[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] RE: iSCSI: Some proposed vendor-specific (X-) keysKen, In my experience, "vendor specific" is a synonym for "non-interoperable". Realistically, if there is any tuning to be done with respect to the iSCSI transport behavior, then it should be done through standardized mechanisms during the login, not through vendor specific mechanisms. The management component already has standard mechanisms for determining such information, including MIBs and CIM objects. The operational components already have standard mechanisms for determining such information, including SCSI INQUIRY commands. I cannot see how this additional (non-standard) mechanism for capturing this information is going to help iSCSI achieve its goals. Those legacy devices that are being supported by non-standard programs and non-standard protocol events are simply NOT compliant iSCSI devices. If anyone cares about using them in an iSCSI environment, they must be upgraded to iSCSI compliance.
