The Sun T5220 comes with a built-in RAID controller, which supports all of the standard RAID levels (0 – 6). Configuring one or more devices to participate in a RAID Configuration is dead simple, since you can use the Solaris raidctl utility. The last T5220 I configured had a root file system that was going [...]
I have been playing around with the COMSTAR iSCSI and FC port providers for the past few months, and other than a number of problems with the emlxs driver, they appear to work pretty well. As I’ve been experimenting, I wanted to back up my configuration in case something happened to my server. COMSTAR uses [...]
I just saw the following opensolaris putback notice:
PSARC/2009/394 SATA Framework Port Multiplier Support
6422924 sata framework has to support port multipliers
6691950 ahci driver needs to support SIL3726/4726 SATA port multiplier
This is awesome news, and I’m hopeful this will allow me to use one of my external SATA enclosures with OpenSolaris. Time to live upgrade my systems!
With project COMSTAR, you can present logical units to one or more hosts connected via Ethernet or fibre channel. Logical units are managed with the sbdadm utility, which has options to add, delete, list, import and modify logical units. To create a logical unit using a ZFS volume, the path to the ZFS volume can [...]
I recently talked about how you can turn an opensolaris host into a fibre channel storage array. The STMF framework maintains an internal trace buffer with recent activity, which can be extremely useful for debugging problems. To view the contents of the buffer, you can send the string “*stmf_trace_buf” to mdb:
$ echo ‘*stmf_trace_buf/s’ |mdb -k [...]
The COMSTAR (Common Multiprotocol SCSI Target) project was integrated into opensolaris (Nevada) earlier this year, and provides a framework to turn any opensolaris host into a full featured SCSI target. COMSTAR’s power comes from the fact that it supports several transport protocols, which currently includes iSCSI, FCOE and fibre channel. Having just purchased a Brocade [...]
