8 SPARC Enterprise T5140 and T5240 Server Overview Guide • February 2008
You can use the preinstalled Solaris 10 OS, or reinstall a supported version of the
Solaris 10 OS from your network, CD, or downloaded copy. In some cases, if you
reinstall the Solaris OS, you must also install patches. Refer to the SPARC Enterprise
T5140 and T5240 Servers Product Notes for information on the supported OS releases
and mandatory patches for your server.
Hardware-Assisted Cryptography
The UltraSPARC T2 Plus multicore, multithreaded, processors provide hardware-
assisted acceleration of symmetric, asymmetric, hashing and random number
generation cryptographic operations as follows:
■ Asymmetric algorithms – RSA, DSA, Diffie Hellman, and Elliptic Curve
cryptography
■ Symmetric algorithms – AES, 3DES, and RC$
■ Hashing algorithms – SHA1, SHA256, and MD5
The Solaris 10 OS provides the multithreaded device driver that supports the
hardware-assisted cryptography.
Support for Virtualization Through
Logical Domains
The SPARC Enterprise T5140 and T5240 servers support the use of Logical Domains
(LDoms) technology. Through the use of the Solaris OS and the built-in server
firmware, and by installing the Logical Domains Manager software, you can
virtualize the compute services that run on your server. LDoms technology is open
source technology, and is included at no additional cost.
A logical domain is a discrete, logical grouping with its own operating system,
resources, and identity within a single computer system. Each logical domain can be
created, destroyed, reconfigured, and rebooted independently, without requiring a
power cycle of the server.
You can run a variety of applications software in different logical domains and keep
them independent for performance and security purposes.
Each logical domain can be managed as an entirely independent machine with its
own resources, such as:
■ Kernel, patches, and tuning parameters
■ User accounts and administrators
■ Network interfaces, MAC addresses, and IP addresses
