Thicker Than a Blade, Smaller Than a 1U

How do you fit six two-way servers in three rack units?

Taking the next step in the evolutionary squeeze of the generic Linux server into smaller and smaller packages, Dell has packed the equivalent of six two-way 1U servers into a 3U blade enclosure.

The 1655MC, which looks like a thick blade in a box, supports one or two 1.266 GHz Pentium III processors, up to 2GB of SDRAM and one or two Ultra 320 SCSI drives. The chipset is a ServerWorks ServerSet LE30, and the 1655MC also has two integrated Broadcom Gigabit Ethernet interfaces and a USB port.

The power comes at a price in space; RLX packs 24 of its thinner blade servers, sporting one Transmeta or Intel Pentium III processor and two laptop-style IDE drives each, into the same three rack units.

Dell's chassis, which accommodates six 1655MCs, has two hot-plug power supplies for 1+1 redundancy. It includes a built-in KVM switch, plus either one or two managed Ethernet switches.

The chassis with three 1655MCs installed will be priced competitively with three of Dell's comparable 1U servers, said Darrel Ward, senior product marketing manager for PowerEdge servers. "You have a cost crossover at the same size you have a space crossover", he said.

The target customer for the 1655MC will use them in a "value-minded, dense environment" such as a cluster or web farm, Ward added.

"We're including for the first time a deployment tool called Remote Install", he said. The tool will facilitate cloning large numbers of Linux boxes from a single master server.

Dell's Linux options for the 1655MC are Red Hat, Red Hat or Red Hat: customers can order it with 7.3, 8.0 or Advanced Server.

Why is everyone still attaching disks to the blades? Surely some kind of central storage would be more appropriate?

The disks are there to get MSOFT booted up.

Nice but I think IBM's new blades HS20 give you 14 dual CPU servers with lots of options in a 7U and up to 84 servers in a three foot rack.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
