Direct-Attached Storage

■When your array is on a public network, it is susceptible to viruses, worms, and other malware attacks.

■A variety of security software is available to detect and mitigate these attacks. Some port-scanning and other security software can have an adverse impact on your ability to access data. In extreme cases, some of this software can cause Sun StorEdge 3000 Family arrays to hang.

Since it is not possible to predict the side-effects of all current and future security software products, place your Sun StorEdge 3310 SCSI arrays and Sun StorEdge 3510 FC arrays on private subnets.

Saving and Restoring Configuration Information

An important feature of these management tools is the ability to save and restore configuration information in a number of ways. Using the Sun StorEdge 3510 FC array firmware, the configuration information (NVRAM) can be saved to disk. This provides a backup of the controller-dependent configuration information such as channel settings, host IDs, FC protocol, and cache configuration. It does not save LUN mapping information. The NVRAM configuration file can restore all configuration settings but does not rebuild logical drives.

The Configuration Service software can be used to save and restore all configuration data, including LUN mapping information. It can be used to rebuild all logical drives and therefore can be used to completely duplicate an array configuration to another array.

One powerful feature of Sun StorEdge 3510 FC arrays is their ability to support multiple direct-attached servers without requiring storage switches. They accomplish this using intelligent internal Fibre Channel networks. Servers can be directly connected using built-in external Fibre Channel ports, if available, or add-in Fibre Channel host adapter cards. The Sun StorEdge 3510 FC array automatically configures its ports to match the transfer speed and communication method of each connection.
