  1. 1The SCSI Client is called this.Initiator
  2. 2This is an individually addressable logical unit of storagea LUN
  3. 3The SCSI server is called thisTarget
  4. 4Each iSCSI Target is defined by one of these two types of namesIQN
    EUI
  5. 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
  6. 6SCSI was originally created for thisDAS
  7. 7Might use file level file transfer protocolsa NAS
  8. 8Network is between the file system and the storagea SAN
  9. 9Fiber Channel was originally designed for thisSAN
  10. 10An intelligent head plus a storage arrayNAS
  11. 11Each disk stripe has two parity regions, each calculated separatelyRAID 6
  12. 12Uses disk striping and parity but distributes the parity across the disks in the arrayRAID 5
  13. 13Parallel access array with dedicated parity disk and large blocksRAID 3
  14. 14Preferred for mission-critical applications but expensive and has the lowest storage effieciencyRAID 1 or Mirroring
  15. 15This is the RAID 5 read penaltyAll read penalties are 1 ya dingus
  16. 16This is the fiber channel NIC cardHBA (Host Bus Adapter)
  17. 17The actual connector that a FIber Channel cable plugs into on the card that connects to the server or the storage device.A Port
  18. 18This is a high-end Fiber Channel storage switch with a high port count, scalability, and redundancy.Fiber Channel Director
  19. 19This term is used to describe a Fiber Channel topology, especially because of its multiple redundant connectionsFiber Channel fabric
  20. 20Fiber Channel uses this command protocolSCSI
  21. 21This algorithm sends requests to servers in a cluster based on which server is serving the fewest connectionsLeast-Connection
  22. 22This contains the configuration information for the clusterQuorum or Witness
  23. 23Clients access the resources of a cluster via a _____________ addressVirtual IP address
  24. 24When you only have one nic per node you should definitely use these MAC addressesMulticast
  25. 25Hardware device that receives all incoming client requests and distributes the requests to cluster nodesHardware Load Balancer
  26. 26Data is placed in cache and an ack is sent immediately to the hostWrite-back cache
  27. 27This occurs when the cache reaches 100% capacityForced Flushing
  28. 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)
  29. 29Data that is in the cache but not yet written to diskDirty page
  30. 30This is how read performance is measured.Read Hits : Total # of Reads
  31. 31Runs over full Fiber Channel hardwareFiber Channel Protocol
    (FCP)
  32. 32Encapsulates Fiber Channel frames into IP packets and is often used in data replication implementationsFCIP
  33. 33Fiber Channel running natively over EthernetFCoE
  34. 34Every NAS speaks this SAN protocol over IP networks these daysiSCSI
  35. 35All the Fiber Channel protocols encapsulate these types of commandsSCSI
  36. 36A service that is installed on a computer to collect performance data, create alerts, and report to the serverSCOM agent
  37. 37A collection of what information to gather and how to monitor it for a specific productA Management Pack
  38. 38This SCOM database contains all configuration data and monitoring data that is collected and processed for a default of 7 daysThe Operational Database
  39. 39This defines the events and performance data to collect from computers and what to do with the information after it is collectedA Rule
  40. 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)
  41. 41A collection of objects that allow you to gather TCP/IP informationMIB II
  42. 42This is an example of one: 1.3.6.1.2.1.4.1an OID
  43. 43This is a notification message sent from the Agent to the NMS without being askedIt's a Trap!
  44. 44An extension of SNMP that has a group of objects that collect network traffic data above the MAC layerRMON2
  45. 45An SNMPv3 entity is made up of SNMP applications and and SNMP ____________?an SNMP Engine
  46. 46The most common measurement of a RAID storage system's overall performanceIOPS
  47. 47The four factors affecting Server PerformanceDisk
    CPU
    Memory
    Network
  48. 48Keeping a second, synchronized copy of data on a separate systemReplication
  49. 49ISO Five categories (PCAFS)Performance
    Configuration
    Accounting
    Fault
    Security
  50. 50Disaster Recovery Plan Sections (BERT)Backup Plan
    Emergency Plan
    Recovery Plan
    Test Plan
