## CAS System Status

-  D0mino upgrade in place in FCC1
-  Will add:
- 128 CPUs		(currently 48 -> 176)
- 64 GB Memory	(currently 12 -> 76)
- 21 TB Disk		(currently 7 -> 28)
-  Will be reconfigured into single unit Tuesday, Feb 13th.
-  Work will begin at 7:00AM, will continue throughout the day, possibly going past 5:00PM.
-  Plan accordingly

## Farm Systems

-  100 Dual processor nodes in place
- 50 nodes 2x500 MHz,   512MB memory, 50GB disk
- 50 nodes 2x750 MHz,    1.0GB memory, 60GB disk
-  Will hold 10 nodes for fast turn around D0reco certification
-  Will hold 10 nodes for farm testing
-  If running at 20Hz, have ~8sec/event processing time
- ~d0lxbld4 equivalent times
-  Farms will be down Feb 8th for OS upgrade of I/O node

## Database Server

-  Production database on 6 processor SUN system
- ~300 GB disk space for production database
- Should be adequate for ~8 months full scale running
-  200 Tape library running Legato in place for backups
-  Database systems will be down Feb 13th for Oracle upgrade.

## Robotics and Tape Storage

-  Robot operation has stabilized
- Have regular meetings with ADIC to examine any maintenance issues
- Maximum throughput to date: ~5TB in one day
- Enstore will be down Feb 13th
-  Tape drive situation still unclear
- Have had inconsistent results with Mammoth-2 drives
- Exabyte delivered set of “golden” drives for testing two weeks ago
- Have put ~11TB through drives in testing
-  One significant event every ~2TB (requires intervention)
-  One tape damaged (of ~200)
- Will begin run with backup copy of data on disk (until ~June)
- Will maintain secondary copy of raw data on tape
-  Exact configuration of drives yet to be determined (LTO?, 9940?)
- Goal to have final configuration by time physics data begins

## Desktop Hardware

-  CD is evaluating desktop hardware for compatibility with FRHL.
-  If interest from user community is sufficient, lab would consider stocking standard desktops for purchase by users similar to way CERN does.
- Need feedback from users:
- Would you buy desktop from stock if it was available and certified to run FRHL?
- How many might you be interested in within the next 6-12 months?
- If interested, send mail to diesburg, wyatt, or schellman.
- Downside: not the absolutely latest and greatest hardware
- Overhead issues unknown

## Security Issues

-  Most systems fully Kerberized
- Farms - Fully Kerberized
- Database Server - Fully Kerberized
- D0mino - Fully Kerberized
- Servers - Almost,  still some issues to resolve for off-site CVS access

## Security Issues

-  Like work related injuries, most security incidents are preventable.
-  If you are managing your own desktop or those of others, DILIGENCE on your part is required.
- If you are running Win95/98 on your desktop, upgrade to NT
- Make sure you have anti-virus software installed
- No open shares on desktop or laptops
- Keep abreast of security warnings in mailing lists and D0news
-  Don’t just read them, TAKE ACTION!
- Don’t open executable attachments unless you have a good idea what is in them, even if they come from a reputable source.
- Laptops need special care
- Be sure you have registered your laptop with Network group!

## Security Issues

-  Security incidents involving D0 people or machines for period Jan 1st to Feb 1st:
- 26 e-mail viruses intercepted by mail server
- 16 network assaults on D0 subnet
- 8 Windows systems infected with viruses, 700+ files infected
- 1 Linux system hacked
- 2 Napster servers shutdown
- 3 FIREs
