Hello experts, My client is thinking about changing one of their servers running Solaris 8 (NIS Hub to mention something) to a server running Solaris 10. The question that i have given is to check the differences or if you wish the status/stability of changing VXvm with DMP (Dynamic Multi Pathing) to a system with ZFS and MPXio. I have made my share of RTFM but not come any closer to an answer.

Folks, I''m trying to figure out whether we should give ZFS / mpxio a shot on one of our research servers, or simply skip it (as we have previously). In Nov 2009 Cindy responded to a thread concerning ZFS device issues, cfgadm, and mpxio: http://mail.opensolaris.org/pipermail/zfs-discuss/2009-November/033496.html I''ve got an x2270 with the Sun EZ-SAS HBA and external SATA

Hi ! I am using MPXIO for doing multipathing across four HBA''s. Now I need to know how much IO/sec each HBA card is serving. With EMC powerpath installed, we could get this using powermt display every=5. is there any way I can use Dtrace to extract this output ? I guess MPXIO just shows one Device name to the OS so dev__pathname won''t be able to tell me per HBA i/O. Regds,

I''m seeing seriously degraded performance with round-robin SAS multipathing. I''m hoping you guys can help me achieve full throughput across both paths. My System Config: OpenSolaris snv_134 2 x E5520 2.4 GHz Xeon Quad-Core Processors 48 GB RAM 2 x LSI SAS 9200-8e (eight-port external 6Gb/s SATA and SAS PCIe 2.0 HBA) 1 X Mellanox 40 Gb/s dual port card PCIe 2.0 1 x JBOD:

Customer asks: Will SunCluster 3.2 support ZFS zpool created with MPxIO devices instead of the corresponding DID devices? Will it cause any support issues?

I''m trying to set up a iscsi connection (with MPXIO) between my Vista64 workstation and a ZFS storage machine running OpenSolaris 10 (forget the exact version). On the ZFS machines, I have two NICS. NIC #1 is 192.168.1.102, and NIC #2 is 192.168.2.102. The NICs are connected to two separate switches serving two separate IP spaces. On my Vista64 machine, I also have two NICs connected in

This may not be the answer you''re looking for, but I don''t know if it''s something you''ve thought of. If you''re pulling a LUN from an expensive array, with multiple HBA''s in the system, why not run mpxio? If you ARE running mpxio, there shouldn''t be an issue with a path dropping. I have the setup above in my test lab and pull cables

Greetings, In looking for inexpensive JBOD and/or RAID solutions to use with ZFS, I''ve run across the recent "VTrak" SAS/SATA systems from Promise Technologies, specifically their E-class and J-class series: E310f FC-connected RAID: http://www.promise.com/product/product_detail_eng.asp?product_id=175 E310s SAS-connected RAID:

Greetings, We''re trying out a new JBOD here. Multipath (mpxio) is not working, and we could use some feedback and/or troubleshooting advice. The OS is oi151a7, running on an existing server with a 54TB pool of internal drives. I believe the server hardware is not relevant to the JBOD issue, although the internal drives do appear to the OS with multipath device names (despite the fact
