In a multitier implementation, the XProtect Live DB read rate is greater than 50 percent read and less than 50 percent write. The Live DB works best with the server's internal DAS or using external FC or iSCSI storage arrays, such as the Unity and SC series.
Internal DAS storage is ideal for small implementations with a few servers. As an installation grows, the need to optimize storage for reliability, scalability, manageability, and rack space increases. In larger environments, and in virtualized server environments, Unity and SC series arrays in a SAN (FC or iSCSI) configuration are more practical for the Live DB.

- Considerations
-
- With the Unity and SC series the Archive DB is not required, depending on the size of the implementation. If tiered storage is required, both the Live DB and Archive DB can use either FC or iSCSI protocols. For iSCSI, you can use GbE or 10 GB NICs.
Note: When using smaller Unity and SC series arrays with iSCSI, we recommend that the Live DB and Archive DB reside on different arrays.
- Dell EMC recommends that you avoid using Isilon storage for the LiveDB storage tier.
- Although it is possible to use the NFS datastores for the Milestone boot drive in a VMware environment, this configuration with Milestone XProtect has not been tested in the Dell EMC Safety and Security Lab and field tests have been inconclusive.
- With the Unity and SC series the Archive DB is not required, depending on the size of the implementation. If tiered storage is required, both the Live DB and Archive DB can use either FC or iSCSI protocols. For iSCSI, you can use GbE or 10 GB NICs.
