| Frage | Antworten |
| The SCSI Client is called this. | INITIATOR |
| This is an individually addressable logical unit of storage, | LUN |
| The SCSI server is called this. | What is a target? |
| Each iSCSI target is defined by one of these two types of names. | What is IQN or EUI? |
| SCSI command descriptor block (CDP) starts with this which is followed by the logical block address and then the number of blocks. | What is operation code/command? |
| SCSI was originally created for this. | What is DAS? |
| Might use file level file transfer protocols. | What is a NAS? |
| Network is between the file system and the storage. | What is a SAN? |
| Fiber Channel was originally designed for this. | What is a SAN? |
| An intelligent head plus a storage array. | What is NAS? |
| Each disk stripe has two parity regions, each calculated separately. | What is RAID 6 |
| Uses disk striping and parity but distributes the parity across the disks in the array | What is RAID 5? |
| Parallel access array with dedicated parity disk and large blocks. | What is RAID 3? |
| Preferred for mission-critical applications but expensive and has the lowest storage efficiency. | What is RAID 1 or Mirroring? |
| This is RAID 5's read penalty. | What is 1? All read penalties are 1 |
| This is the Fiber Channel NIC card. | What is an HBA (Host Bus Adapter)? |
| The actual connector that a Fiber Channel cable plugs into on the card that connects to the server or the storage device. | What is a port? |
| This is a high-end FC storage switch with a high port count, scalability and redundancy | What is a FC Director? |
| This term is used to describe a Fiber Channel topology especially because of its multiple, redundant connections. | What is the FC Fabric? |
| FC uses this command protocol. | What is a SCSI? |
| This algorithm sends requests to servers in a cluster based on which server serving the fewest connections. | What is Least-Connection? |
| This contains the configuration information for the cluster. | What is the Quorum or Witness? |
| Clients access the resources of a cluster via a ___________ address. | What is a virtual IP address |
| When you only have one nic per node you should definitely use these MAC addresses. | What is multicast? |
| Hardware device that receives all incoming client requests and distributes the requests to cluster nodes . | What is a hardware load balancer? |
| Data is placed in cache and an ack is sent immediately to the host. | What is write-back cache? |
| This occurs when the cache reaches 100% of its capacity. | What is forced flushing? |
| Commands are executed based on optimized read/write head movements which may result in the reordering of commands at the front end. | What is seek time optimization ( a type of front end command queueing)? |
| Data that is in the cache but not yet written to disk. | What is a dirty page? |
| This is how read performance is measured. | What is read hits:total number of reads |
| Runs over full FC hardware. | What is FCP (fiber channel protocol)? |
| Encapsulates FC frames into IP packets and is often used in data replication implementations. | What is FCIP? |
| FC running natively over Ethernet? | What is FCoE? |
| Every NAS speaks this SAN protocol over IP networks these days. | What is iSCSI? |
| All the FC protocols encapsulate these types of commands. | What is SCSI? |
| A service that is installed on a computer to collect performance data, create alerts and report to the server. | What is a SCOM agent? |
| A collection of what information to gather and how to monitor it for a specific product | What is a Management Pack? |
| This SCOM database contains all configuration data and monitoring data that is collected and processed for a default of 7 days. | What is the operational database? |
| This defines the events and performance data to collect from computers and what to do with the information after it is collected | What is a rule? |
| You can use SCOM to monitor devices without the use of agents but it will only be able to use a devices ________. | What are responses (such as a web applications response to an HTTP request or a routers response to ICMP)? |
| A collection of objects that allow you to gather TCP/IP information | What is MIB II? |
| This is an example of one: 1.3.6.1.2.1.4.1 | What is an OID? |
| This is a notification message sent from the Agent to the NMS without being asked. | What is a Trap? |
| An extension of SNMP that has a group of objects that collect network traffic data above the MAC layer. | What is RMON2? |
| An SNMPv3 entity is made up of SNMP applications and an SNMP _______. | What is an SNMP engine? |
| The most common measurement of a RAID storage systems overall performance. | What is IOPS? |
| The four factors affecting Server Performance. | What are disk, CPU, Memory and Network? |
| Keep a second, synchronized copy of data on a separate system. | What is replication? |
| ISO Five categories: PCAFS | What are performance, configuration, accounting, fault and security? |
| Disaster Recovery Plan Sections: EBRT | What are Emergency, Backup, Recovery and Test plans? |
| What is the SCSI ID of the Disk indicated by a star in the diagram? | What is C0:T1:D2? |
