Hello Saud,   This behavior is completely normal.  MEM and the array negotiate connections as needed.  Each connection consumes memory on the array, reducing that count means more memory is available for cache.   Even under load, you will not likely every approach the bandwidth of two GbE NICs.  The only way to get that kind of throughput is with large blocksize, totally sequential loads.  So only backup servers and video streaming servers generate that kind of load.   Hypervisors in fact tend to be just the opposite.  Since you have many VMs all doing different IOs the load becomes very random to the storage.  So the storage backend tends to need high IO rates over MB/sec.     With MEM and more than 2x NICs,  MEM will use different NICs to different volumes.  So the NICs will get used, just not every NIC to every volume.  If a NIC fails, it will use another NIC to replace it.  Lastly consider what happens at the storage.  A PS6100 has 4x GbE NICs.  If you did max out 4x NICs on a server you would also max out the array with just one node.   If you have installed SANHQ you will see this pretty clearly.    Regards,  Don   
Hello,  We currently have 1 EQL group which has 1 EQL PS6100XS member. The PS6100XS member currently has 3 datastores. Running ESXi 6.0 u2 and MEM kit 1.3.0.410095 (dell-eql-mem-esx6-1.3.0.410095). The ESXi Host has 4 NICs dedicated to EQL iSCSI. All networking is confirmed to be setup correctly with proper ESXi iSCSI Port Binding.  Prior to installing the Dell MEM kit on the ESXi Host, the active paths to the EQL vSphere datastore shows 4 paths. After installing the Dell MEM kit, it properly sets the pathing to DELL_PSP_ROUTED but reduces the paths to 2 for each datastore: [IMAGE]  Note: there isn't a high volume of traffic yet on the datastores since this is a relatively new environment.  Any thoughts as to why there are only 2 active paths showing and not 4?  -Saud
