Introduction

This session will not cover UCS hardware components

Please check out BRKCOM-1005 UCS Architecture Overview for that

This session will not cover Storage best practices

Please check out BRKCOM-2002 UCS Storage Best Practices for that

This session will not cover Networking in detail

Please check out BRKCOM-2003 UCS Networking Deep Dive w/ VM-FEX for that

On the other hand, this session will cover UCSM quite a bit!

What to expect

UCS Architectural Goals

Administrative Leverage

Deepest possible abstraction of hardware and connectivity

Reduce server provisioning time

Both physical and logical servers

Fully programmable

UCS Manager: Behind the Scenes

UCSM Management Information Model

Summary:

Data Management Engine (DME) contains full representative object model

stored in the Management Information

Tree (MIT)

Interaction with DME occurs via Northbound External Interface Layer

Northbound interfaces all resolve down to XML API

Application Gateways couple UCSM with end points

Release 2.1: Over 15 New Features

15


Service Profile Renaming

FSM Tab Enhancements

Fault Suppression

ID Pool Sequential Allocation

UCSM Upgrade Validation

UCSM Auto Install

Scheduled backups

Operational Enhancements


Users will have the ability to rename a Service Profile in its current place in the org tree

Old IDs (e.g., UUID, MAC, WWN) are retained

New audit logs, events, and faults reference the new name

Existing audit logs, events, and faults from the original Service Profile remain available under the original name

No server reboot is necessary

Only Service Profiles can be renamed. Nothing else.

Customers can simplify operations by aligning

Service Profile names with their naming conventions

Customer benefits

Feature details

Service Profile Renaming

Operational

Enhancements


FSM Tab Enhancement: GUI GUI now shows all FSM Stage details in additional to overall FSM status details.


Sequential ID Pool Allocation

Much better control over SP to ID pools (MAC, WWN, etc.) allocation!


UCSM Upgrade Validation

Starting with Del Mar (2.1) it is possible to do a dry run of system upgrades

Automatic rollback in case of problem


Firmware Auto-install

5 different features actually:

Host Firmware Package creation using simple mode

Deprecation of Management Firmware Package

Removal of ignore compatibility check

Firmware Monitoring

Firmware Auto Install

Install Infrastructure Firmware

Install Server Firmware


VLANs today are not confined to specific Orgs

They are available as a free-for-all resource

Any SP vnic can use any VLAN

2.1 changes this with Org-aware VLANs

Opt-in feature: by default, an Org has access to all VLANs

If enabled, Org is limited to specific VLANs

Org-aware VLANs


Org-aware VLANs


Org-aware VLANs

We created a VLAN called ORGWARE with Org membership = DEMO

SPs that are not in Org DEMO do not see the ORGAWARE VLAN
