Abstract
  • Worries over the availability of virtual
    infrastructures are being put to rest by rapid
    improvements in virtual high availability (HA).
  • Its time for many organizations to update their
    virtual HA architectures and implement state of
    the art IT best practices.

5
Abstract
  • In this session, HA best practices for
    virtualization are covered, along with available
    tools that allow organizations to take their
    virtual infrastructures beyond simple failover to
    application level orchestration and automation.
  • We will cover high availability options and best
    practices, load balancing, localized HA,
    geographical HA, third-party HA applications and
    failover scenarios.

6
Abstract
  • The following topics are also discussed in this
    session
  • What options are available to prevent downtime
    when failures occur?
  • Understanding virtualization load balancing and
    dynamic migration of virtual machines
  • Understanding virtualization high availability
    and disaster recovery

7
What I Assume You Already Know
  • Assumptions
  • Good understanding of server virtualization
    concepts
  • May or may not already be using virtualization
  • Have, or will have, an application that demands
    high availability

8
By The End Of The Session, Youll Know The
Following
  • Understanding of HA components
  • HA options like load balancing, localized and Geo
    HA
  • What is new in HA
  • HA Tools in virtualization platforms
  • Third-party products available for HA
  • HA best practices for virtualization

FUD
  • Do you have fear, uncertainty and doubt (FUD)
    about your server availability? YES
  • Does virtualization pile more eggs in your one
    basket? YES
  • (Does that create more FUD)? YES
  • Can HA ease FUD? YES

11
FUD
  • Virtualization is great in test and dev, but
    theres no way Im deploying virtualization in
    production without a high availability solution.
    If that virtualization server goes down and I
    dont have a HA solution in place, I will lose my
    job.

12
HA State Of The Union
  • Just about everyone is using virtualization
  • Most arent using virtualization to its full
    ability
  • That ability is expanding every day
  • HA and Load Balancing are a huge benefit -- are
    including and work with all apps

13
Understanding HA What is High Availability?
Lets define
  • High availability is a system design protocol and
    associated implementation that ensures a certain
    absolute degree of operational continuity during
    a given measurement period.
  • In other words, you have low unplanned downtime.

Understanding HA -- Terminology
  • Localized and Geographical High Availability
  • Load balancing vs. resource scheduling
  • Application vs. Server
  • Clustering vs. Failover

18
Understanding HA -- VMware VMotion
19
Understanding HA -- VMware DRS
20
Understanding HA -- VMware HA (VMHA)
21
Understanding HA -- Components Of HA
  • Software
  • Examples VMHA, vLockStep, VMotion and
    third-party
  • Hardware
  • Shared storage -- SAN (iSCSI or Fibre Channel)
  • Servers

22
Understanding HA -- Forms Of Clustering
23
Options Available To Prevent Downtime
  • Host clustering / load balancing
  • Windows Server Clustering
  • Third-party
  • Virtualization high availability
  • VMware High Availability and vLockStep
  • Microsoft Quick Migration
  • Third-party

24
Whats New With Virtualization High Availability?
  • VMwares vLockStep
  • Rumors of Microsoft Live Migration (Nessie)
  • VMware Site Recovery Manager (SRM)
  • New third-party solutions
  • Better use of HA features that you may already
    have
  • P2V HA Clustering

25
HA Tools Using Windows Hyper-V Quick And Live
Migration
  • Quick Migration -- guests moved but restarted
  • Live Migration (coming soon) -- guests moved and
    not restarted (competing with VMotion?)
  • QM and LM compared at
  • http//www.virtualizationteam.com/microsoft/hyper
    -v/live-migration-vs-quick-migration.html
  • Today, no VMotion, SVMotion or VMHA

26
HA Tools Using VMware VMotion and SVMotion
  • VMHA, DRS and Update Manager are dependant on
    VMotion
  • Nothing to configure but compatibility and
    knowing the rules are important
  • VMotion and SVMotion can be used manually to
    prevent downtime

27
HA Tools Using VMware VMHA
  • Built into VMware and VI
  • Easy to configure
  • Can support all applications
  • Guest VMs must restart
  • Creates HA but still has downtime and potential
    for application issues

28
HA Tools Using VMware vLockStep
Virtual Lockstep
  • For a given primary VM, run a secondary VM on a
    different host
  • Sharing virtual disks with primary
  • Secondary VM kept in virtual lockstep via
    logging info sent over private network connection
  • Only primary VM sends and receives network
    packets, secondary is Passive
  • If primary host fails, secondary VM takes over
    with no interruption to applications!

HA Tools Using VMware vLockStep
X
  • vLockstep and HA features work together
  • Mission-critical VMs protected by vLockStep and
    VMHA, remaining VMs protected by VMHA only

HA Tools Using VMware vLockStep
  1. User selects VM on which to enable FT
  2. Secondary VM is automatically created that shares
    disk with primary
  3. When primary VM is powered on, secondary VM is
    started on another host via special kind of
    VMotion
  4. Secondary VM keeps in virtual lockstep
  5. If the primary host goes down, the secondary VM
    will go live and become the primary VM
  6. VMware HA automatically starts another secondary
    VM to restore redundancy
  7. Secondary VM powers off when primary does or when
    FT is disabled
