Here is your answer. First, use Chrome as browser, second you need to go with atleast 4vCPU*32GB of RAM & adjust the java heap sizes for SSO, Tomcat management server (TC), inventory server and Profile driven storage to "fine tune" vCenter appliance with embedded or external Oracle DB. I did this and performance gains went 10X. This includes running vSAN enabled clusters. My recommendation that works great based on design documents: vCenter Server Inventory VMware VirtualCenter Management Webservices (tc Server) Inventory Service Profile-Driven Storage Service (sps) Large inventory (More than 400 hosts or 4000 virtual machines)   4GB   12GB   4GB Memory tuning on vCenter server appliance 5.5 Log in to vCenter server appliance using SSH vi /usr/lib/vmware-vsphere-client/server/wrapper/conf/wrapper.conf configuration file, look for JVM memory section and change maxmemory to 4096 Line 66 ##############  JVM Memory#############wrapper.java.initmemory=512wrapper.java.maxmemory=4096 vi /usr/lib/vmware-vpx/inventoryservice/wrapper/conf/wrapper.conf configuration file, find wrapper.java.maxmemory parameter and change it to 12288 Line 116 # Maximum Java Heap Size (in MB)wrapper.java.maxmemory=12288 vi /usr/lib/vmware-vpx/sps/wrapper/conf/wrapper.conf find wrapper.java.maxmemory parameter and change it from 1024 to 4096 Line 154 # Maximum Java Heap Size (in MB)wrapper.java.maxmemory=4096 Reboot vCenter Appliance w/ external DB(1000 hosts)/embedded for lab (100 Hosts) http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=2005086&sliceId=1&docTypeID=DT_KB_1_1&dialogID=294472825&stateId=1%200%20294492358 vSphere 5.5 Documentation Center PS: vCenter 6.0 has much better performance based on my beta testing .. so don't loose hope yet.

So we all are aware of the issues with vCenter 5.5U1 web client and how we are forced to use it to make use of any features of vHardware v10, vDS 5.5 (switch config changes sync issues if an emergency change is made on c# client vDS) VSAN only available through web client, flash issues, sluggish to not responsive issues, and the list goes on with the layout of menus and hard to navigate, SSO issues (still after 5.5 enhancements) So is the vCenter Architecture team @ VMware going to make an effort to hear and act upon the much needed performance enhancements and UI enhancements before adding on more features and SSO type services which majority of the customers don't use, and not force it's customers to continue to loose faith in its vCenter product? Looking for some answers with options to strip vCenter 5.5 U1c installation down along with a promise to address these in vCenter 6.0 release!

After weeks of trial and error, finally figured out how to bypass the "SMART RAID" feature on HP Embedded controller and use it for vSAN. Here is the procedure worth my time to share with you: To enable hba mode on HP P420i RAID controller on ESXi 5.5 here is the procedure that worked for me … just now.. HPSSACLI for ESXi 5.5, vibs are available for individual download and its also built in the HP customized ESXi 5.5U1 iso . syntax http://h10032.www1.hp.com/ctg/Manual/c03934591.pdf Pre-reqs: Make sure disks are wipe clean and no RAID exists Make sure FW is latest v5.42 Make sure ESXi device driver is installed v5.5.0-44vmw.550.0.0.1331820  http://www.vibsdepot/hpq/feb2014-550/esxi-550-devicedrivers/hpsa-5.5.0-1487947.zip Put host in MM, from ilo of ESXi in support mode (Alt+F1) execute the following To View controller config using HPSSACLI with ESXCLI ~ # esxcli hpssacli cmd -q "controller slot=0 show config detail” To enable HBA mode on P420i using HPSSACLI ~ # esxcli hpssacli cmd -q “controller slot=0 modify hbamode=on forced" Reboot the host & perform a scan and walah … disks will show up in vSphere web client for vSAN
So you need some flavor of windows, you cant integrate vCenter 5.5 with like Open source LDAP, can you ?
How did you connect the vCenter to an LDAP group. Did you use MS AD version of LDAP or Linux ?
Thank you guys, this has helped save some time and frustration Shafay Latif
Nope, no luck. After hitting the wall for a few days, I downgraded my host to 3.5 U4. Works great! Shafay

I have the very same problem with two of my ESXi 4.0 stand alone host connecting to NetApp. My ESX 3.5 U4 hosts can see the new LUN but the ESX4.0 can not. Its really frustrating. The vmhba33 path says DEAD at the vCenter on both hosts. I can ping the Vmkernal ports IP address from other hosts so I know the physical network is setup properly I did the install just I would in the past with 3.5U4. I have not used any CLI yet. Any one else with the same senario or is this a new "feature" in vSphere 4.0 ? attached is the screen cap of the iSCSI initiator Shafay
