Supermicro: More Istanbul BIOS Released

June 15, 2009

Supermicro has more systems with BIOS supporting the AMD “Istanbul” 6-core Opteron processor. These all contain the AGESA 3.5.0.0 standard and include 12 more 2P systems including the Twin 1U and Quad 2U systems. This brings Supermicro’s Istanbul support to 23 motherboards.

Dual-Opteron Motherboards (2000-series)

Newly Released: H8DA3-2, H8DAi-2, H8DA8-2, H8DAE-2, H8DMR-82, H8DMR-i2, H8DMT, H8DMT-F, H8DMT-IBX, H8DMT-IBXF, H8DMT+, H8DMT-INF+

Previously Released: H8DM8-2, H8DME-2, H8DMU+

Quad-Opteron Motherboards (8000-series)

Previously Released: H8QM3-2, H8QM3-2+, H8QMi-2, H8QMi-2+, H8QM8-2, H8QM8-2+, H8QME-2, H8QME-2+

Micro-Cloud Anyone? Supermicro Unleashes a (tiny) Monster

May 29, 2009
Supermicro 2021TM-BTRF - 4-nodes in 2U with redundant power.

Supermicro 2021TM-BTRF - 4-nodes in 2U with redundant power.

Supermicro’s been holding the AS-2021TM 4-node-in-2U platform back for several weeks but finally it’s out from behind proprietary OEM’s. We’re talking about the Supermicro 2021TM-B “mini cluster” of course and we’ve been watching this platform for some time.

Why is this a great platform for right now? The H8DMT-F motherboard, supporting only 64GB of DDR2/800 memory, also supports HT3.0 links to enable the slightly higher HT bandwidth of the upcoming Istanbul 6-core processors. The on-board IPMI 2.0 management (WPCM450, supporting KVM/IP and serial-over-LAN) with dedicated LAN port and two inboard USB ports (supporting boot flash) make this an ideal platform for “cloud computing” operations with high-density needs and limited budgets.

The inclusion of the on-board Intel Zoar (82575) dual-port Gigabit Ethernet controller means VMDq support for 4 recieve queues per port using the “igb driver” as we’ve reported in a previous post on “cheap” IOV. An nVidia MCP55-Pro provides Southbridge functions for 6xUSB 2.0, 4x SATA and 1xPCI-express x16 (low-profile) slot. This is a VMware “vSphere ready” configuration.

Each motherboard is installed on a removable try allowing for hot-swapping of motherboard trays (similar to blade architectures). The available x16 PCI-express slot allows for a single, dual-port 10GE card to drive higher network densities per node. An optional 20Gbps Mellanox Infiniband controller (MT25408A0-FCC-DI) is available on-board (PCI-express x8 connected) for HPC applications.

Each node is connected to a bank of 3-SATA hot-swap drive bays supporting RAID 0, 1 or 5 modes of operation (MCP55 Pro NVRAID). This makes the 2021TM a good choice for dense Terminal Services applications, HPC cluster nodes or VMware ESX/ESXi service nodes.

Key Factors:

  • Redundant power supply with Gold Level 93% efficiency rating
  • up to 64GB DDR2/800 per node (256GB/2U) – Istanbul’s sweet-spot is 32-48GB
  • HT3.0 for best Socket-F I/O and memory performance
  • Modern i82575 1Gbps (dual-port) with IOV
  • Inboard USB flash for boot-from-flash (ESXi)
  • Low-profile PCI-express x16 (support for dual-port 1oGE & CNA’s)
  • Hot-swap motherboard trays for easy maintenance
  • Full KVM/IP with Media/IP per node (dedicated LAN port)
  • Available with on-board Mellanox Infiniband (AS-2021TM-BiBTRF) or without (AS-2021TM-BTRF)
