Core Services Cumulative Monthly Report, January 2007
Content/Web infrastructure
Primary objectives
Finish migration of DLPS web services to redundant networked
storage.
Dec: Marsh installed new storage on the Hatcher storage
server, and Snavely began batch synchronizing ETS and Image Services
content to it.
Replace web load-balancing system.
Increase scalability of ingest/processing/validation
processes with multiple front-end servers and/or SSI clustering.
Dec: Marsh and Snavely installed a new blade server chassis
that will be used to house multiple new servers, some of which will be
dedicated to content ingest and processing.
Apply automation and processes created for MDP to local
Digital Conversion workflows.
Migrate to new web statistics system.
Dec: Feeman began running the new stats system side-by-side
with the old starting in December and ported all non-title-level legacy
statistics from the old system to the new. Because title-level
statistics data were stored in the old system in a non-portable way,
and because the new system provides this information in the form of
COUNTER-style reports, title-level data was not ported but instead the
web
pages for title-level stats were harvested and will be made
available alongside the new system.
Dec: Feeman and Snavely developed an ordered list of bug
fixes to address and new features to be developed for the
authentication
and authorization management system.
Migrate Library Web Services to networked storage.
Continue work with ITCS on Shibboleth origin pilot.
Dec: Snavely contacted the people who expressed interest in
a Shibboleth pilot with ProQuest to determine their level of interest
and readiness, and received one or two enthusiastic responses; ProQuest
remains somewhat on the fence about implementation. Snavely sought
information on other service providers currently supporting Shibboleth
from Internet2 and consulted with Dennis and Folger on preferences.
Migrate all web service to Apache 2.
Storage
Primary Objectives
Migrate to new Pillar Axiom SAN in ALDC.
Dec: Marsh discovered and resolved a Solaris problem
relating to the mapping of SAN LUNs to OS devices.
Finish MDP RFP process and design and install sustainable,
large-scale storage solution for MDP project.
System administration
Primary Objectives
Finish transition of production services to TSM backup
service and upgrade existing backup system for development servers.
Dec: Snavely upgraded the current development backup server
to new hardware to increase performance and reliability.
Improve remote access capabilities to server resources using
serial console servers, network KVM (for blades), and VPN device(s).
Replace production and development servers as scheduled.
Standardize and document system administration processes.
Transition to Gigabit Ethernet service in room 10.
Secondary Objectives
Begin to develop centralized system administration mechanisms.
Transition to ITCS-supported DHCP.
Security
Primary Objectives
Complete security planning and perform TBD high-priority
tasks.
Dec: Marsh, Munce, Snavely, and Syrigos completed a first
draft of a security plan.
Secondary Objectives
Investigate virtual firewall service and request/implement as
appropriate.
Initiatives
Support integration/rearchitecture/massive scaling of
locally-developed content systems (Deep Blue, DLXS, MBooks).
Delve deeper into SSI clustering and server virtualization;
build proof-of-concept for virtual servers on an SSI cluster with an
eye toward centralized server resources for sharing among all LIT units.
Explore centralized storage for sharing among all LIT units.
Miscellaneous, routine, or unplanned
activity
Dec: Snavely met with CAS and ITCS staff to discuss the
dissolution of ITCS WATS and plans for transitioning application
support for a WATS-developed e-commerce system for ILLiad to Core
Services; Snavely discussed this work with Feeman, who began examining
the application and developing local documentation.
