IRIS TECHNOLOGY

Storage

The storage platform for Video on Demand (VOD) is a Hitachi Thunder 9500v StorageArea Network (SAN). This fully redundant SAN is currently deployed as a 36Terabyte (TB) solution. IRIS Education support its clients and partners withtheir video (Windows Media, FLASH, Quicktime, MPEG2, etc.) and can serve as arepository for other data if desired.

The SAN is curved in to a sequential Logical Unit Numbers (LUN). This isdesigned to avoid any inadvertent disk signature thus eliminating the chance ofdisk corruption.

The Hitachi Thunder 9500v is a fiber channel connected array with multipleredundant drive systems, secondary power circuits, and an intelligentmanagement environment.

Server Operations

Our entire server farm is comprised of enterprise level, server classmachines in the Dell PowerEdge family of products. All servers sport multiplePentium Xeon processors. Deployments also include mirrored drives for furtherredundancy. Each server has dual network interfaces. The Clustered Server unitsalso have fiber channel host bus adapters.

Clustered Servers

Each Clustered pair has complete and exclusive ownership of their LogicalUnit Number (LUN) within the SAN. Two spare Clustered Server pairs areavailable for immediate deployment should a catastrophic issue arise taking outnot one but both units in the primary pair.

Our SQL services are also based upon a clustered pair. This insures that alldatabase services are as close to five 9s (less than 5 minutes down time peryear) operation as possible. SQL Enterprise is the standard at SCCtv.Integrating or servicing your data collection/management can be as basic or asrobust as your needs require. SCCtv access control and authentication servicesare SQL based.

NETWORK LOAD BALANCE (NLB) SERVERS

The SCCtv Network load Balance servers run our websites, the SCCtv domain,Windows Media Server operations and more. Current deployment included 6 unitsin place with 5 additional units available for deployment when project scalerequires such. The NLB operations are designed to scale to offer more than30,000 simultaneous Windows Media users leveraging in both our CommodityInternet and Internet2 connectivity.

ENCODER SERVERS

Encoder servers are deployed to encode live content (tape, satellite, cablefeeds) as well as content intended for VOD services. SCCtv uses the ViewCastOsprey 500 family of encoder/capture cards, developed in partnership withMicrosoft Windows Media group, for our encoding services.

BANDWIDTH

SCCtv, as a member of the Seattle Community College District, has access tothe bandwidth of the K20 Network. The K20 Network is a consortium of HigherEducation, K12 and other state agencies. Our aggregate bandwidth is 4 GB fullduplex to the Internet: 1.5 GB connectivity to the Commodity Internet, 2.5 GBconnectivity to the Internet 2 expanding aggregate bandwidth to 14 GB in an 18month time frame.
