Cache/Battery Notes• Cache memory is shared between system memory and

cache memory• All data cache is mirrored for controller failover• Available cache = (total cache – system memory)/2• With 2 Gb cache/controller: (2 GB – 160 MB) / 2 = 944 MB• Write back cache changes to write through mode when a

battery is removed or failed• Power Cooling Unit failure does not cause cache mode

change• Controller Failover causes cache to go into write through

mode• Data is stored in cache of 72 hours @2 GB, > 72 hours @ 1

GB• Data in cache from a power failure is de-staged when

power is returned

Sun StorageTek 6140 Array Data Services● Data Services are premium features. Licensing key

for purchase.● Hard Licensing is used. Licenses are keyed to the

array serial number.● Snapshot● Volume Copy● Remote Replication ● Storage Domains (0 default, 4,8,16, 64 optional)


StorageTek Data Replicator• Storage-based solution• Fibre-channel• Consumes one FC port per controller• Synchronous & asynchronous write mode

– Asynchronous write-order consistency– Dynamic write mode switching

• Adjustable replication I/O priority• Fully integrated with StorageTek Common Array

Manager– Wizard based setup

• DRM will be supported using SMIS 1.1 provider


StorageTek Data Snapshot• Allows creation of a virtual “Point In Time” (PIT) copy of a

volume in the storage array> Fairly instantaneous> Requires less space than a full copy> Mappable to any host> Can be read from and written to> Copied volume termed the “base” volume> Data required to preserve the snapshot contained in

“reserve” volume


Snapshot Reserve Volume• Holds data overwritten in base, or data written to snapshot

volume> Data preserved from base termed COW (copy-on-first-

write) data.• Can reside in different virtual disk from base volume• User defined capacity – defaults to 20% of base• Expandable via DVE• One reserve per snapshot (no shared copy-on-write data)


Data Snapshot Limits• Upto 4 snapshots of a given volume• Max 512 snapshots per StorageTek 6140 array• Base volume, reserve volume and snapshot are all

owned by the same controller


StorageTek Data Volume Copy• Allows creation of a complete byte-for-byte copy of a

volume within the storage array> Copied volume termed “source” volume> Copy of volume termed “target” or “clone” volume

• “Copy Request” Object> Associates source and target volumes (copy pair)> May be created, started, stopped and deleted


Volume Copy – Source Volume• May be a standard volume, snapshot or replication primary

volume• Source volume is read-only during copy process

> While volume copy has status of In Progress, Pending or Failed

> Maintains PiT integrity> Volcopy a snapshot to maintain normal I/O to source

volume during copy• If you need to continue to write to the source

volume, create a snapshot, then create volume copy of the snapshot


StorageTek Volume Copy – Target Volume• Selection

> May be a standard volume, base volume of a disabled or failed snapshot, replication primary

> May reside in a different vdisk to the source volume> Must be at least the same capacity as the source volume

• Identical to the source volume after the copy completes

• As long as copy relationship is maintained> Target copy can be set to read-only> “Re-copy” command uses same source/target


Remote Volume Replication• Storage-based solution• Fibre-channel• Consumes one FC port per controller• Synchronous & asynchronous write mode

– Asynchronous write order consistency– Dynamic write mode switching

• Adjustable replication I/O priority• Fully integrated with StorEdge Configuration Service

– Wizard based setup• DRM will be supported using SMIS 1.1 provider


Replication Rules● Mirroring relationship is on a volume basis● At most one replication relationship per volume

● Primary and secondary volumes must be standard volumes

● An array may have up to 32 replication relationships (primary or secondary)

● A minimum of 2 arrays are required● Both primary and secondary volumes must be

owned by the same controller in each storage array● Secondary volumes are read-only


StorageTek 6140 Array - Technical Summary– New 4 gigabits-per-second

improves time to data access and is backward and forward compatible

– Same high-availability hardware as in previous generations

– Same open SMI/S management software as in previous generations

– Same enterprise-level replication, snapshot, and volume copy

– Common management software across the StrorageTek 6000 family

– Data-in-place upgradeability preserves investment
