1.Understand service profiles with statelessmodel2.Configure VSANs, vHBAs and SAN boot3.Understand server pools4.Use virtual identity pools5.Use cloning and templates6.Summarize some of the advanced serviceprofile policies

Add VHBAs

Revisiting SAN Part of Wizard


8/25


SAN Boot in Service Profile Boot Order

3 Key Items:

1.vHBA Name

2.WW PN ofStorage Array

3.LUN #

1.seen by the server

2.LUN mappingis transparent


9/25


Moving a Service Profile to Different Blade

1. Shut server down gracefully (if possible)

2. Disassociate from current blade

3. Associate SP to new blade (can do right away)4. Old blade has to disassociate before avail.

Server Pools Concepts

1.Manually populated or auto-populated

2.Blade can be in multiple pools

3.Associate service profile with pool1.Will choose available (unassociated) blade or wait

2.Will match needs of service profile


12/25


Creating and Manually Populating ServerPool


13/25


Auto-Populating a Server Pool

1. Create empty Server Pool

2. Create Server Pool Qualification

1. Mix and match various criteria: Blade slots

CPU/RAM, etc.

3. Create a Server Pool Policy

blades matching this qualification will automatically beplaced in this pool

4. Auto-placement of the blade into the poolhappens only at blade discoverytime

Identity Pools

1.UUID

2.WWNN

3.WWPN4.MAC


17/25


Creating Pools

Always specify low value and how many values


18/25


Using Pools

Always Choose the Pool Name:

1.Change Association (blade pool)

2.UUID specifier (UUID pool)

3.WWNN specifier (WWNN pool)

4.vHBA form (WWPN pool)

5.vNIC form (MAC Pool)


19/25


Advantage of Pools

Challenge With Pools Without Pools

Managing VirtualIdentiities

Associating done ifresources are

available Will wait untilresources arrive

Must manually assignreassign server

resources

Templates Allows greater speedand flexibility of servercreation

Can update manyprofiles by updating

Must make sure tomake changes tocreated profiles to avoidresource conflicts

CloningAllows greater speedand flexibility in servercreation

Must make sure tomake changes tocreated profiles to avoidresource conflicts

Service Profile Templates

21/25


Creating Template

Looks just like creating profile

Pick a blade pool

Pick the identity pools

Initial or Updating?


22/25


Creating Service Profile(s) from Template


23/25


Unbinding and Rebinding From Template

1.SP from updating or initialtemplate is bound


24/25


Service Profile and Template Cloning

All pool associations retained on cloning

Cloned SP gets new values/blade from pool

Specific virtual identities notcloned
