SAN and #SANLess clusters for physical, virtual, and cloud environments.

“High Performance and Highly Available SANless SQL clusters in

Azure, AWS or On-Premise”

Mark L RoundVCP : VTSP : MInstLM

SSE, EMEA


Established IT practitioner with over two decades of

experience in the field of international IT.

Career Highlights : worked with some of the industry’s most

exciting “grass roots” pre-IPO technology start-up companies

focused in the business application continuity, converged

infrastructure, and virtualization / cloud eco-systems.

Held a wide variety of roles in IT. Worked with a plethora of

Database Platforms including MS SQL Server;

Guest Speaker at previous SQL-Bits and SQL Saturday

events.

About Me

Uptime and Availability are not synonymous

Servers up / Network Down = Service or App unavailable

Availability measured as class of nines

Some downtime is inevitable

Good HA equals….

Detection of failures as they occur

Elimination of any (ideally ALL) SPOFs

Reliable Crossover (Combining HA + DR)

High Availability?

Q. What is a SANLess cluster?

A. It is a cluster (typically MSWSFC) that uses local storage

instead of a SAN. If you have SAN – you can still use it!

Q. Why would I want a SANLess cluster?

A. There are a few possible reasons:

Deploying SQL into a Cloud (without a SAN)

Eliminate SAN cost and risk (SPOF)

Performance : Use storage options such as PCIe NAND

Flash / SSD and other high speed storage devices that

plug in locally.

Q. Why else would I want a SANLess cluster?

A. There are more reasons……………

Stretch the cluster across geographic locations for disaster

recovery.

– (Including Amazon Availability Zones, Azure Fault

Domains)

Simplify management

Traditional Cluster

Single Point of Failure!

Failover


Servers (Cluster Nodes)

Active Directory (AD) Server

Windows Clusters MUST be joined to a domain

Quorum (Configuration)

determines the number of failures that a cluster can

sustain while still remaining online.

Modern architectures require newer types of quorum conf.

Replace traditional spinning disk with local high speed SSD,

Performance Issue solved?

– Not quite…

• The high speed storage device is now local and a

new SPOF

replication in conjunction with it

o Behold the #SANless High Performance Cluster
