This document summarizes an EMC presentation on storage essentials. The presentation covered EMC's integration with VMware including features like VAAI, backup and replication solutions using Avamar, and the use of tiered storage technologies like FAST to improve performance. It also discussed reference architectures for VDI deployments using View and how VPLEX can enable live migration of VMs across sites for high availability.

IT Infrastructure Needs to Change
•Too much complexity.
•Too hard to change.
•The business is frustrated.

EMC has ONE vCenter Plug-in to do it
all:
Virtual Storage Integrator (VSI)
• VSI feature menu structure

Understanding VAAI
• VAAI = vStorage APIs for Array
Integration
– A set of APIs to allow ESX to
offload functions to storage arrays
– In vSphere 4.1, supported on
VMware File Systems (VMFS) and
Raw Device Mappings (RDM)
volumes,
– vSphere 5 adds NFS VAAI APIs.
– Supported by EMC VNX, CX/NS,
VMAX arrays (coming soon to
Isilon)
• Goals
– Remove bottlenecks
– Offload expensive data operations
to storage arrays
• Motivation
– Efficiency
– Scaling

Deduplication Is Accelerating
More efficient
Reduced storage
Less bandwidth

VMware Guest Backup
No-cost Avamar agents assure application consistency
• Agent resides in each virtual machine
• Deduplicates within and across virtual
machines – as if they were physical
servers
• Reduces resource contention and
speeds backups
• Provides file-level restore for Windows,
Linux and Solaris

• Deduplication within and

• Load-balancing across
proxy virtual machines
• Change-block-tracking
minimizes recovery time
• File level recovery from
image backup
• Replication provides DR
for backed up VMDKs

vStorage API for Site Recovery Manager
• Storage Replication Adapters
allow for automated
– D/R Setup
– D/R Testing
– Site Failover
• EMC also allows for
automated failback after the
disaster has been mitigated –
managed from the VSI
vCenter plug-in

FLASH 1st Data Strategy
Hot data on fast Flash SSDs—cold data on dense disks
―Hot‖

As data ages, activity
falls, triggering automatic
