Chapter 1. Technical overview 7 Windows Hardware Error Architecture (WHEA) support in the BIOS Trusted Platform Module support. The module is a highly secure start-upprocess from power-on through to the startup of the operating system bootloader. Advanced Configuration and Power Interface (ACPI) support isprovided to allow ACPI-enabled operating systems to access the securityfeatures of this module.System ports and media accessPorts and media access features include: Six USB 2.0 ports, two on the front panel, three on the rear panel, and oneinternal for USB Flash DiskThe Hypervisor model of x3850 M2 includes an integrated hypervisor forvirtualization on a 4 GB USB Flash Disk with VMware ESXi pre-loaded. SeeFigure 1-4 on page 5. An ATI™ Radeon™ ES1000™ SVGA video controller (DB-15 videoconnector on RSA II card as shown in Figure 1-3 on page 4) on the RemoteSupervisor Adapter II Optical drive:– On machine type 7141: One standard 24x/8x IDE CD-RW/DVD-ROMcombo drive– One machine type 7233: SATA CD-RW/DVD-ROM combo drive USB keyboard and mouse System serial port Three SMP expansion ports for use in scalable multinode complex.PowerTwo hot-swap redundant 1440 W power supplies are standard. At 220 V, onepower supply is redundant. At 110 V, the power supplies are non-redundant.1.1.2 x3950 M2: scalable hardware componentsThe x3950 M2 includes the following additional scalable hardware componentsas standard compared to the x3850 M2. The additional components enable thex3950 M2 to scale up to a multinode complex comprising of up to a maximumfour x3950 M2s. ScaleXpander chip (see Figure 1-5 on page 8) One 3.08 m scalability cable (see Figure 1-6 on page 9)
