Vmware Vsphere - issue with datastore and 10gb network
Hi Gurus,
I've been working with a 10gb network setup with 3x VMware vsphere esxi host, both 5.5 and 6.0. Been trying to create datastore via iscsi 10gb connections, but when going through the process to create the datastores, the hosts can see the iscsi targets just fine, vmkping is fine, but when I complete the datastore creation, it always bombs out with an error. However, when I repeat the same process via 1gb connection on the same 10gb switch, the creation process completes without issue.
So the environment is 3x HP DL360p Gen 8 servers, with 2x 10GB SFP DAC connections and 2x cat5e 1gb connections to the same Dlink 10gb, 12x port switch. I tested datastore creation on a 10gb connection a Thecuse N12000 NAS and a separate white box openfiler NAS, and in both situation, it's consistent, no issues with creating/accessing datastore with 1gb connection, but when using 10gb connection, everything works fine, up until completing the datastore process. In either connections, 1 or 10gb connection, the initial connection testing is fine...Can ping via ip on the network or via the host vmkping utility.
This is the first go around with 10gb connection for me so perhaps I'm missing something?

Hi Andrew,
The host hardware is support and on the HCL.
What do you mean "Misalignment of Jumbo Frames"?

yeah tested that as well. did vmkping -s 9000 to test jumbo frames and it pinged fine.
ASKER
jumbo frames is properly enabled on the host, switch, and storage appliances.
is this the N12000 or N12000 Pro ?
ASKER
there's an issue with the 10gb Switch. When directly connected from host to Storage appliances, there are no issues.
Storage
Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

The hardware is all on the HCL ?
Check the VMware Hardware Compatability Lists HCL here
The VMware Hardware Compatibility List is the detailed lists showing actual vendor devices that are either physically tested or are similar to the devices tested by VMware or VMware partners. Items on the list are tested with VMware products and are known to operate correctly.Devices which are not on the list may function, but will not be supported by VMware.
