Solaris Filesystem Choices
Linked by John Finigan on Mon 21st Apr 2008 19:00 UTC
Oracle and SUN When it comes to dealing with storage, Solaris 10 provides admins with more choices than any other operating system. Right out of the box, it offers two filesystems, two volume managers, an iscsi target and initiator, and, naturally, an NFS server. Add a couple of Sun packages and you have volume replication, a cluster filesystem, and a hierarchical storage manager. Trust your data to the still-in-development features found in OpenSolaris, and you can have a fibre channel target and an in-kernel CIFS server, among other things. True, some of these features can be found in any enterprise-ready UNIX OS. But Solaris 10 integrates all of them into one well-tested package.

Well, a filesystem is not a volume manager is not a RAID device. They're successive containers for each other.


So, kind of like, storage devices -> zpool -> raidz -> zfs

Stop thinking of ZFS as just a filesystem, and start thinking of it as a storage management system, and you'll start to see that it's not all that different from what you wrote (filesystem on top of volume manager on top of raid on top of storage device).

There must be a shared font of Sun anti-freeze somewhere, because if Sun believes that it eliminates the need for hardware RAID controllers then they don't know what hardware RAID controllers are used for


Other than continuous background verify, faster rebuilds, hot-swappable hardware support, and lower CPU use, there's really not a lot that hardware RAID gives you that software RAID doesn't. And it's a lot easier to move a disk with a software RAID volume on it between systems if hardware dies. Even if moving between non-identical systems.

which is worrying if they're writing a new storage system.


So which is it, filesystem or storage system? ;) You just contradicted yourself.

Hmmmm, no I haven't. Read what you quoted ;-). It seems that even fairly cheap point scoring is beyond you.
