WHAT IS METADATA?
13© Copyright 2015 EMC Corporation. All rights reserved.
CONVENTIONAL METADATA
1GB Data Chunk
Metadata record (~30 bytes)
1PB = 1,000,000 x 1GB chunks of data
1PB = 1,000,000 x 30 byte metadata records = 30MB of metadata
1PB Array1M x 1GB data chunks30MB metadata
14© Copyright 2015 EMC Corporation. All rights reserved.
WHY GRANULAR METADATA?
• Vastly improved space allocation
• Important for inherent load balancing
• Important for data reduction effectiveness
• Critical for effective copy data management
• Why Content Based Metadata?
PROVIDES SHORTHAND FOR WHAT’S ON THE ARRAY
15© Copyright 2015 EMC Corporation. All rights reserved.
METADATA DE-STAGING
Dual Controller arrays don’t have enough memory to hold granular metadata in memory So they de-stage most
metadata to the array
AND MUST ACCESS THE ARRAY TO RETRIEVE IT AS NEEDED

Private Cloud Case Study: Education Services – Instructor Lead Training
• These workloads are typically very IO
intensive in very short bursts
• Direct user interaction with the UI therefore
requires a desktop like experience.
• Virtual machines generally only have 1 week
life span
• One Template, many Clones

100% SLA
Direct VM Console interaction
Nested Workloads
PRIVATE CLOUD CASE STUDY: VMware HANDS ON LABS
VMs Provisioned over 4 days: 100,000+
LAB Count: 10,000+

Successes
VMworld 2014
• 10,000+ Labs with over 100,000
VMs created over 4 days
-A VM was created every 1.6 seconds
which equals a full complex lab every
14.8 seconds!
• Very low latency
• Efficient use of Physical storage.
-Avg overall efficiency 16:1
EDU – ILT• 100 or more classes running
per week with over 1100 students
• Lab performance has increased by 3x
• Reduced classroom preparation time
28© Copyright 2015 EMC Corporation. All rights reserved.
Future
• XtremIO has allowed us to offer high IOPS
storage tier at relatively low cost per GB
• Formalizing this storage tier and will be
offering it to our internal tenants to run IO
intense workloads outside of the use cases
previously mentioned.

SPACE RECLAMATION UNMAP
QUESTIONUpon a deletion of a VM and /
or File(s) inside a VM, you would
expect the capacity to return
back to the array, right?
YES NO
32© Copyright 2015 EMC Corporation. All rights reserved.
In-Guest
Datastore
When using Virtual
Provisioning Storage
Array, The deletion of a
VM doesn’t cause the
array to claim back the
storage.
It’s a two layer issue,
inside the guest VM and
outside the guest VM (at
the datastore level)

THINK DIFFERENTLY ABOUT VM REPLICATION
• Software Only - Hypervisor based replication solution
• Disaster Recovery and Operational Recovery in VM-level granularity
• Test, failover, failback and production recovery to any point-in-time per VM
• Integrated Management & Orchestration with VMware’s vCenter GUI
40© Copyright 2015 EMC Corporation. All rights reserved.
SUMMARY
VM level replication - any PIT
• Easier OR & DR
• Flexible RPO – up to Zero Data Loss (Sync)
• No Single Point of Failure
• Batch Protection & Multi-Site
Built-in Orchestration
• Automated Discovery & Provisioning
• Resilient to HW changes
• VM power-up order
• Pre/Post Prompt & External Scripts
• VMs Re-IP
