Current Status of Solaris Usage at CERN
• Second platform for LHC physics
– Mostly for validation purposes (numerical software)
• Total population of 663 Active nodes
– Figures from LanDB network database
• Around 300 on Solaris 8
• Rest: about a half running Solaris 2.6 and a half
on Solaris 7
– Problem: Most of these machines cannot upgrade OS
without hardware upgrade (disks and memory)

SUNINST0 Network Installation Server
• Jumpstart server
• Network configurations + responsible now fully
extracted from LANDB network database
– With single fetch procedure
• After router fix Sun DHCP server is stable
– On request of SM18 LHC Magnet Test had to
demonstrate boot of exotic devices (like data acquisition
devices) from it
• However, still working with CS group to replace
DHCP server with the one of CS
– SOAP interface to an Oracle DB will allow us to update
• Similar than the one in place for Print DNS hierarchy

CAE Server Upgrade (1)
• CAE - Electronic design cluster
• To serve the electronics design community
• New server: V480
– 4 x 900 MHz CPU
– 8 Gb SDRAM
– Gigabit ethernet
• A1000 RAID Disk box
– 436Gb with RAID 5 – space for users
• Had to coordinate IDPROM change with disk movement
– Hit technical and sociological problems
– IDPROM change: a need to keep old Cadence licenses on new
server - but SUN reluctant to do it for new HW models
– At the end provided ad hoc solution that does not support OBP
upgrade
• Found the hard way!
• And need OBP upgrade for A1000 support

CAE Server Upgrade (2)
• IDPROM problem not solved yet
– Considering to use other machine
• Cannot be too new (works on V220 or 280R)
• Also lots of A1000 RAID box problems
– RAID manager software has to be coordinated with
firmware level in the controller and OBP
• So lots of upgrades required before connecting old A1000s
to new server
– After first installation, additional A1000s are not seen
unless adding entries by hand to /kernel/drv/sd.conf
with the relevant SCSI ID

SUNDEV Technology Refresh
• A cluster for physics development
• 10 Sun Fire V210
– State of the art SPARC machines
– Thin Rack mountable servers
• 1 unit on 19” racks
• They all fit in a single CERN rack together with Gigabit
switch and Sun blade server
–
–
–
–
Dual 1GHz UltraSPARC-IIIi
2Gb memory
2 x 36GB Disk drives
4 x GIGABIT Ethernet on the motherboard
• They are being installed on Solaris 8.7.3 (latest
required for this hardware), later Solaris 9
• Performance improvement at least 120% over
the current SUNDEV machines

Implementation of EDG WP4 Quattor fabric
management on Solaris (1)
• We plan to use Quattor to manage all Solaris
systems
– From Solaris 9 onwards
• What does it mean for us?
– Central Configuration DataBase (CDB)
• Configuration information
• Software to be installed
– Both applications and system
• A cache manager provided for the client accessing the DB
– To avoid dependency on the DB server or on the network
• The configuration database is linked to the network
installation server
– The Jumpstart profile is generated from the database

Implementation of EDG WP4 Quattor fabric
management on Solaris (2)
– Node Configuration Manager (NCM)
• A la SUE
• For configuration “components”
– Simplified SUE features
• NCM components are simplified SUE features
• They have single action: “configure”
• They access Configuration DB through the cache manager
– SPMA software distributor (package level)
• Replaces ASIS software distribution (file level)
• For Linux it uses RPMs, for Solaris implemented with
Solaris PKG
• Allows to install packages from various SW repositories
• Several protocols supported: HTTP, file system (AFS), FTP,
etc.

Implementation of EDG WP4 Quattor fabric
management on Solaris (3)
• Still working on
– Creation of Solaris NCM Components from existing SUE
features (Juan Pelegrin)
– DB Access Control
• For delegation
– Behavior with “unmanaged” software

Solaris 9 Certification
• Validating Solaris 9 – running all SW on the new system
• Timescale for the end of 2003
– Refsol9 reference machine now available
• Not big changes in terms of Solaris, but new features:
– “Web Start Flash Archives”: system images for installation
• Nice for farms (but for same HW)
– Resource pools
• Guaranteed resources for an application on large shared systems
– Gnome 2.0 is the standard desktop environment
– We deliver Mozilla 1.4 (instead of Netscape recomm. by Sun)
– Sun ONE Studio 8 as default compiler
• Replacement of ASIS and SUE with Quattor
• More Open Source software packaged with the system
– Perl, Bash,…
– Some of these products supported on same basis as SUN
native ones
– Probably occasion to reduce the number of products
maintained by us

Sun Blade Server 1600 Installation and
Configuration
• Fully automated network installation (DHCP)
using Jumpstart from SUNINST0
– Initial configuration, installation & application software
• One private IP address for each System Controller
• One IP address for each Blade
• Ongoing Test of Web Start Flash Archives
– Quick replicate one Blade’s operating environment &
application software on other Blades intended
• Sun VTS (Validation Test Suite) online diagnostics
tool
– verifies configuration and functionality of hardware
controllers, devices and platforms

Sun N1 System Management Framework
• Sun N1 Provisioning server 3.0 Blade Edition
being tested
– Automates configuration and deployment different kinds
of servers
• Including specialized servers
• Assignment may vary according to a schedule or other
input – dynamic management of clusters
• To compare N1 with Quattor functionality
• Question: could N1 manage heterogeneous farms
out the Blade server scope?
