What ports does the HPE AJ864A SAS Switch provide?

It includes 8 external 3Gb SAS ports (SFF-8088) and 16 internal 3Gb SAS ports, with each internal port supporting 2x 3Gb/s SAS links. This setup connects blade servers to external storage in BladeSystem c-Class enclosures, enabling shared SAS domains for up to 8 storage devices.

What is the data transfer rate of the AJ864A?

The switch operates at 3 Gbps SAS using Serial Attached SCSI protocol across all ports. This provides reliable bandwidth for enterprise storage tasks, compatible with SAS 2.0, and supports high I/O workloads in virtualized blade environments without bottlenecks.

What management options are available?

Management is via CLI, HTTP, SSH, and Telnet protocols, allowing remote configuration, monitoring, and zoning of SAS ports. These integrate with standard tools for firmware management and diagnostics, ensuring secure administration in large-scale deployments.

What is the power consumption of this module?

Maximum power rating is 40 watts, making it efficient for dense BladeSystem c-Class chassis. This low draw supports power budgeting in data centers, reducing cooling needs and operational costs for multiple switch installations.

What form factor does the AJ864A use?

It is a hot-pluggable blade switch module designed as a plug-in for HPE BladeSystem c-Class enclosures. This ensures easy installation and maintenance without system downtime, ideal for enterprise rack upgrades.

Is the AJ864A compatible with BladeSystem c-Class?

Yes, it belongs to the BladeSystem c-Class product line, providing SAS expansion specifically for these enclosures. With 16 internal ports linking to blade bays, it enhances storage connectivity in HPE's modular server architecture.
