Block 3 Flashcards
Describe components of the UCS that runs UCSM software
UCSM is installed on the flex pods fabric interconnects which runs the UCSM software
Explain characteristics of the UCS manager administration area
Admin area. The admin area contains systemwide settings and troubleshooting. Components major notes include:
Faults, events and audit logs
User management
Key management
Communication manangement
Stats management
Time zone management
Capability catalog
License management
Device connector
Identify the type of port that handles data traffic between the UCS fabric interconnect, and the adapter cards on the blades
Server ports handle all data traffic between the UCS fabric interconnects, and the adapter cards on the blade servers
Explain the term media access control pool
A Mac pool is a collection of network identities. Mack pools are assigned to vNic templates.
Explain the term worldwide name, pool
A worldwide name pool is a collection of worldwide names used by fiber channel vHBA in a Cisco UCS instance
Describe universally, unique identifier pools
A UUID is a 128 bit number that uniquely identifies components worldwide typically manage within UCSM using a UUIID pool
Explain the term service profile
A service profile is a software definition of a server and it’s LAN and SAN network connectivity
Locate the UCS blade system event log
A blades, SEL resides on the blades CIMC in non-volatile memory
Explain the purpose of selecting the preserve identities option for the logical configuration and all configuration back ups
Always select a preserve identities feature when capturing the logical, system, and all configuration backups. This forces back up utility to preserve all data derived from pools. This is critical as without preserved identities the blades will not boot or reboot.
Identify the software used to manage net app storage systems
Also known as data ONTAP, this software is used to manage net App Store systems and provides the capability to read and write data over block or file access protocols
Explain the difference between a SAN and a NAS
NAS-provides file access to the storage system
SAN-provides block level access to the storage system via FC, FCOE, or Internet small computer system interface protocols
Describe an aggregate
An aggregate is a container for the disk manage by a node and is a collection of one or two plexus , depending on whether or not the system admin wants to take advantage of raid level mirroring
Describe a storage virtual machine
A storage virtual machine is a logical entity used to abstract physical resources
Explain the own command system manager interface
The own command system manager GUI is the primary method for managing the storage system, but the CLI also provides administrators command line options for administration
Describe the net app volume level encryption technology
The net app volume encryption feature provides software based volume encryption. NVE is a net app software based encryption technology for encrypting a volumes data at rest once encrypted and encryption key is accessible only to the storage system in order to ensure that the underlying data cannot be read, repurposed or stolen.
Identified the agent handler
Agent handlers (resides on the server) reduce the workload of the server by offloading event processing and McAfee agent connectivity duties. Agent handlers are most effective when located on the same network segment as the EPO database
Describe automatic response
Automatic responses are configured to notify administrators and perform task automation when an event occurs. Once configure, response rules are associated with a group that contains affected systems.
Describe the system tree
The system tree is a hierarchal structure that organizes the system in the network into groups and sub groups. The grouping of the systems allows policies to be applied to the groups instead of individual systems.
