1 Clusters Your Way. TM 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 Round VCP : VTSP : MInstLM SSE, EMEA

2 About Me 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. 2

3 High Availability? 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) 3

4 SQL High Availability? - How do you protect yours? Multisite Clusters Failover Clusters Database Mirroring (High Safety w/automatic Failover) Log Shipping, Replication, Database Mirroring (High Performance) UPS, RAID, Redundant Hardware 4

5 What is a SANLess Cluster? 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. 5

6 What is a SANLess Cluster? 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 6

7 Traditional Cluster Failover Single Point of Failure!

8 Cluster Components 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. 8

17 #SANLess Clusters for High Performance Environments

18 High Performance requirement? SQL Queries taking too long or timing out DB backup / restore impacting maintenance window User Experience Feedback from system users report sluggish behaviour Legacy Storage Infrastructure no longer performing 18

19 High Performance solution Consider high performance SSD Flash SAN Array If you have the budget? Replace traditional spinning disk with local high speed SSD, PCIe NAND Flash storage or similar Performance Issue solved? Not quite The high speed storage device is now local and a new SPOF o UNLESS you use low latency block level volume replication in conjunction with it o Behold the #SANless High Performance Cluster 19
