Management Host- used to manage the storage array This can be any host that has a network connection to the storage array and has the CAM Management Host Software installed Data Host- used to read and write data to the storage array This can be any host that has a FC connection to the storage array and has the CAM Data Host Software installed Hosts that have both network and FC connection to the storage array can act as both Management and Data hosts Describe the main difference between in-band and out-of-band management In-Band management sends management commands through the FC data path and uses an special agent and access volume Out-of-band management uses Ethernet connections to each controller and uses the ethernet connections for management commands What is the purpose of the "access" volume? To allow communication through the FC path for in-band management List the types of fail over methods Explicit method (RDAC) Implicit method (AVT) Forced (controller fallure) List at least initial configuration steps Name the storage array- set the storage array password Set up users - set module IDs Set the array time Set IP addresses Appendix B-402 Sun StorageTekTM 6000 Product Line Installation and Configuration Copyright2008 SunMicrosystems, Inc All Rights Reserved Sun Services, June 2009, Revision 3.0 Knowledge check solutions Array configuration using Sun Storage Common Array Manager You can mix drive types (SATA and Fibre Channel) in a single module True Why is it important to know what type of data you'll be working with when determining segment size? Segment size can have a major impact on performance for both lOPS and MBps Segment size should be equal to or larger than your 10 size in lOPS environments and be very large in MBps environments What is a preferred controller? A volume is assigned to one of the two active controllers This controller controls the 110 between the volume and the application host along the 110 path What is cache? What effect does it have on a volume? Cache memory is an area oftemporary volatile storage on the controller that has a faster access time than the drive media Cache can speed writes as the host can receive acknowledgement that the write has been written to cache which is faster than writiog to disk For reads, if the requested read is already in cache, it can be immediately sent to the host saving disk access time What is disk scrubbing? A background process that checks the physical disks for defects by reading the raw data from the disk and writing it back This detects possible problems caused by bad sectors of the physical disks before they disrupt normal data reads or writes What does a "global" refer to in relation to a hot spare? The hot spare disk can spare for any disk for which it has enough capacity and same type A hot spare is not assigned to a specific vdisk What is the difference between "reconstruction" and "copy-back" in relation to a hot spare? Reconstruction is the process of building data on a drive from RAID parity or RAID mirror Copy back is the process of copying the data from the hot spare drive after reconstruction completes to the newly replaced drive in a vdisk Knowledge check solutions Copyright 2008 Sun Microsystem~ Inc All Rights Reserved Sun Services June 2009, Revision 3.0 Appendix B-403 Array configuration using Sun Storage Common Array Manager Why should you name your storage array? For identification What can happen if you not set your controller clocks to match your management station? The support data io the Major Event Log, activity log and other data will not have the proper time stamp in case of an issue 10 What part of the storage array takes advantage of the cache block size? What does it with it? The size of the cache memory allocation unit- currently either 4k or 16k This setting if set effectively can improve caching effectiveness SmaU block lOs leave at 4k- large block lOs increase to 16k 11 Why is it important to keep a copy of all the support data? In order to have a record of the storage array when it is optimal - io order to compare in a time of a problem Appendix B-404 Sun StorageTekTM 6000 Product Line Installation and Configuration Copyright2008 SunMicrosystems, Inc All Rights Reserved Sun Services, June 2009, Revision 3.0 Knowledge check solutions Storage Domains True or False A storage domain is created when a host group or a single host is associated with a volume-to-LUN mapping True A host group or host can access volumes with default mappings and specific mappings False You can not use the same LUN number in more than one volume-to-LUN mapping False A Default Host Group shares access to any volumes that were automatically assigned default LUN numbers True Multiple Choice After defining the first specific volume-to-LUN mapping for a host, a Host ports must be defined b the host type can no longer be changed c The LUN number can not be used by other hosts in the topology d The host and host ports move out of the Default host group In a heterogeneous environment, a Each host type must he set to the appropriate operating system during host port definition b Volumes can have more than one volume-to-LUN number c Hosts with different operating systems can share volumes d A host can access volumes with either default mappings or specific volume-to-LUN mappings Customer Scenario Mr Customer has the servers and one storage array (6540) The servers: Three W2003 (each has two single ported HBA's), Linux (one dual ported HBA) and Solaris Spare (one single dual-ported HBA) Knowledge check solutions Copyright 2008 Sun Microsystem~ Inc All Rights Reserved Sun Services, June 2009, Revision 3.0 Appendix B-405 Storage Domains The Finance Department has requested a 'disk' for storing employee expense statements The application to access the employee expense statement will run on both W2003 servers with Microsoft Cluster server software One of the W2003 server will be running the Exchange application and the Exchange Administrator has requested "volumes": one for the database, the other for a log file The Linux server will be used for software development and will require disk space for source code and development tools (2 volumes) The Solaris server will be running the engineering document database and will require volume First draw a diagram showing the servers and the storage, so you and the customer have the same understanding of the requested configuration List the Host Groups that will be created: W2003 with Microsoft Cluster Server List the Hosts that will be created under each Host Group: W2003 host group- two W2003 hosts, W2003, Linux host, solaris host List the number of Host Ports under each Host: host ports for each of the hosts 10 List the Host Types used for each Host Port: Windows 2003 clustered for the host group, Windows 2003 nonclustered, Linux, AIX 11 Will the Default Host Group be empty? Yes 12 How many domains will the customer require? - will be utilized but must buy the license for 13 What needs to be done by the user or storage administrator when an HBA is replaced in one of the servers?

It is really only a logical volume - and no updates are made to the snapshot even if the data changes in the base volume Is snapshot a true disaster recovery feature? Why or why not? A snapshot is not disaster recovery because if the base volume is corrupt or deleted, the snapshot volume is not valid as well What is the maximum number of snapshots that can be created on one base volume? Currently at 6.19 fw snapshots can be created on one base volume What happens if a data block on the base volume is changed more than once after the snapshot is taken? Nothing- snapshot implementation is copy offJrSt write so if the block changes for the second time nothing happens What is the difference between disabling and deleting a snapshot? Disable means that the naming and location of the reserve volume is maintained just no updates to the reserve volume happens Deleting the snapshot removes the name and physical location of the reserve volume Appendix B-408 Sun StorageTekTM 6000 Product Line Installation and Configuration Copyright2008 SunMicrosystems, Inc All Rights Reserved Sun Services, June 2009, Revision 3.0 Knowledge check solutions Integrated data services: Volume Copy Volume Copy source and target volumes can have the same RAID level and configuration True During the copy process, controller A can be the preferred owner of the source volume and controller B can be the preferred owner of the target False Reads and writes can continue to the source volume during a volume copy False What volumes are included in a "copy pair"? Source and the target What is the maximum number of copy pairs that can be in progress at one time? 8copypairs Why would you want to change the copy priority? To complete the process quicker or have less impact on the performance of the array Explain why using snapshot with volume copy is a best practice Use snapshot with volume copy so that reads and writes can continue to the source volume while the copy operation is in progress Knowledge check solutions Copyright 2008 Sun Microsystem~ Inc All Rights Reserved Sun Services June 2009 Revision 3.0 Appendix B-409 Integrated data services: Remote Replication Integrated data services: Remote Replication l Remote replication continuously copies from one volume to another to produce an exact copy of the source volume True Asynchronous mirroring is faster than synchronous mirroring False When using remote replication, your mirrored volume must be located offsite False Why are there two mirror reserve volumes on an array? One for each of the controllers These are used to track the completion of writes to the secondary array - in order to keep the mirrors synchronized No actual data is written to the reserve volumes They are uses for status and control data in relation to the mirror relationships What are the two logs kept in the mirror reserve volume? Briefly describe what each does The delta log and the FIFO log are kept in the mirror reserve The delta log is used to track changes to the primary volume that have not yet been replicated to the secondary volume Therefore, if an interruption occurs to the communication between the two storage arrays, the delta log can be used to re-synchronize the data between the secondary and primary volumes The delta log is a bit map (maximum million bits per mirror), where each bit represents a section of the primary volume that was written by the host, but has not yet been copied to the secondary volume The number of blocks represented by a single bit is computed based on the usable capacity of the primary volume The minimum amount of data represented by a single bit is 64K, that is 128-512-byte blocks For example, for a 2TB volume, each bit will represent a data range of MB The FIFO log is used during Write Consistency mirroring mode to ensure writes are completed in the same order on both the primary and secondary volumes How does "write consistency mode" differ from "asynchronous mode"? With the write consistency mode, the write order to the secondary volume is preserved and is used for multiple replication relationships like database volumes and log volumes AppcndixB-410 Sun StorageTekTM 6000 Product Line Installation and Configuration Copyright2008 SunMicrosystems, Inc All Rights Reserved Sun Services, June 2009, Revision 3.0 Knowledge check solutions What happens if there is a link interruption during the remote mirror process?
