command

• Use RAID-6 with NLSAS drives for more redundancy as well as for larger 10K SAS drives

• I/O performance for a given number of drives improves with number of arrays, distributed ornon-distributed, specially with SSD drives **

• Do not recommend creating distributed arrays with large number of SSD drives **

DRAID Performance Goals


** With performance enhancements on roadmap for distributed arrays, this recommendationwill no longer be applicable

** The GUI currently does not allow SSDs to be configured as DRAID arrays/mdisks

For SSD drives, create arrays with the same number of drives as you would for non-distributed

(stripe width + 1 rebuild areas e.g. RAID-5, 9 stripe width, 1 rebuild areas). **

For Enterprise and Nearline drives, create arrays of up to 48-60 drives for optimal I/O performanceand rebuild performance results. **

• V7.6 and later supports Distributed RAID 5 & 6

– Distributed RAID-10 is a roadmap item

– DRAID is supported with any SVC, Storwize or FlashSystem running Spectrum Virtualize

• Up to 128 drives in an array with up to 4 rebuild areas

• Up to 10 arrays/MDisks in an I/O Group and a maximum of 32 arrays in a system

– Must be careful not to create lots of small DRAID arrays as it may limit number of TRAID arrays youcan create per I/O Group

o Recommended minimum number of drives for DRAID with HDDs is 24

Distributed RAID


o

• Array/MDisk can only contain drives from the same or a superior drive class

– E.g. 400GB SSDs available to build array, so only superior drives are SSDs > 400GB

– E.g. 450GB 10K SAS available to build array, so only superior drives are 10/15K/SSDs >450GB

– Recommendation is to use same drive class for array/MDisk

50

• Traditional RAID is still supported and default choice in the GUI

– New arrays/MDisks will inherit properties of existing pool you are trying to add it to

– New array width default for RAID5 is 8+P

o If existing MDisks in pool are RAID5 7+P and/or 6+P then GUI will propose 6+P to match lowest width in pool

• Conversion from traditional to distributed RAID is not supported

• Ability to expand an array/MDisk is a roadmap item

• You may mix TRAID and DRAID in the same storage pool

• SAS hardware encryption of DRAID arrays/MDisks is a roadmap item

Distributed RAID


• SAS hardware encryption of DRAID arrays/MDisks is a roadmap item

– A Storwize system with DRAID configured MDisks can be virtualized by SVC or a Storwize V7000Gen2 system that has software encryption enabled and data will be encrypted as it is written tovolumes presented from the DRAID MDisks of the Storwize system

• Just like TRAID, a DRAID5 array/MDisk can lose one physical drive and survive

– If another fails before the bad drive is recovered on to rebuild areas, then the MDisk goes offline asdoes its storage pool

o Thus why we recommend DRAID6 for all arrays/MDisks built from spinning drives

51

• Minimum Drive Count in one array/MDisk

– Distributed RAID5: 4 (2+P+S)

– Distributed RAID6: 6 (3+P+Q+S)

• Maximum Drive Count in one array/MDisk is 128

– If there are 128 disks of same drive class the system should recommend two 64 drive

– Goal is 48-60 per array/MDisk

– 1 to 4 spares worth of rebuild capacity allowed per array/MDisk no matter how many drives in the array

o Default rebuild areas:– Up to 36 drives: 1 spare

Distributed RAID


– Up to 36 drives: 1 spare

– 37-72 drives: 2 spares

– 73 to 100 drives: 3 spares

– 101 to 128 drives: 4 spares

• Recommended stripe width

– RAID5: 9 (8+P)

o Note that this is now the default width for TRAID in the GUI and is default logical width for DRAID-5

– RAID6: 12 (10+P+Q)

o Default for TRAID and DRAID

Fast Format New in V7.5 (Review)

• Online format by default– Create a fully allocated volume and

instantly have access to it– Uses volume mirroring in background– Fast Format is not applicable to thin,

compressed or image mode volumes

• Background format

• mkvdisk– Fast format is turned on by default for

single-copy non-mirror fully-allocatedvolume

– New option –nofmtdisk can disable it– Control format rate with -syncrate


• Background format– A background process with bandwidth

control through –syncrate option willformat the disk gradually

– The default rate is 50% or 2MB/s– Rate can be changed via CLI and in V7.5

and V7.6.1 GUIs (hopefully this makes it)– V7.6.0.x removed the option from GUI

– Control format rate with -syncrate

• The “lsvdisk” cmd will showformatting status

• The “lsvdiskprogress” cmd will showestimated completion time
