Project Background

Current physical DB server challenges• Low utilization : High occupation of rack space

for physical servers• Physical limitation: Difficulty to move services

in the rack• High Cost : Hosting and maintenance of

physical servers dedicated for single projects

Virtual Heterogeneous Database Platform3 |

Project Objective

Support direction of Cloud Enablement by moving 100% of Data Center Virtualization

Provide a Virtualization Platform to host multiple database platforms and solutions requiring high performance

Provide Security and Performance Isolation for services while still achieving high degree of Hardware Utilization

Improve Efficiency of DB Service through automated provisioning and management

VIRTUAL SOLUTIONS

VIRTUAL PLATFORM

• Support Legacy DB Services (SQL2005, 2008, MySQL, etc..)

• Multiple HA Solutions depending on Service Needs (DataKeeper, Replication, AlwaysOn, Load Balancing Solutions etc..)

• Automated Deployment and Configuration• Leveraging Application or Database HA

Solutions (not VMware HA)

• Platform to Support Cloud Design• Utilize local SSD and Caching Technology

to improve IO capability by a factor of x10• Segregation of Services into Different

Virtual Machines• Compute Performance Isolated Per

Service• Security Isolated per Service• Platform to Support Package Apps (see

above)• Full Utilization of Hardware

Our application level solutions can also utilized similar to physical DB servers.

Datakeeper - Alternative Approach to ClusteringTraditional Clustering - Shared SAN Storage Clustering with Local Storage and Datakeeper

Challenges : • No Persistent Shared Storage Options

in AWS – Not cloud ready• Requirement for Shared SAN Storage• Disaster Recovery Requires Expensive

SAN Replication Technology• 1 Copy of the Data• Complex Setup – Raw Device

Mappings

Benefits : • Fully Supported HA Solution in AWS

Public Cloud – more here• Local Storage – no SAN• Low cost solution for keeping

Disaster Recovery site in synch. • Mirror Copy of data can be used to

offload backups and reporting• Simple to configure

Future Flexibility : DC OPs consider to reserve more resources (HBA/Memory/HDD) in server.

Multiple Cluster Nodes Design : We could have enough time to recovery from any hardware failure.

Standard SOP : Exercise and rebuild in pilot test servers. Parallel Pilot : P2V transformation from Production then test

together with service owners. Get Familiar With : Maintenance for Windows Cluster + SQL 2012

AlwaysOn AG + Datakeeper. Performance Impact : While multiple DB Instance running

together in one physical server. Network Loading : Monitor 1GB Ethernet Switch within

DataCenter and cross-site utilization.
