When designing an Oracle solution for a customer using XtremIO, it’s important to consider the best

practices for performance and efficiency.

Option OD, “Allocate multiple LUNs per host, Use Thin formatting on the ESXi”, is a recommended

best practice for Oracle environments12.

Allocating multiple LUNs per host can help distribute the I/O load more evenly across the storage

system, which can improve performance1. This is particularly important in Oracle environments,

where there can be a high level of concurrent I/O activity1.

Using Thin formatting on the ESXi is also recommended. Thin provisioning is a storage provisioning

method that optimizes the efficient use of available space. For a thin virtual disk, ESXi provisions the

entire space required for the disk’s current and future activities, but the thin disk uses only as much

storage space as the disk needs for its initial operations3. If the disk requires more space, it can

expand into its entire provisioned space3.

The other options, while they may be part of the overall
