Overview
KernSafe iStorage Server is an advanced and powerful, full‐featured software‐only iSCSI Target that fully

conforms to the latest iSCSI Standard 1.0 (former Draft 20). It is an IP SAN solution allowing you to

quickly export existing storages such as disk images, VHD files, physical disks, partitions, CD/DVD‐ROMs,

tapes or any other type of SCSI based devices and even a variety of popular CD/DVD images to the client

machines. The software thus delivers immediate benefits, as it allows storage to be consolidated,

virtualized and centrally managed. iStorage Server also provides RAID‐1 (mirror) feature enabling you to

create two iSCSI devices for mirror backup. Furthermore, iStorage Server also supports a lot of features

such as: VHD (Virtual Hard Disk) target, snapshots, STPI, RAID‐1 and failover, these features are very

important and popular in storage industry world and make iStorage Server suitable for any size of

business.

This article will demonstrate how to remotely backup, restore and view data on a tape device using

KernSafe iStorage Server. Main reason for using tape device for backup is when you will have for

example 3 servers and you would like to backup data from them, before you would need to buy special

hardware for each server to perform a backup. That would be very expensive an inconvenient to use.

But thanks to the iStorage Server you can use any machine that is able to run a Windows operating

system and create a backup on to tape device. Except for that, iStorage Server is also very easy to use.

In this case we will need at two computers ‐ server with installed iStorage Server software and

connected tape device as well as client.

Configuring on iStorage Server
Preparing server for remote tape backup
We will connect to the Generic SCSI Device which in this case will be a tape device on the server
machine running iStorage Server software.

Creating Target
Open iStorage Server Management Console.

Launch the iStorage Server management consolle, press the Create button on the toolbar, the Create
iSCSI Target Wizard will appear.

Select device type.

Chose Generic SCSI.

Press the Next button to continue.

From the list of available devices choose your tape drive.


Choose the Authentication Mechanism. Decide which authentication mechanisms you would want to
use: Anonymous, CHAP, IP Filter or Mixed authentication.

1) Anonymous
All initiators will get full access permission without any authorization required.
2) CHAP (Challenge‐handshake authentication protocol)
All initiators need to specify a CHAP user and secret to connect to the target. iStorage Server has a
built‐in user called “Guest”, which is used for initiators without CHAP secret specified.
3) IP Filters
All initiators will be authorized by the incoming IP address defined by IP Filter roles.
4) Mixed
Security policy is determined by both CHAP and IP Filters.

If you check Inherit security roles from global settings, all client security roles are form global settings,
otherwise, each client will have its own permission.


Enter the name for your target device.

If you check Report as readonly device when initiator cannot get write access, the system will give you
a report when you load the target without write access.

Press the Finish button to continue.

After successfully creating an iSCSI Target, you should be able to see it in your Targets tab in iStorage
Server Management Console.

Logging on to the target
NOTE: Before logging on to the target remote tape, please set up your registry accordingly:

You will need to limit the packet size to 65536 at the initiator side, please follow these steps:
Open registry editor, open the key:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E97B‐E325‐11CE‐BFC1‐
08002BE10318}0000Parameters
please note that the 0000 key may be 0001, 0002... it depends on your system's SCSI adapters.
Find a key (0000 or 0001...) associated with Microsoft iSCSI initiator (you can view the DriverDesc key
value should be Microsoft iSCSI Initiator).
Modify the following key values:
FirstBurstLength: 65536 (Decimal)
MaxBurstLength: 65536 (Decimal)
MaxRecvDataSegmentLength: 65536 (Decimal)
MaxTransferLength: 65536 (Decimal)

After doing the above, please close the registry editor and restart computer.

Open initiator, in this case I will use Microsoft Initiator.

Select the Discovery tab page.

Press the Add button, the Add Target Portal dialog will appear.

Type the IP address and Port of your server. Default port is 3260.

Press the OK button to continue.

Change to Targets tab.

Select the target in the Targets list, and then press the Log On… button.

Then the Log On to Target dialog will appear.

If your iSCSI target is using IP filter or Anonymous authorization, just press the OK button to continue.

Check Automatically restore this connection when the system boots, to log‐on this target automatically
after system boots.


If your iSCSI target is using CHAP user authorization, press the Advanced… button, the Advanced
Settings dialog will appear.

Select CHAP logon information and type User name and Target secret.


When the connection is successfully created, you will see the connection in the Status column.

Now, you may now use the iSCSI Tape Device.
