Dell issues a quarterly Server Update Utility (SUU) image which is used to update most firmware on PowerEdge servers (and some other Dell devices). As I use FreeBSD on my servers (which is not supported by Dell) I have to boot the Dell CDU CD to get a standalone Linux system suitable for launching SUU. Unfortunately, the SUU ISO image has become increasingly bloated over time, and is now too big to either burn to a double-layer DVD or upload to the 8GB vFlash card in the iDRAC. I suppose there’s some method for dealing with this if you’re running a Dell-supported operating system, but us FreeBSD users are left out. Here is a list of the last 4 quarters of SUU images, showing their sizes:<\/p>\n
The main part of the bloat is that the disc contains two versions of every update utility, one for Linux systems and one for Windows systems. Since the CDU provides a Linux system, we can delete all of the Windows files with no impact. I found it easiest to copy the entire SUU DVD to a scratch directory and then delete all the .exe files from the \\repository directory. There’s quite a few of them:<\/p>\n Directory of F:\\repository<\/p>\n [snip]<\/p>\n 400 File(s) 5,490,684,272 bytes01\/03\/2014 08:08 AM 7,986,208,768 SUU_740_Q42013_A00.ISO
