# Resolution
8 Verify that the reported speed and duplex settings for the physical NIC match the hardware expectations and that
the hardware is configured to run at its maximum capability. For example, verify that NICs with 1Gbps are not
reset to 100Mbps because they are connected to an older switch.
9 Verify that all NICs are running in full duplex mode. Hardware connectivity problems might result in a NIC
resetting itself to a lower speed or half duplex mode.
10 Use vNICs that are TCP Segmentation Offload (TSO)-capable, and verify that TSO-Jumbo Frames are enabled
where possible.
Space in GB
The Space in GB chart displays space utilization data counters for virtual machines.
This chart is located in the Storage view of the virtual machine Performance tab.
Table 1‑120. Data Counters
Chart Label Description
Allocated Total amount of logical datastore space provisioned by an administrator for the
virtual machine. It is the storage size up to which the virtual machine files on
datastores can grow. This includes log files, VMX files, and other miscellaneous files.
Allocated space is not always in use.

Not Shared Amount of datastore space that belongs only to this virtual machine and is not shared
with other virtual machines. Only unshared space is guaranteed to be reclaimed for
the virtual machine if, for example, it is moved to a different datastore and then back
again.The value is an aggregate of all unshared space for the virtual machine, across
all datastores.

Chart Analysis
The datastore is at full capacity when the used space is equal to the capacity. Allocated space can be larger
than datastore capacity, for example, when you have snapshots and thin-provisioned disks. You can
provision more space to the datastore if possible, or you can add disks to the datastore or use shared
datastores.
If snapshot files are consuming a lot of datastore space, consider consolidating them to the virtual disk when
they are no longer needed. Consolidating the snapshots deletes the redo log files and removes the snapshots
from the vSphere Web Client user interface. For information about consolidating the data center, see the
vSphere documentation.
