You have a dead battery on your ACTIVE Controller which disables the caching on your EQL which gives a huge performance drop. Cant speak for the 4100 but we bought 2 new batteries for your 6210XS for 230,- each some month ago.   Also... you have only 6 HDDs in your EQL and run RAID6. Its not what a call an IO Monster    Regards,Joerg
Hi, im administrating a vmware infrastructure based on 2 Esxi and Equallogic. the VMs on both Esxi are very slow. when i checked the Equaloggic i found that the controller battery status is failed. also i noticed that iSCASI connections is 2. i want to know if any of this issues made the VMs slow.   thanks.
