[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] iSCSI: IP fragmentationFolks, IP fragmentation is an issue which will affect the performance, logic and HBA/NIC memory requirements of iSCSI implementations. Note that fragmentation by intermediary switches and routers is not permitted in IPv6 (hence, the DO NOT FRAGMENT bit does not exist in IPv6). With this in mind, and in the interest of optimizing iSCSI performance, I was wondering if it would make sense to require that the DO NOT FRAGMENT bit to be set on IPv4 packets carrying iSCSI and that iSCSI implementations not perform IP fragmentation for IPv6. This will allow for performance optimization if implementations do not have to check for fragmentation and handle reassembly. Any thoughts? Josh
