EXP3000 Drive-side Cabling

> All DS3000 products use SAS/SATA disk drives and SAS cabling regardless of the type of host attachment

Support SAS cable 1m or 3m with mini-SAS 4x multilane connectors

> The drive-side cabling is common to all DS3000 products

> When attaching enclosures, drive loops are configured as redundant pairs utilizing one port from each controller.

> This helps ensure data access in the event of a path/loop or controller failure.

> Often referred to as the “Top-Down/Bottom-Up” method

Anytime Administration - Anytime Data

Helps ensure data is always available

EXP HotAdd Technology

> Online capacity expansion, configuration and LUN access

Dynamic Array Expansion (DAE)

> Add drives to existing array (restripes logical drives, defrags array)

Dynamic Volume Expansion (DVE)

> Add available capacity to existing logical drives (OS dependent)

Dynamic RAID Level Migration (DRM)

> Change the RAID configuration of an array (without relocating data)

Dynamic Segment Size Migration (DSS)

> Change the data stripe size (without relocating data)

Dynamic mode switching

> Change between remote mirroring modes

Configuration Flexibility

Tune any attribute to meet any application need

Single storage system supports:

>Multiple RAID levels 0, 1, 1+0, 3, 5, 6

>Multiple drive types, capacities and rotational speeds

>Multiple and various RAID array sizes RAID 1 and 10 – 1+1 up to 56+56 RAID 3, 5 and 6 – 2+1 up to 29+1

>One or more logical drives per RAID array

>Settings defined on a logical drive basis Concurrently maximize performance, capacity and availability

>Dynamic configuration / re-configuration

DACstore Technology

Configuration data is stored on every configured drive.

>Each drive knows its state and status as well as its logical drives’ state and status

>One drive in each RAID array stores the controller- and subsystem-level information

Minimum of three per disk system

DACstore benefits:

>Creates “data intact” drive portability as drives are not bound to a given enclosure or slot

Individual physical drives can be relocated within a system to improve channel utilization (performance / availability)

Individual RAID arrays can be migrated to another system Full systems can be upgraded by simply replacing the controllers

Higher availability

>Critical configuration data stored on every drive, not just a few

> Creates multiple virtual systems from a single disk system

> Logical partitioning provides flexibility

> Volume-to-LUN mapping defines what host or host group will have access to the volume

> Four partitions offered standard with 8, 16, 32 or 64 (DS3500 only) partitions premium feature partition licenses

Accommodates growth and supports a greater number of hosts sharing a single system

> Partition access is maintainedat the controller level

> Heterogeneous host support enables consolidation in multi-platform environments (DS3500 only)

> Storage-based implementation ensures data integrity

ERM/Remote Mirroring - Key Features

Designed to provide:

Synchronous, asynchronous and WOC mirroring modes

> Helps enables administrators to choose the replication method that best meets protection, distance or performance requirements

Dynamic mode switching without suspending the mirror

> Helps enables administrators to accommodate changing application and bandwidth requirements without sacrificing protection

Suspend / resume mirroring with delta resynchronization

> Helps reduce vulnerability associated with reestablishing the mirror

Read-only mirror access (includes FlashCopy creation)

> Helps enable the remote data to be utilized prior to a disaster without sacrificing protection of the primary site data
