DS3400 Controller

• The DS3400 controller has:• 1Gbps bus (64 bit,133 MHz PCI-

X) between the core processor and I/O chips

• The “width” to handle large-block I/O and “speed’ to process small-block I/O

• A single memory that is partitioned between processor and data cache memory.

• The I/O system core integrates the XOR engine and processor.

• Processor focuses on data movement control

• High-speed XOR engine generates RAID parity

Notes: 1. Drives were benchmarked with dual controllers

2. Performance results achieved under ideal circumstances in a benchmark test environment. Actual customer results will vary based on configuration and infrastructure components.

3. The number of drives used does not reflect an optimized test config. The number of drives required could be lower/higher.

Mis-wire Reporting

• When a Mis-wire condition is detected the RAID controller firmware will report the following:

• A “Needs Attention” condition • A critical MEL event indicating the presence of the Mis-wire Condition• A Recovery Action (Recovery Guru) indicating the Mis-wire


System StorageTM


“Needs-Attention” Condition

• The presence of a SAS Mis-wire condition is graphically reported to the user in the form of a “Needs Attention” condition

• When the Mis-wire condition is corrected, the “Needs Attention” condition will be removed.

DS3000 Storage Manager

Based on 6th generation DS4000 Storage Manager code

Task-oriented user interface is intuitive

and simple

Supports RAID levels 0, 1, 3, 5 and 10

Summary page is the “landing page” providing an “at-a-glance” portal-view of the system

Recovery Guru and email diagnostic alerts

Initial Setup Tasks dialog box provides

six steps to setting up the disk system

Benefits of Premium Features

Storage Partitioning• Allows the sharing of capacity across multiple servers• User can define which server(s) can have access to specific data

FlashCopy• Supports utilization of separate data copies, for a variety of uses

such as hot backups or application testing • No affect to production data – remains online accessible• Instantaneous

VolumeCopy• Allows for redistribution of data from older, slower disk drives to

faster and/or higher capacity drives• Optimizes application performance and/or capacity• Complete separate physical copy of data that can be used for

analysis or testing with no effect on production data

What is Storage Partitioning?

• A logical unit consisting of one or more volumes that can be accessed by a single host or shared among hosts

• One or more volumes are mapped to an individual host or host group

• This volume-to-LUN mappingdefines what host or host group will have access to the volume

• Partition access is maintainedat the controller level


System StorageTM


A point-in-time image can be created in seconds

What is FlashCopy?

• A point-in-time (PiT) image of a logical drive

• Logical equivalent of a physical copy

• Features:• Instantaneous copy• Requires less disk space than a full

copy• Map-able to any host • Can be read from, or written to

• Primary uses:• PiT backup image• File restoration• Data mining / analysis

What is VolumeCopy?

• Complete (byte-by-byte) PiT replication of one logical drive (source) to another (target) within a storage system

• Target logical drive also referred to as a clone

• Eliminates I/O contention on the primary logical drive

• Primary uses:• Full PiT data set available for

analysis, mining, testing, backup• Migrating data between

DS3000 Series SAS and SATA Intermix Support

• Integration of SAS and SATA technologies within the same DS3000 series disk system

• SAS drives • High performance• Typically utilized for business critical and transaction-based

applications• SATA drives

• Great cost/GB ratio • Generally deployed for near-line and secondary data where cost

presides over performance

• Purchasing and storage deployment is simplified!!• Organizations can purchase and deploy a single system for all levels of

their data

Intermix Environments

• Multiple drive offerings to satisfy different requirements

• Important to note:• Arrays can only created with the

same type of drives although drive types can be mixed within an enclosure

• Hot spares can only be a spare for like drives

• Therefore, both SAS and SATA hot spares are needed in a mixed drive environment
