Hardware

This server is a Dell PowerEdge 1420SC, with two 3.0GHz (2Mb Cache) Intel Xeon processors, 4Gb DDR2 RAM, and 838Gb of storage (via four 300Gb 10K RPM SCSI drives in a RAID Level 5 configuration). It was built on 11/29/2005, and it is connected to the internet through a SonicWALL TZ 100 firewall (installed on 9/13/2009), which in turn is connected to a Hatteras Networks HN402-CPi supporting 3M/3M SDSL service from Speakeasy.

Uniterruptible Power Supply is provided by an APC Smart-UPS 750 XL (SUA750XL) with five APC Smart-UPS Battery Packs (SUA24XLBP), installed on 12/17/2003.

Backup storage is provided by NAS boxes running various versions of Windows Server:

Except for a few scans, all of the pictures were taken with digital cameras. The Canon PowerShot S95 (acquired August, 2010) is a [need to fill in details] and the Canon 40D (acquired September, 2007) is a 10.1 megapixel Digital SLR that shoots 6.5 frames per second for bursts of 70 frames, and the

Previous cameras include the Canon PowerShot SD870 IS a ?.? mp etc., Canon PowerShot SD800 IS a 7.1 megapixel compact point-and-shoot camera that also records 30fps VGA (640x480) video, Canon 20D (acquired September, 2004) an 8.2 megapixel Digital SLR that shoots 5 frames per second for bursts of 27 frames, Canon D60 (acquired November, 2002), a 6.3 megapixel Digital SLR that shoots 3 frames per second for bursts of 8 frames, Casio QV3000 (acquired September, 2000) at 3.34 megapixels, Nikon Coolpix 900 (acquired July, 1999) at 2.1 megapixels, and Olympus D600-L (acquired December, 1997) at 1.3 megapixels.

ACDSee is used for picture viewing, and Paint Shop Pro for picture editing (cropping, resizing, redeye reduction). FrontPage and Notepad are used for editing web pages and managing files on the web site -- but most actual web page editing is done in raw HTML view (with the nice syntax coloring that FrontPage provides). The overall look and feel of the site is controlled with CSS, and the consistent navigation menus and footers are generated by server-side JScript code via ASP files. The multi-day "travel log" pages are generated using a "build" script (ASP JavaScript) that reads light-weight XML files.

History

This site was created in the fall of 1997 and hosted by a third party service.

When we acquired DSL in the summer of 1999 the site was moved to a single CPU Dell Precision 610 Workstation (built 6/4/1999) with a 500MHz Pentium III Xeon processor, 512Mb RAM, and 84Gb of storage (including a 70Gb SCSI II 10K RPM drive). This server ran Microsoft Windows NT Small Business Server 4.5 (NT 4.0 SP6 Server), including IIS 4.0 and Exchange Server 5.5.

In September, 2001, the site was redesigned to remove frames and provide a standard navigation menu at the top of each page. This was originally generated by client-side JScript code, but that proved incompatible with some versions of Netscape, and web crawlers could not find interior pages, so it was moved to server-side ASP (which required almost no code changes!)

In November, 2001, we switched to Seanet as our ISP (16 static IP addresses) but continuined using the Qwest DSL service with 1Mpbs download and 768Kbps upload speeds via a Cisco 678 DSL modem.
On 12/12/2005 we installed a SonicWALL T170 firewall.

On April 22, 2002, the site was moved to a new Dell PowerEdge 1400SC server, with two 1GHz Pentium III processors, 1Gb RAM, and 101Gb of storage (via four 36Gb 10,000RPM SCSI drives in a RAID Level 5 configuration). It was built on 3/26/2002. This server ran Windows Small Business Server 2000, including IIS 5.0, Exchange Server 2000, and ISA Server 2000.

On December 25, 2005, the site was moved to a new Dell PowerEdge 1420SC server, with two 3.0GHz (2Mb Cache) Intel Xeon processors, 4Gb DDR2 RAM, and 838Gb of storage (via four 300Gb Ultra 320 10K RPM SCSI drives in a RAID Level 5 configuration). It was built on 11/29/2005.

Desiring faster upload speeds (for website hosting) and tiring of the poor service provided by Seanet, on 9/13/2009 we moved to Speakeasy (32 static IP addresses) to get 3Mbps download/3Mbps upload speeds (they are reselling XO Communications SDSL service using the Hatteras technology). We also upgraded to a SonicWALL TZ 100 firewall.
