Today’s IT requires continuous access to information

BUT….this can be limited by Infrastructure

DistancePlanned events …

and unplanned events

New Challenges, New Opportunities


New Approach

Getting past these limits requires a new approach to sharing information

within and across data centers…

What is it …

EMC VPLEX


VPLEX – a new way to deliver storage

What is it ?

• Storage virtualization solution made up of hardware and software

What is unique ?

• Distributed coherent cache

• Highly available, scale out cluster architecture

• Distributed storage cluster with arbitration witness


EMC VPLEX

What does it look like …

EMC VPLEX

What can I do with it …


• Replace array seamlessly

EMC VPLEX


legacy array

VPLEX use case – replace array seamlessly

VMFS

VMAX

1. introduce new array to VPLEX

2. „flip the switch“

3. let VPLEX migrate

4. phase out old array

5. host is not aware of change

no change no change



EMC VPLEX

• Increase data availability


VPLEX use case – increase data availability

VMFS

VMAX

1. decide to increase dataavailability

2. „flip the switch“

3. let VPLEX mirror the data

4. host is not aware of change

VNX

no change no change

M1M2



EMC VPLEX

• Increase data availability

• stretched data lun over 2 sites

• VPLEX cache coherency– global cache across sites

• same lun identity on both sites

• active/active access– hosts read and write on both sites
