The Future of Home Storage

Homes now need data storage as well as closets...

This is part of an ongoing series of longer articles I will be posting every Sunday as part of an experiment in offering more in-depth content.

Along with my professional focus on enterprise storage systems, I’m enamored of home networking, and recently passed the three terabyte mark at home! This got me thinking about where home storage is heading.

As you can see in the photo, my office closet is overflowing with computer equipment (and one sweet guitar), but my data storage is much better organized. I have a hacked Linksys NSLU2 with 500 GB as a file server, a 500 GB PC backup disk, a 160 GB Time Machine disk, 1 TB of TiVo storage, and the rest. But wouldn’t it be nice if this could all be combined into some kind of super home server?

Making the Switch to Digital Music at Home

After sticking staunchly to real CDs for home listening, I finally succumbed and expanded my terabyte house into the digital audio server domain. In the end, it was audiophile Mark Schlack from TechTarget who won me over - if digital audio is good enough for him, then it ought to be good enough for me!

Although both of my TiVos can browse and play mp3 files, they require the television to be on and a special server running on a PC (or so I thought, more on that later). It was critical that any digital music solution be directly browsable and searchable using a remote control, since the kids perk up whenever they hear the big tube on our Sony TV burp to life.

Although there are a good many home music players available, two immediately rose above the rest: the Slim Devices Squeezebox, and the Roku SoundBridge M1001. Both are somewhat similar in that they are designed to connect to a home network and browse and play digital music in a variety of formats to an audio receiver. I rejected out of hand all those devices that lacked their own display, sadly including Apple’s intriguing AirPort Express with Air Tunes.

My research quickly revealed that the Squeezebox was the audiophile-preferred solution with its fancy Burr-Brown digital audio converters, while the SoundBridge was the hackers choice with its open interfaces and wider server compatibility. It was widely claimed that only the Squeezebox supported lossless codecs, but I found that this was not the case - although FLAC must be transcoded, the SoundBridge does support ALAC and even WAV for high quality audio. The difference in DACs made no difference to me, since I would be using a digital (S/PDIF) connection to bypass the SoundBridge’s DAC in favor of the one in my Denon receiver.

In the end, the flexible SoundBridge won me over with its wide range of interfaces. It can browse and stream an iTunes library directly, since Roku licensed Apple’s DAAP API. There are a variety of other DAAP servers that can use, too, including Slim Devices Slimserver! But I settled on the open source Firefly (nee mt-daapd) server, since it was full featured, and lightweight enough to run on an embedded NAS server like the Linksys NSLU2, which I intended to add in short order. The SoundBridge also has an open API and telnet interface!

Making my choice even sweeter, at $127, the SoundBridge was half the price of the Squeezebox, too! I placed my order, and thenerds.net delivered it the very next day, even though I chose ground shipping!

The SoundBridge is amazing! It does exactly what I wanted, letting me listen to the tunes stored on my wife’s and my laptop as well as my home PC server without any configuration required. Once I discovered that you can quickly move from letter to letter with the right and left buttons, locating the right song from our 7800-tune collection could not be easier either.

The one major letdown that I had is that Apple will not allow any other hardware, even under license, to play the protected m4p files purchased from iTunes. Although most of my music is ripped from CD, I have got a few dozen iTunes purchased songs. There is a way to crack that DRM protection on these files, but it galls me to have to hack them open just to listen to them!

All in all, I’m very pleased with my new digital music solution at home. I’m seriously considering buying Roku’s SoundBridge Radio, which would let me wirelessly browse and play music anywhere within range of my access point. And I did add that home server - more on this next time.

Where is Linux in Storage?

Marc Farley’s challenge of listing all the devices on our home networks got me thinking –I’ve got an awful lot of Linux devices, but all of them are infrastructure rather than interactive PCs. Of the 10 devices currently attached my home network, four are Linux based (two TiVos, a Linksys router, and Linksys NAS), three are Windows PCs (two Vista, one server 2003), and the rest run various embedded operating systems (a Roku SoundBridge, an HP printer, and a 3Com Audrey running QNX).

Notice that all of my PC’s run windows, while all of my servers run Linux! This got me wondering what role Linux plays in enterprise storage. Sure, Linux has a huge role to play on the computing side of the equation. But which enterprise storage devices are based on a Linux kernel?

Xiotech made a big splash a few years ago by announcing that they would switch from a proprietary operating system to Linux. I remember seeing Open-E’s Linux based iSCSI software somewhere, and hearing that Snap Appliance (now part Adaptec) of was using it as well. I consulted LinuxDevices.com and found out about Infrant (now part of NetGear), MaXXan (nee CipherMax), and Raidtec.

There have got to be more! So tell me, who is using Linux as their embedded kernel and why? Was it for convenience, hardware support, or perhaps a financial decision?

These computers are not junk!

Marc Farley challenged us storage geeks to wave our junk flags and reveal just how many computers we have. Well, I’m really not sure… Let’s see - in order of usefulness…

Networked:

  1. Dell XPS M1210 laptop (killer!) with 120GB internal and 500 GB Western Digital My Book backup drive
  2. TiVo Series 3 with 250 GB (yeah yeah not yet upgraded)
  3. TiVo Series 2 with 140 GB
  4. Homebrew Celeron 4 desktop with 320 GB
  5. Wife’s Compaq laptop with 100 GB
  6. Sa-weet HP Photosmart all-in-one with no storage (but it’s networked!)
  7. Linksys 54G running Tomato (16 MB flasher!!)
  8. 2 3Com Audreys (16 MB flash bay-bee!)
  9. Old junker laptop with 10 GB
  10. Virgin Webplayer Internet appliance with 64 MB disk-on-chip
  11. Toshiba Portege booting from a 4 GB CompactFlash disk
  12. Homebrew AMD K6 system with 20 GB

So my network has up to 11 devices on it… Interesting!

Now for the rest of the machines:

  1. 40 GB iPod
  2. Nomad Jukebox with 20 GB
  3. Atari MegaSTE with 40 MB
  4. Atari 1040STFM with a floppy
  5. Atari 800XL with a floppy
  6. Oldest junkiest Dell 382SX-20 laptop with 20 MB
  7. AT&T PC6300 with 20 MB (my first PC)
  8. Broken Mac SE

There’s at least a terabyte and a half right there… Plus my collection of odd hard disks - just today I was marveling at the fact that I have 50 MB, 500 MB, 5 GB, 50 GB, and 500 GB hard disks!

Yeah, we’re nuts.
