• Supports 4 GB, 8 GB, 16 GB RDIMMs, and 32 GB LRDIMMs with up to 512 GB of total memory
on the system board
Integrated functions:
• Integrated management module 2.1 (IMM2.1), which consolidates multiple management functions
in a single chip
• Concurrent COM/VGA/2x USB (KVM)
• System error LEDs
• Two network ports (two 1 Gb Ethernet ports on the system)
• Supports up to one optional ML2 network adapter
• One optional System Management RJ-45 to connect to a systems management network. This system
management connector is dedicated to the integrated management module 2.1 (IMM2.1) functions
• (Optional) Hardware RAID supportability for RAID level-0, RAID level-1, RAID level-5, RAID level-6,
or RAID level-10
• Wake on LAN (WOL)
Drive expansion bays (depending on the model):
Supports up to eight 3.5-inch SATA (if the storage tray is installed, up to 7 in the storage tray and 1 in the
compute node), two 2.5-inch SATA/SAS, six 2.5-inch hot-swap SATA/SAS (while no PCIe adapter is
installed; if the 2U GPU tray is installed, up to 4 in the 2U GPU tray and 2 in the compute node), or four
1.8-inch solid-state drives (with signal 6 Gb only).
Attention: As a general consideration, do not mix standard 512-byte and advanced 4-KB format drives
in the same RAID array because it might lead to potential performance issues.
