StorMagic SvSAN Architectural Overview and Demonstration

What is SvSAN? • Provides Highly Available Storage between 2 or more servers • Leverages internal host storage or externally attached

• Actively mirrors storage between hosts • Storage is seen as a shared iSCSI volume • Enables advanced hypervisor storage features such as HA, DRS etc SvSAN Synchronous Mirroring

• Centralized Management • Reduces servers footprint

SSD SSD

Synchronous mirroring • SvSAN virtual disks can be mirrored between any pair of VSAs • Active-active, synchronous mirror ̶ ̶

Data can be read or written from either side Writes are not completed until data has been committed to storage on both sides of the mirror

• Standard multi-pathing software to fail over to the other side ̶

̶

̶

vSphere native multi-pathing (NMP) Standard Microsoft DSM No host-side drivers required

SvSAN example host networking configuration

• Simplified networking ̶ ̶

Direct connect storage network Reduce network hardware

• Intelligent storage links ̶

̶

Storage links aggregated to provide higher throughput Link failure and fail back handled automatically

SvSAN example host storage configuration • VSA requirements ̶ ̶

Installed on local storage 1 x virtual CPU 1GB RAM 1Gb networking (10Gb supported)

• Underlying storage configuration ̶ ̶

SATA, SAS, SSD, JBOD Create separate storage tiers with different storage types SvSAN Synchronous Mirroring

• SSD caching ̶

SvSAN summary • Eliminate Downtime ̶ ̶

Synchronously mirrored storage across multiple servers No single point of failure No maintenance downtime ̶

• Eliminate Planned Downtime ̶ ̶

Upgrade seamlessly Replace hardware with no impact

• Centrally Deploy, Manage & Monitor ̶ ̶

Centrally deployed Automated though scripting Central management of thousands of locations No local on site IT Resource ̶ ̶

• Cash savings ̶
