Page 11: Chapter 1 Introduction To The Misan
The miSAN-V-Series models use internal hot-swap disk drives for the virtual tape cache. The total storage capacity for the virtual tape cache is based on the number and configu- ration of the disk drives. For example, the miSAN-V-Series, with six internal disk drives of nearly 750 GB capacity each, will have about 4.5 TB of raw capacity available for the vir-...
Page 12: Features
Standard miSAN-V-Series models include software support for virtual tapes, drives and libraries. Hardware support is offered for data backup and restoration using the integrated SCSI tape drive or via network with the iSCSI interface. The LVD parallel SCSI interface can allow the miSAN-V-Series to connect directly to a host system, either instead of or in addition to the iSCSI interface, allowing for off-network backup and data resto- ration.
Page 13: Functionality
The RAID-based disk storage provides enhanced data integrity and security. The miSAN-V- Series makes efficient use of storage space and network bandwidth. It transfers stored data in raw block format without the overhead of traditional file systems. This can dramatically narrow the time required for even the most extensive backup schedule.
Page 14: Web Control Panel
Introduction to the miSAN Web Control Panel The miSAN-V-Series offers a universally compatible Web Control Panel accessible through a network connection. The Web Control Panel is used for configuring, operating and viewing the status of the miSAN-V-Series in real-time. Multiple clients can access the interface using any Java™-enabled web browser.

Page 16 Introduction to the miSAN SCSI host bus adapter (HBA) to the operating system and application software. To the host system, this appears to be a physical HBA, but all traffic for the iSCSI HBA is encap- sulated for delivery via the network to the remote iSCSI target. Host systems that will transmit commands and data via iSCSI should have iSCSI initiator software installed and configured.

Page 21: Configuring The Network And Iscsi Settings
Configuring the Network and iSCSI Settings The following sections include procedures for configuring the miSAN-V-Series network and iSCSI settings. You must complete the Network and iSCSI device configuration prior to initially using the miSAN-V-Series. Prerequisites Make sure to have the following available to allow for accessing the miSAN-V-Series on a private network: •...
Page 22: Network Setup
Network Setup Certain network parameters must be changed to make the miSAN-V-Series visible on your network. 1. Open the web browser on the computer to the default Management LAN port (“ETH 0”) IP address at http://192.168.1.1 . A dialog box may appear asking for your approval to load the Web Control Panel Java applet.

The initiator and target are identified to each other by iSCSI Names. The iSCSI Names must be unique within the operational domain (networks encompassing the initiator and target), and are designed to be unique worldwide. The iSCSI Name may be permanently assigned to a hardware iSCSI device, or it may be constructed automatically as part of the process of installing an iSCSI software driver.

The Security Officer The security officer account is disabled by default. While the security officer account is disabled, the administrator has all the capabilities of the security officer. Enabling the security officer account takes away encryption-related capabilities from the administrator and reassigns them to the security officer.
Page 27: Deciding How Many Virtual Tapes To Create
Choosing the number of virtual tapes to create involves deciding how to allocate the available miSAN-V-Series storage space. Factors to consider are the size of each physical tape, number of disk drives used by the miSAN-V-Series, total miSAN-V-Series disk storage capacity, tape car- tridge capacity, and historical/estimated compression ratio for backup data.
Page 28: Virtual Standalone Drives
Virtual Standalone Drives Standalone drives are useful in cases where tapes are not assigned for different uses (e.g., when backups are typically large scale, spanning multiple tapes). For a virtual standalone drive, the miSAN-V-Series can automatically change the mounted tape, a method called autoloading, when using multiple tapes during a backup or restore.
Page 29: Creating Virtual Devices
3. Select the “Create virtual tapes…” option. A window will appear showing the current number of virtual tapes and their disk space allocation over the total storage capacity. Caution Make sure to format the disks before creating virtual tapes for the first time.
Page 30: Assigning Virtual Tapes To Virtual Devices
7. Click OK to save changes. The device tree on the “Devices” tab will refresh to update the configuration changes. Note Anytime the number of virtual devices is changed, the virtual tapes should be reassigned to the virtual devices. Assigning Virtual Tapes to Virtual Devices The virtual tapes can be assigned to a virtual device in either a random manner (e.g., VT 1.1, VT 1.3, VT 1.5, and VT 1.9) or a contiguous group (e.g., VT 1.1, VT 1.2, VT 1.3 and VT 1.4).

Page 168 “Offload disk to tapes” is enabled. D2D2T – Disk-to-Disk-to-Tape (D2D2T) is an approach to computer backup and archiving in which data is initially copied to a disk storage device and then periodically copied again to a tape storage device (or to an optical disc drive).
Page 169 iSCSI Initiator – A device that begins an iSCSI transaction by issuing a command to another device (the iSCSI target) to perform a task. Typically an iSCSI host bus adapter is the initiator, but targets may also become initiators, such as when the miSAN-V-Series is configured to use remote iSCSI devices.
Page 170 Optical Disc – An optical disc is an electronic data storage medium that can be written to and read using a low-powered laser beam (e.g., CD-R/W, Blu-ray, ProData). Optical Disc Drive – For the miSAN-V-Series, a SCSI drive that records data on an opti- cal disc.
Page 171 RAID 1 implementations involve two sets of data (hence the term mirror), three or more sets can be created if increased reliability is desired. In a RAID 1 array, storage capacity is determined by the smaller of the two disks in the array. This provides maximum fault tolerance with complete redundancy but minimum data storage capacity, since a host system sees only the capacity of a single disk drive.
