SERVER FINAL JEOPARDY

The SCSI Client is called this.

This is an individually addressable logical unit of storage,

The SCSI server is called this.

Each iSCSI target is defined by one of these two types of names.

SCSI command descriptor block (CDP) starts with this which is followed by the logical block address and then the number of blocks.

SCSI was originally created for this.

Might use file level file transfer protocols.

Network is between the file system and the storage.

Fiber Channel was originally designed for this.

An intelligent head plus a storage array.

Each disk stripe has two parity regions, each calculated separately.

Uses disk striping and parity but distributes the parity across the disks in the array

Parallel access array with dedicated parity disk and large blocks.

Preferred for mission-critical applications but expensive and has the lowest storage efficiency.

This is RAID 5's read penalty.

This is the Fiber Channel NIC card.

The actual connector that a Fiber Channel cable plugs into on the card that connects to the server or the storage device.

This is a high-end FC storage switch with a high port count, scalability and redundancy

This term is used to describe a Fiber Channel topology especially because of its multiple, redundant connections.

FC uses this command protocol.

This algorithm sends requests to servers in a cluster based on which server serving the fewest connections.

This contains the configuration information for the cluster.

Clients access the resources of a cluster via a ___________ address.

When you only have one nic per node you should definitely use these MAC addresses.

Hardware device that receives all incoming client requests and distributes the requests to cluster nodes .

Data is placed in cache and an ack is sent immediately to the host.

This occurs when the cache reaches 100% of its capacity.

Commands are executed based on optimized read/write head movements which may result in the reordering of commands at the front end.

Data that is in the cache but not yet written to disk.

This is how read performance is measured.

Runs over full FC hardware.

Encapsulates FC frames into IP packets and is often used in data replication implementations.

FC running natively over Ethernet?

Every NAS speaks this SAN protocol over IP networks these days.

All the FC protocols encapsulate these types of commands.

A service that is installed on a computer to collect performance data, create alerts and report to the server.

A collection of what information to gather and how to monitor it for a specific product

This SCOM database contains all configuration data and monitoring data that is collected and processed for a default of 7 days.

This defines the events and performance data to collect from computers and what to do with the information after it is collected

You can use SCOM to monitor devices without the use of agents but it will only be able to use a devices ________.

A collection of objects that allow you to gather TCP/IP information

This is an example of one: 1.3.6.1.2.1.4.1

This is a notification message sent from the Agent to the NMS without being asked.

An extension of SNMP that has a group of objects that collect network traffic data above the MAC layer.

An SNMPv3 entity is made up of SNMP applications and an SNMP _______.

The most common measurement of a RAID storage systems overall performance.

The four factors affecting Server Performance.

Keep a second, synchronized copy of data on a separate system.
