Chapter 7: Encryption Key Management

Configuring Scalar Key Manager (SKM) on the Library

182 Quantum Scalar i40 and Scalar i80 User’s Guide

Note: For SKM and KMIP Key Manager, the library actually

uses Transport Layer Security (TLS), a more secure

successor to SSL, to communicate with the encryption

servers.

6 Key Server IP Address or Host Name: In the text boxes, assign your

key servers in the order in which you want failover to occur. The #

column denotes the server failover order. Once you add the servers,

you can change the failover order by clicking the up/down arrow

buttons in the Order column.

Note: SKM requires two servers. KMIP Key Manager requires at

least two servers and can have up to 10 servers for

increased failover capacity.

For an initial key request, the library tries server #1 (the primary

server) first. If server #1 is not available to perform a key request,

the library tries server #2. For KMIP key managers, if server #2 is not

available, the library will try server #3, and so on, in order.

Once the library identifies a server that can perform the request, this

server remains the active server until it fails a key request or the

library is rebooted. At that point, the library starts over and uses

server #1 for key requests.

In the text boxes, type either:

• The IPv4 or IPv6 address of the key server (if DNS is not

enabled), or

• The host name of the key server (if DNS is enabled).

7 Port: In the Port text boxes, type the port numbers corresponding to

the listed servers. The port number listed in the text box must match

the port number on the server.

Note: For SKM the port number is always 6000. You cannot

change SKM port numbers.

For KMIP Key Manager the port number must match the

configured port number on the KMIP key manager server. A

typical port number used for communication between the

KMIP key manager server and the library is port 5696.
