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


Storage Advancements

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

ACTIVE

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

VIRTUALIZATION – Long Distance vMotion

OTV Ethernet Extension

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.

ARCHITECTURAL CONSIDERATIONS

Legacy Infrastructure Inter-operability challenges and the ability to use legacy infrastructure.

Distance Certain technologies used can only span particular distances.

Cost Containment 99.999% uptime can cost more than 99.9%. Cost of protection is a big consideration

Latency Latency of certain applications and technologies are a definite architectural considerations.
