https://community.hpe.com/t5/storevirtual-storage/hp-p4000-vsa-performance-jumbo-frames/m-p/4603334#M759 Hello,<BR />I´ve some performance issues on my HP VSA System.<BR />I´m having a regular speed of about 50MB/s and about 3.000 IPOS. A virtual machine thats directly located on the local server storage will get up to 500MB/s and more that 40000 IPOS! <BR />To get more speed out of the vsa, I want to enable Jumbo Frames, but thats not possibe. When I set the Jumbo Frames option to 9.000 as recommended, it will be reset to default automaticaly. Its the same for the flow control option. I already changed the jumpo frames options ob the dvSwitch Group and on the physical network switch.<BR /><BR />The dvSwitch Group for the storage interface is equiped with two gigabit ethernet interfaces.<BR /><BR />Any advice or further informations required?
