Blade Options

The HP 498358-B21 is the HP ProCurve 6120G/XG Ethernet Blade Switch, a managed Layer 2/3 interconnect switch designed specifically for the HP BladeSystem c-Class enclosures (c3000 and c7000). It provides high-density Gigabit Ethernet connectivity with 10GbE uplink capabilities for blade server networking.
Description
• The 6120G/XG is a blade enclosure interconnect switch that installs into the interconnect bays of HP BladeSystem c-Class enclosures, replacing traditional pass-through or basic switches to offer intelligent switching, VLANs, QoS, link aggregation, and basic Layer 3 routing.
• It functions as the network fabric for the blades, providing downlinks to each blade server (16x 1GbE internal) and uplinks for external connectivity (4x 1GbE copper + 2x 10GbE SFP+).
• It is typically deployed in HP BladeSystem environments for blade-to-blade switching, external network access, and converged LAN fabrics in data centers, virtualization clusters, or enterprise campuses.
• The 498358-B21 delivers reliable performance with 16x 1GbE internal downlinks (to blades), 4x 1GbE RJ-45 copper uplinks, and 2x 10GbE SFP+ uplinks, a non-blocking switching capacity of 88 Gbps, and forwarding rate of 65.5 Mpps.
• Reliability is enhanced by redundant power options (via enclosure), ProCurve OS with CLI/web/SNMP management, jumbo frames, and support for Virtual Connect-like features in blade environments.
• Available primarily as refurbished or used units (legacy interconnect from ~2009–2012 era, End-of-Sale/End-of-Support status), refurbished switches are widely sold, tested to HPE standards, and often include mounting hardware.
• HPE originally provided multi-year warranties (now expired); refurbished market options vary by seller (typically 90 days to 1 year); eco-friendly through efficient design and RoHS compliance.
• As an HPE-branded 498358-B21 (HP ProCurve 6120G/XG Blade Switch), it remains a cost-effective solution for legacy HP BladeSystem c-Class networking before migration to newer Virtual Connect or Synergy fabrics.
