https://community.hpe.com/t5/disk-enclosures/sun-storedge9980/m-p/3647485#M18085 As the Sun SE9980 is just a HDS Lightning 9980, I presume that Traffic Manager is in fact just HDLM.<BR /><BR />Assuming that's the case, then no you don't have to use Traffic Manager. <BR /><BR />As well as using Traffic Manager, you can either just use LVM PVlinks for failover, or get VxVM and use Dynamic Multi-Pathing for failover/load balancing.<BR /><BR />HTH<BR /><BR />Duncan Wed, 12 Oct 2005 06:59:30 GMT Duncan Edmonstone 2005-10-12T06:59:30Z https://community.hpe.com/t5/disk-enclosures/sun-storedge9980/m-p/3647484#M18084 Hello,<BR />I would like to know if it is mandatory to install Sun StorEdge Traffic Manager on a rp4440 server so as to have high-availability features (link failover). The server is connected through two switch fabrics to a Sun SE9980 disk array.<BR />Thanks in advance.<BR />Mohamed Wed, 12 Oct 2005 05:36:36 GMT https://community.hpe.com/t5/disk-enclosures/sun-storedge9980/m-p/3647484#M18084 Mohamed Zizi_2 2005-10-12T05:36:36Z https://community.hpe.com/t5/disk-enclosures/sun-storedge9980/m-p/3647485#M18085 As the Sun SE9980 is just a HDS Lightning 9980, I presume that Traffic Manager is in fact just HDLM.<BR /><BR />Assuming that's the case, then no you don't have to use Traffic Manager. <BR /><BR />As well as using Traffic Manager, you can either just use LVM PVlinks for failover, or get VxVM and use Dynamic Multi-Pathing for failover/load balancing.<BR /><BR />HTH<BR /><BR />Duncan Wed, 12 Oct 2005 06:59:30 GMT https://community.hpe.com/t5/disk-enclosures/sun-storedge9980/m-p/3647485#M18085 Duncan Edmonstone 2005-10-12T06:59:30Z
