- 1The SCSI Client is called this.Initiator
- 2This is an individually addressable logical unit of storagea LUN
- 3The SCSI server is called thisTarget
- 4Each iSCSI Target is defined by one of these two types of namesIQN
EUI - 5SCSI command descriptor block (CDP) starts with this (which is followed by the logical block address and then the number of blocks)Operation Code/Command
- 6SCSI was originally created for thisDAS
- 7Might use file level file transfer protocolsa NAS
- 8Network is between the file system and the storagea SAN
- 9Fiber Channel was originally designed for thisSAN
- 10An intelligent head plus a storage arrayNAS
- 11Each disk stripe has two parity regions, each calculated separatelyRAID 6
- 12Uses disk striping and parity but distributes the parity across the disks in the arrayRAID 5
- 13Parallel access array with dedicated parity disk and large blocksRAID 3
- 14Preferred for mission-critical applications but expensive and has the lowest storage effieciencyRAID 1 or Mirroring
- 15This is the RAID 5 read penaltyAll read penalties are 1 ya dingus
- 16This is the fiber channel NIC cardHBA (Host Bus Adapter)
- 17The actual connector that a FIber Channel cable plugs into on the card that connects to the server or the storage device.A Port
- 18This is a high-end Fiber Channel storage switch with a high port count, scalability, and redundancy.Fiber Channel Director
- 19This term is used to describe a Fiber Channel topology, especially because of its multiple redundant connectionsFiber Channel fabric
- 20Fiber Channel uses this command protocolSCSI
- 21This algorithm sends requests to servers in a cluster based on which server is serving the fewest connectionsLeast-Connection
- 22This contains the configuration information for the clusterQuorum or Witness
- 23Clients access the resources of a cluster via a _____________ addressVirtual IP address
- 24When you only have one nic per node you should definitely use these MAC addressesMulticast
- 25Hardware device that receives all incoming client requests and distributes the requests to cluster nodesHardware Load Balancer
- 26Data is placed in cache and an ack is sent immediately to the hostWrite-back cache
- 27This occurs when the cache reaches 100% capacityForced Flushing
- 28Commands are executed based on optimized read/write head movements which may result in the reordering of commands at the front end.Seek time optimization
(A type of front end queuing) - 29Data that is in the cache but not yet written to diskDirty page
- 30This is how read performance is measured.Read Hits : Total # of Reads
- 31Runs over full Fiber Channel hardwareFiber Channel Protocol
(FCP) - 32Encapsulates Fiber Channel frames into IP packets and is often used in data replication implementationsFCIP
- 33Fiber Channel running natively over EthernetFCoE
- 34Every NAS speaks this SAN protocol over IP networks these daysiSCSI
- 35All the Fiber Channel protocols encapsulate these types of commandsSCSI
- 36A service that is installed on a computer to collect performance data, create alerts, and report to the serverSCOM agent
- 37A collection of what information to gather and how to monitor it for a specific productA Management Pack
- 38This SCOM database contains all configuration data and monitoring data that is collected and processed for a default of 7 daysThe Operational Database
- 39This defines the events and performance data to collect from computers and what to do with the information after it is collectedA Rule
- 40You can use SCOM to monitor devices without the use of agents but it will only be able to use a device's...Responses
(Such as a web application's response to an HTTP request or a router's response to ICMP) - 41A collection of objects that allow you to gather TCP/IP informationMIB II
- 42This is an example of one: 1.3.6.1.2.1.4.1an OID
- 43This is a notification message sent from the Agent to the NMS without being askedIt's a Trap!
- 44An extension of SNMP that has a group of objects that collect network traffic data above the MAC layerRMON2
- 45An SNMPv3 entity is made up of SNMP applications and and SNMP ____________?an SNMP Engine
