WORLD WIDE TECHNOLOGY PRESENTS:
Resilient Active/Active Datacenter (RAD) Technology Overview and Demonstration
Tony Berg Director, Data Center Practice
DUSTIN’S SLIDE High Availability Application restart with limited disruption
Continuous Availability Application continues with no disruption (Zero Downtime)
Disaster Recovery Backup and Offsite Replication
What Level of Protection?
COMMON ARCHITECTURE OF TODAY
Site B - Passive Site A - Active Active-Passive Site
MOST of the data on disaster recovery site is used on failure (Outage to move applications)
Server Clusters Host Mirroring
Remote Replication
Other Common Approaches
Server cycles required to mirror or cluster
Application restart required after failover
Remote replication RTO/RPO impact
Network routing and different L2/L3 per site
Pay for expensive DR equipment that isn’t used
Traditional challenges
ACTIVE/ACTIVE - Now a Distributed Reality
Site B - Active Site A - Active
Active-Active Data Access
Federated AccessAnywhere
Enables stretched clusters with zero RPO
Automated recovery with near-zero RTO
High availability within and across VPLEX Metro data centers
MOST importantly DR equipment is used
“RAD” Advantages
Keep Applications Running Utilize Resources at Both Sites
Move & Share Data Non-Disruptively
WHY DISTRIBUTE YOUR DATA CENTER?
1. Increased Availability
2. Increased Asset Utilization
3. Increased Performance
Why Now? Three Main Advancements
A. Networking
B. Storage
C. Virtualization

NETWORKING ADVANCEMENTS:
Layer 2 Extension (OTV – Overlay Transport Virtualization) Inbound Routing Correction (LISP – Location, Identity, Separation, Protocol)
Overlay Transport Virtualization (OTV)
Any Transport! – L2, L3, MPLS
Site 2 Site 3
OTV – Virtual Layer 2 Interconnect
Site 1
VLAN x VLAN x VLAN x
Layer 2 adjacent
Overlay Transport Virtualization - OTV delivers a virtual L2 transport over any L3 Infrastructure
Overlay – A solution that is independent of infrastructure technology and services, flexible over various inter-connect facilities Transport – Transporting services for Layer 2 and Layer 3 Ethernet and IP Traffic Virtualization – Provides virtual connections (connections that are in turn virtualized and partitioned into VPNs, VRFs, VLANs
Real Problems
Solved by OTV
Extension over any
transport (IP, MPLS)
Failure boundary
preservation
Site independence/isolation
Resiliency/multi-homing
Built-in end-to-end loop
prevention
Multi-site connectivity (inter-
and intra-Data Center)
Optimal multicast bandwidth
utilization (no head-end
replication)
Operational simplicity
Ease of site adds/drops

Internet
Device IPv4 or IPv6
address represents
identity and location
Today’s Internet Behavior Loc/ID “overloaded” semantic
x.y.z.1 When the device moves, it gets
a new IPv4 or IPv6 address for
its new identity and location
w.z.y.9
Device IPv4 or IPv6
address represents
identity only.
When the device moves, keeps
its IPv4 or IPv6 address.
It has the same identity
LISP Behavior Loc/ID “split”
Internet
a.b.c.1
e.f.g.7
Only the location changes
x.y.z.1
x.y.z.1
Its location is here!
NETWORKING – LISP (Inbound Routing Correction)
Location, Identity, Separation, Protocol (LISP) What Do We Mean by “Location” and “Identity
AVAILABILITY
High availability
Eliminate storage operations from failover
ACCESS ANYWHERE
SYNCHRONOUS
MOBILITY
Disaster avoidance
Data center migration
Workload rebalancing
ACCESS ANYWHERE
ASYNCHRONOUS
Cluster A Cluster B
COLLABORATION
Instant and simultaneous data access over distance
Streamline workflow
ACCESS ANYWHERE
ASYNCHRONOUS
Move and relocate VMs, applications, and data
over distance
Enable concurrent read/write access to data
across locations
Maintain availability and non-stop access by
mirroring across locations
STORAGE – Meeting Today’s Business & IT Needs
Automatically Balance Loads Across Locations
Enable Concurrent Read / Write Access to Data Across Locations
ACTIVE PASSIVE
Array-Based Remote
Replication
Mirrored I/O Paths
RAC w/ ASM
host-based mirroring

RAC
RPO = 0 and RTO = 0
VPLEX AccessAnywhere
Active Active
Typical configuration:
Oracle RAC with array-based replication for disaster recovery
Areas for Enhancement
• Requires full failover and restart at remote site
• Recovery time objective (RTO) is long
• Complex DR testing
Typical configuration:
Oracle RAC over distance with Oracle ASM (Host-Based Mirroring)
Areas for Enhancement
• Valuable CPU cycles spent on host mirroring
• Error-prone management of host mirroring, groups, paths
• Complex cross-connect SAN networking
VPLEX configuration:
VPLEX simplifies deployment of Oracle RAC over distance
VPLEX Delivers:
• High availability
• Configuration & Management SIMPLICITY
• High-performance replication (no server CPU cycles)
STORAGE – VPLEX & Oracle (Sample of Value)
VIRTUALIZATION – Long Distance vMotion
OTV Ethernet Extension
Any Transport
LD vMotion
ESXi 4.1 Latency RTT 5ms ESXi 5.0 Latency RTT 10ms (Metro vMotion)
DATACENTER A DATACENTER B
Live Migration of VMs from DataCenter A to DataCenter B
Metro vMotion vSphere 5.0 introduces a new latency-aware “Metro vMotion” feature that provides better performance over long latency networks and also increases the round-trip latency limit for vMotion networks from 5ms to 10ms. Previously, vMotion
was supported only on networks with round-trip latencies of up to 5ms.
