Large Linux Systems

• 4-way Pentium Pro SMP, sold by many Linux resellers.
• 2 GB real memory (per cpu), although Linux requires special adjustments for more than 1GB in an Intel x86 (Pentium) classs box due to Intel architecture limitations.
• Avalon Cluster (Beowulf architecture) ranks as the 114th most powerful supercomputer ever.
• 64 dual-cpu (for 128 processors total) 200MHz Pentium Pro's in a Beowulf cluster at the National Institues of Health
• Naegling has 88 cpu's (200MHz PentiumPro's) in a cluster. Combined storage is 11 GigaBytes real memory, 250 GigagBytes disk space.
• The original Beowulf has 32 CPU's in a cluster, passes one gigaflop in Nov 1996.
• 105 433MHz DEC Alpha systems in a 100Mbit ethernet network, used by Digital Domain to render special effects for the movie "Titanic"
• 54 GB filesystem (a 54 gig ext2fs filesystem was demoed on a RAID array at the 1996 Berlin Linux conference; contact Theodore Tso at MIT).
• 60 GB file system in an md RAID-0 striped across 7 disks, see ftp://ftp.gwdg.de
• 500 days continuous uptime
• Linux Uptime Survey provides an analysis of downtime reasons.
• 16-processor Sparc Supercomputer (Fujitsu)
• Jazznet 18-processor commidity cluster
• The Myrinet Gigabit Network card is being used to make & break LINPACK speed records on parallel clusters.
• 175 Gigabyte Database at DejaNews runs on Linux.

Largest Possible

• The ext2fssupports file systems up to 4 terabytes.
• The ext2fssupports filenames up to 255 characters, which can be increased to 1012 by recompiling the kernel appropriately.

Non-Linux Largest

• The largest (online, SQL) database in 1998 was from UPS, storing 16 terabytes of online data, running on DB2 on a S/390 mainframe.
• Petroleam exploration companies, Nasa, etc have large data repositories' but these are not kept live, on-line.
