72 SANRAD V-Switch User Manu al Introduction to V-Switch Clusters Two V-Switc hes can b e concurr ently connecte d to the sa me FC sto rage devices to balance volum e exposure thus creating a V-Switch clu ster. In a cluster, each V-Switch int eracts in an active-active, peer-to-p ee r fashion with the oth er V-Switch, or neighbor , in the cluster.
Chapte r 5: V-S witch Clust er Configura tion 73 . When creating a cluster, it is recommended that the same port on each V-Switch is used to connect to the same FC storage device. This increases the chance of the storage device receiving the same default storage number on both V- Switches during their auto-discovery cycles.
74 SANRAD V-Switch User Manu al In Figure 33, V-Switch 1 has gone off-line. V-Switch 2 activates V-Switch 1’s IP address and takes over expo sure of Volume 1 to Host 1, repre sented by the orange dashed line.

Chapte r 5: V-S witch Clust er Configura tion 75 Configuring a V-Switch Cluster Setting the V-Switch ID When you con figure a cluster, you must give each V-Switch a dif ferent device ID for proper cluster fun ctioning.

Chapte r 5: V-S witch Clust er Configura tion 79 Example: Every 2 seconds V-Switch 1 sends out a keep alive signal. If, after 6 seconds from the last keep alive sign al, V-Switch 1 does not receive an other keep alive signal from its neighbor, it enters a suspicious interva l .

84 SANRAD V-Switch User Manu al Introduction to Volume Configuration This chapter describes ho w to identify the SAN storage devices and use them to create subdisk s and virtual volumes. Each description includes: A general description and gen eric diagram.
Chapte r 6: Vol ume Configurat ion 85 Identifying Available Storage Devices The V-Switch supports a maximum of 512 disks. Before beginning to c onfigure vir tual volumes, you need to know which storage devices are available.

Chapte r 6: Vol ume Configurat ion 87 The V-Switch also recognizes all write- protected storage device s. Use the CLI command storage details to view a device’s details, in cluding if it is write-protected.
88 SANRAD V-Switch User Manu al Creating a Transparent Volume Transparent volumes cannot be used in further volume hierarchies. Tape devices must be virtualized as transparent volumes.

90 SANRAD V-Switch User Manu al Creating a Subdisk (LUN Carving) The V-Switch supports a maximum of 512 subdisks. You can create on e or more subdisks on a ph ysical disk. The su bd isks can then be converted to sim ple volumes to be used for creating con catena ted, striped and mirro red virtual volumes.

Chapte r 6: Vol ume Configurat ion 93 Creating a Simple Volume The V-Switch supports a maximum of 512 volumes. Before you can build co ncatenated, mirrored and striped volum es , you must create sim ple volumes from each disk or subdis k in your st or age network.
94 SANRAD V-Switch User Manu al If you are working in a V-Switch cluster, this volume must be configured on both V-Switches. Assigning a volum e alias is optional. If you do not include a volume alias in the command, the volume alias will d efault to the subdisk al ias in which the volum e is located.
Chapte r 6: Vol ume Configurat ion 95 Creating a Concatenated Volume The V-Switch supports a maximum of 512 volumes. To accommodate lar ge volumes of data or to best utilize sma ll v olumes spread over several disks , you can concatenate physical vo lumes across storage devices to create a larger virtual vo lume.
96 SANRAD V-Switch User Manu al The system d efault f or the number of childr en being conca tenate d is two. Therefore, you on ly need to specify the number of children for numbers greater than two. Example: If you are working in a V-Switch cluster, this volume must be configured on both V-Switches.
Chapte r 6: Vol ume Configurat ion 97 Creating a Striped Volume The V-Switch supports a maximum of 512 volumes. A striped vol ume has data writt en equitably acro ss two or mo re disks to provide higher read/w rite rates.

100 SANRAD V-Switch User Manu al Creating a Mirrored Volume Use mirroring to create data backups. The V-Switch supports a maximum of 512 volumes. A mirror ed volume i s synchronously writte n into two or mor e vol umes. Mirrored volumes provide protection aga inst data loss from a ph ysical disk crash.
Chapte r 6: Vol ume Configurat ion 101 Example: If you are working in a V-Switch cluster, this volume must be configured on both V-Switches. In Figure 48, a mirrored volume, M irrored 1, is created using t wo children, Simple 6 and Simple 11.

Chapte r 6: Vol ume Configurat ion 103 Creating a RAID 10 and RAID 0+1 You will need two separate comma nds to create a RAID 1 0 or 0+1 volume. RAID 10 first creates mirrored vo lumes and then creates a striped volume of the mirrored volum es. This gives the advantage of both high performance an d data redundancy.

114 SANRAD V-Switch User Manu al initiators. The default identity is assigned position 0, meani ng it is the last scanned. Unlike user-created identities, the default identity cannot be uncoupled from a target.
Chapter 7: Volu me Exposu re and Security 115 If iSCSI initiator WWUI1 tries to lo gin to Target 2, the V-Swit ch first scans Identity B. It does not fin d the initiator listed so it contin ues to scan the next identity, the default identity. The default ident ity blocks al l iSCSI initiators, including WWUI1.
116 SANRAD V-Switch User Manu al Example: If you are working in a V-Switch cluster, each target must be configured on both V- Switches. The target finance is created o n V-Switch 1. The WWUI of Finan ce is billing.sanrad, as shown in Figure 6 2. iscsi target create –ta finance –tn sanrad.

122 SANRAD V-Switch User Manu al Adding Initiators to an Identity If you are working in a V-Switch cluster, each initiator must be added on both V- Switches. After creating an identity, you can begin adding hosts by their iSCSI initiator WWUIs to the identity.

Chapter 7: Volu me Exposu re and Security 125 Assigning Identity Credentials If you are working in a V-Switch cluster, the identity authentication method(s) must be added on both V- Switches. You can require initiator authentication bef ore allowing access to a target and its underlying volume(s).
