Which Aruba stacking technology supports two devices per stack?

Which Aruba stacking technology supports two devices per stack?

• A. VSF
• B. VSX
• C. Both VSF and VSX
• D. Neither VSF nor VSX

Answer: (B)

Two-device stacking is provided by VSX. It creates a single logical switch from two physical Aruba switches, sharing one control plane and management IP. The two units connect via dedicated VSX interconnects and run in an active/standby relationship, so they act as one device even if one unit fails. This exact two-member design is what makes VSX the right choice when you need a stack limited to two switches. VSF, by contrast, is meant for larger stacks; it combines multiple switches into one fabric, not limited to two, so it’s used when you want a bigger, multi-device stack. Therefore, for a setup requiring only two devices per stack, the correct option is VSX.
