Tyan Transport GT28 Overview, Part 1

January 13, 2009

First, let me say that I have been using Tyan Barebones Server products for many years. I have found them both robust in features and reliable. Furthermore, I have focused on AMD Opteron Eco-System products since the products became available due to the I/O benefits of hypertransport and the overall better price/performance of Opteron vs. Xeon offerings.

While I have considerable experience with Xeon systems and have participated in many side-by-side comparisons, I am convinced – as a result of such testing – the I/O systems in Opteron-based platforms are far superior than comparable Xeon FSB systems (front-side bus dependent systems). For low TCO systems, the ability to load I/O elegantly is not just an advantage: it’s a must. This loading factors considerably into TCO where per-node utilization and efficiency are large factors.

That said, the GT28 has a Xeon-based counterpart – the Tank GT24 – to satisfy Xeon-based Eco-Systems. The Tank GT24 does not support quad Gigabit Ethernet nor does it support the built-in Mellanox Infiniband interface. The lack of support for these advanced I/O capabilities is further testament to the weak I/O support of the FSB paradigm. Read the rest of this entry ?


Testing the Tyan Transport GT28 (B2935G28V4H)

January 7, 2009

Over the next few posts I’ll be investigating the Tyan GT28, 1U, 2-socket, dual-node (4-socket total) barebones system. This cost effective system comes some impressive features built-in:

  • 1U, Dual-node Chassis (shared 1000W supply)
  • Dual AMD Opteron 2000-series processor (per node)
  • Shanghai processor support, (AGESA v3.3.0.0 required, BIOS v1.03+)
  • 16 DRAM slots (per node, DDR2/REG/ECC)
  • 2 x Dual Gigabit Ethernet (per node, Intel 82571EB)
  • 20Gbps Infiniband 4x port (per node, B2935G28VHI only, Mellanox MT25204)
  • 2 x Hot-Swap SATA/SAS bays (per node)
  • 1 x Low-profile PCI Express x 8 slot (per node)
  • XGI Volari Z9S Graphics Controller
  • nVIDIA nForce Professional 3600 (NFP 3600)
  • IPMI/SMDC slot (per node, Tyan M3295-2/M3296)

I am testing mine with the M3296 SMDC card with IP/KVM support (Raritan KIRA100, firmware version 1.00, build 5772, GT28 r01). WARNING: The units I received did not come with AGESA v3.3.0.0 updated BIOS and would not boot with a Shanghai processor – requiring a BIOS update with an older 2000-series chip.

After BIOS update on both the SMDC and motherboard, system boots without issue in my test configuration (per node):

I’ll have some screen shots of BIOS settings and configurations (courtesy of the M3296’s) soon. Since the Gigabit Ethernet controllers support both “jumbo frame” and TCP off-load, we’ll try to squeeze-in a few performance comparisons of these features as well.
