Thinking out of the server box: HP ProLiant MicroServer

By way of Planet Debian, I found Vincent Sanders' article on the HP ProLiant MicroServer he bought for use at home instead of a dedicated NAS appliance.

This is by no means a blade server. It's a squat little box. And the HP ProLiant MicroServer line starts at .

Here are general specs from HP:

What's new

  • Faster processor -- AMD Turion II Neo 1.5GHz
  • Choice of preinstalled OS's includes Microsoft Windows Small Business Server 2011 Essentials

Features

Simple to Own and Easy to Use

  • Server performance but at a PC price
  • Designed to make adding drives or peripherals a minimal effort
  • At a 22 dBA noise level, it is quiet for ergonomic working environment
  • Space-saving; ideal for the small office

Proven HP Dependability and Support

  • HP has built a reputation of dependability by conducting some of the most rigorous and thorough testing in the industry
  • System testing and process control ensures only the most dependable products for the customers
  • Worldwide network of HP trained service

Reliability and Expandability

  • Error checking and correction (ECC) memory minimizes the likelihood of memory corruption
  • RAID 0, 1 prevents data loss and ensures around the clock reliability
  • Up to four LFF SATA pluggable hard disks and up to 8 GB of RAM

That's pretty interesting. It's small, all right. The ECC memory is very server-ish. And not everybody wants or has a rack set up to stuff a server into. This can sit on a table or shelf somewhere.

While there is a model, the best deal seems to be the version with double the RAM (2 GB). The system ships with a smallish 250 GB drive, but the whole point is that you can buy drives for the four bays and just plug 'em in.

Vincent bought his HP box to run Debian, which is what I'd be doing. The HP PDF lists the following as "supported" OSes:

  • Microsoft Windows 2008 Standard Edition R2
  • Microsoft Windows Small Business Server 2011 Essentials
  • Red Hat Enterprise Linux (RHEL)

It doesn't say which versions of RHEL will run, but I imagine that 5.x and 6.x are good to go. And if it runs Debian Squeeze, it will probably run a current Ubuntu release as well.

Looking back at Vincent's original article, he has what looks to me like a somewhat complicated RAID setup for his four 2 TB drives, with 1 GB of ext2 in RAID 1 across four drives for /boot, ext3 with LVM in RAID 5 for the rest of the data, plus a small partition at the beginning for GRUB. I'm a little bit hazy on exactly how one does this.

He cites reports of reliability problems in ext4 as a reason for choosing ext3 for the big RAID partition. I'm running ext3 with LVM in my Debian Squeeze laptop, and it has been 100 percent solid.

I really need to read up on RAID and configuring Linux servers with RAID and LVM ...

The problem with Excito’s Bubba 3 server? It’s nearly $400. So where do I go from here?

I really like the idea of an ARM-based, Debian-running home server, and I really like Excito’s Bubba 3.

The only problem? The Bubba is .75 U.S. (€279.20, exchange rate calculated by Google).

What can I do between those less-than-hardy plug servers for and this item?

Here’s what I’m looking for: * Small form factor * Low power consumption * Linux or BSD OS * Uses standard SATA laptop hard drives * Fanless motherboard and power supply

Server over desktop

I’ve been planning to build a computer for at least a year.

I started with the idea of a mini-ITX motherboard and case to produce a small, low-power desktop, to which I’d hook up a keyboard, mouse and monitor and use as a traditional desktop computer.

Since that time I’ve shed quite a bit of old hardware. And if you want my Sun Sparcstation 20 or Alix Sparcstation 10 clone, come and get them. All the rest of the desktops are gone.

I’m no believer in laptops. Desktops are tougher, easier to fix, better performing. But they stay on a desk.

And while I’m often at a desk myself, it’s generally not the same desk all the time. I’ve begun using Dropbox so my “critical” files are available on more than one computer and are always in sync. Thus far I’m a believer.
