Solaris Operating System
Volume Management and Data Access Technical FAQ
Technical QuestionsQ: Can I use the Solaris 9 Operating System (OS) to access and manage all the storage in my enterprise?
A:
Yes, the Solaris platform with its integral filesystem, volume management and storage management capabilities plus NFS will operate with all forms of storage: Directly attached, SAN and NAS implementations.
Q: What is Solaris Volume Manager?
A:
Solaris Volume Manager is the name for Sun's tightly integrated disk and storage management solution. Based on Sun's Solstice Disksuite technology, it is now a component of the Solaris Operating System and will be maintained as part of Solaris software.
Q: I'm currently using Solstice Disksuite software - can I easily update to Solaris Volume Manager?
A:
Yes. The fact that Volume Management is part of the Solaris 9 OS when it is installed means that you can easily upgrade systems running earlier releases of Solaris and Solstice Disksuite software. This applies to the Solaris 2.6, 7, and 8 platforms.
Q: Can I use Sun Management Center software to manage my storage under the Solaris OS?
A:
Yes. You can manage your storage through SNMP agents which monitor Solaris Volume Manager and notify events to the Sun Management Center application, as well as compatible third party system management solutions.
Q: What tools do I have to manage storage devices under the Solaris Volume Manager?
A:
Solaris Volume Manager has a CIM/WBEM API which provides monitoring and control functions. Command line tools are provided for customers who develop their own scripts for common storage management tasks. In addition, a plug-in for the Solaris Management Console offers GUI-driven wizards to guide administrators through common storage allocation tasks; these Java-based wizards also log the commands which are executed by the wizard to provide scripts which can then be customized to facilitate automation.
Q: Can I run a database such as Oracle directly on Sun's UFS filesystem and still expect good performance?
A:
Yes. Improvements in filesystem performance have been delivered though Solaris 8 software updates, and this trend will continue into the Solaris 9 OS. We already find that many customers rely on Sun's UFS filesystem and volume management. Not only does this deliver adequate performance for the majority of applications, it also reduces cost and risk compared with having to integrate and manage third party solutions for storage access.
Q: I'm currently running NFSv3 - is interoperability guaranteed if I chose to run NFSv4 on some systems?
A:
Yes. NFS is an industry standard. The NFS v4 specification states that it will automatically fall back to NFS v3 or v2. The server or client will both provide this ability.
Q: What additional benefits do I get from running NFSv4?
A:
NFSv4 specifies techniques that will improve client performance and also provide a framework for security. These features will be delivered in the Solaris 9 OS while development of additional features continues.
