Three Requirements for HA and DR:• SQL Server Software HA/DR Features• Replication for DR• Clusters for High Availability

Savings

1. Provide HA and DR with SQL Server Standard Edition Licensing

$74,0962. Reduce the Cost of Software Assurance

$35,888

3. Eliminate SAN-based Clusters TCO $735,944

Total $845,928

Simple Strategy for Cutting Costs

VS.SAN-based cluster SIOS #SANLesscluster

• Add SIOS #SANLess Software to a SQL Server WSFC• Host-based, block-level replication synchronizes

local storage in primary and standby servers• Manage replication and recovery at the host OS

level

7

Implementing the Strategy: #SANLess Clusters

• Provides HA and DR with SQL Server Standard Edition

• Reduces the Cost of Software Assurance

• Eliminates the Need for SAN Storage

• Adds Configuration Flexibility• Enables Use of High

Performance SSD

Implementing the Strategy: #SANLess Clusters

1. Provide HA and DR with SQL Server Standard Edition Licensing

9

SQL Server Standard Edition• HA and DR drawbacks• Database Mirroring

• Marked for deprecation in SQL Server 2012

• Labor-intensive manual maintenance

• High Safety Mode • Slows performance on the

primary server• Poorly suited for mirroring

data over long distances or over higher latency connections

Cost Effective Licensing• No significant changes from

2008R2/2012 licensing

• Buy a CAL for each user in your company and then license each server for a nominal fee

• $898 Per Server+$209 per CAL

• High availability included

10

Before SQL Server 2012: License either by sockets, or by server (one CAL per user) $54,000 (list)

11

SQL Enterprise Edition Licensing Costs Have Nearly Doubled

Since SQL Server 2012: License by cores $82,488 (list)

– Costs increase dramatically on larger servers

One SQL Enterprise Edition license for 2 sockets, 6-core processor

2. Reduce the Cost of Software Assurance

12

• Adds up to 25% in Annual Recurring Costs

• Required for:• Cold DR licensing — Create a standby site for DR

without purchasing an additional license• License mobility — Licenses float from one

physical machine to another, needed for VM environments

• License upgrades — Upgrade from SQL Server Standard Edition to Enterprise Edition, without repurchasing the base license

13

Software Assurance

• SQL Server software can be configured so that if one server fails, its processing will be picked up, recovered and continued by another server.

• Beginning with SQL Server 2014, each active server licensed with SA coverage allows the installation of a single passive server used for failover support.

• April 1, 2014 Licensing Document

SQL Server High Availability

Licensing Costs

15

• SQL Server Private Cloud (Virtualization)• Use Standard Edition • Consolidate Your SQL Server Instances• Development Environments and MSDN• Development Instances

Large organizations - may be worth licensing developers with MSDN

It can be much cheaper than buying real licenses Or develop under Developer Edition

16

Additional Ways to Reduce Licensing Costs

3. Eliminate SAN-based Clusters TCO

17

• Storage array-based replication is complex and expensive for DR

• WSFC shared storage cannot span multiple sites

• Storage array-based replication can be used for multisite protection – requires identical SANs in primary and recovery site

• Expensive, vendor lock in, may require the purchase of additional software from the SAN vendor

Why Not Use SAN Replication for DR?

18

Storage Costs: SAN vs #SANLess

• 5-Year SAN TCO1

• $387,068 for small SANs • $735,944, for mid-tier storage arrays

• #SANLess Clusters Eliminate specialized SAN labor expenses• Standard server hardware• Low-cost, easy-to-configure, local

storage and WSFC. • Intuitive configuration wizard and

management console

• Replicate between SAN or #SANLess clusters

• Any combination of physical, virtual, or cloud (public, private, or cloud)

20

#SANLess Clusters Add Flexibility

• Save more than $800,000 dollars

in license costs and SAN five-year TCO

• Easy, cost-effective alternative to traditional clusters – a software ingredient in WSFC

• Enable far more configuration flexibility than is possible in a SAN-based cluster 21

#SANLess clusters save hundreds of thousands of dollars
