The maximum number of Logical Unit Numbers (LUNs) depends on the system's architecture and configuration. However, based on the provided information, a system can support a maximum of 65,536 LUNs.
Understanding LUNs and their Limits
A LUN (Logical Unit Number) is a logical representation of storage presented to a server. Think of it as a virtual disk. The maximum number of LUNs a system can handle is determined by factors like:
- RAID Group Limits: The reference states that a single RAID group can support a maximum of 256 LUNs.
- Number of RAID Groups: The system itself can have up to 256 RAID groups.
Therefore, the total maximum number of LUNs is calculated by multiplying the maximum LUNs per RAID group by the maximum number of RAID groups: 256 LUNs/RAID group * 256 RAID groups = 65,536 LUNs.
Practical Considerations
While theoretically 65,536 LUNs are possible, the practical limit might be lower due to:
- System Resources: Managing a very large number of LUNs can strain system resources, impacting performance.
- Storage Capacity: The physical storage capacity of the system will ultimately limit the number of LUNs that can be created, regardless of the theoretical maximum.
- Specific Vendor Limitations: Different storage vendors may have their own proprietary limits that differ from the general calculation.
