TUCSAN ist das Speichernetzwerk (Storage Area Network) der TU Chemnitz. Es realisiert auf einem Midrange-Speichersystem und elf Raid-Systemen eine direkt nutzbare Gesamtspeicherkapazität von 83 TB. Für automatisierte Datensicherungen und Redundanz stehen weitere 104 TB zur Verfügung. Der Vortrag stellt die eingesetzte Technik und die Sturktur von TUCSAN vor. Weiterhin werden die damit realisierten Dienste präsentiert und es wird ein Ausblick auf künftige Vorhaben gegeben. Der Vortrag wurde am 10.

International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / A traditional Front-end Processor (FEP) with local RAID storage can limit the operational throughput of a high-rate telemetry ground station. The Front-end processor must perform pass processing (frame synchronization, decoding, routing, and storage), post-pass processing (level-zero processing), and tape archiving. A typical fifteen minute high-rate satellite pass can produce data files of 10 to 20 GB. The FEP may require up to 2 hours to perform the post-pass processing and tape archiving functions for these size files. During this time, it is not available to support real-time pass operations. Honeywell faced this problem in the design of the data management system for the DataLynx ä* ground stations. Avtec Systems, Inc. and Honeywell worked together to develop a data management system that utilizes a Storage Area Network (SAN) in conjunction with multiple High-speed Front-end Processors (HSFEP) for Pass Processing (PFEP), multiple HSFEPs for Post-pass Processing (PPFEP), and a dedicated Tape Archive server. A SAN consists of a high-capacity, high-bandwidth shared RAID that is connected to multiple nodes using 1 Gbps Fibre Channel interfaces. All of the HSFEPs as well as the Tape Archive server have direct access to the shared RAID via a Fibre Channel network. The SAN supports simultaneous read/write transfers between the nodes at aggregate rates up to 120 Mbytes/sec. With the Storage Area Network approach, the High-Speed Front-end Processors can quickly transfer the data captured during a pass to the shared RAID for post-processing and tape archiving so that they are available to support another satellite pass. This paper will discuss the architecture of the Storage Area Network and how it optimizes ground station data management in a high-rate environment.

The storage vendors have their own standards for the management of their storage resources but it creates interoperability issues on different storage products. With the recent advent of the new protocol named Storage Management Initiative-Specification (SMI-S), the Storage Networking Industry Association (SNIA) has taken a major step in order to make the storage management more effective and organized. SMI-S has replaced its predecessor Storage Network Management Protocol (SNMP) and it has been categorized as an ISO standard. The main objective of the SMI-S is to provide interoperability management of the heterogeneous storage vendor systems by unifying the Storage Area Network (SAN) management, hence making the dreams of the network managers come true. SMI-S is a guide to build systems using modules that ‘plug’ together. SMI-S compliant storage modules that use CIM ‘language’ and adhere to CIM schema interoperate in a system regardless of which vendor built them. SMI-S is object-oriented, any physical or abstract storage-related elements can be defined as a CIM object. SMI-S can unify the SAN management systems and it works well with the heterogeneous storage environment. SMI-S has offered a cross-platform, cross-vendor storage resource management. This thesis work discusses the use of SMI-S at Compuverde which is a storage solution provider, located in the heart of the Karlskrona, the southeastern part of Sweden. Compuverde was founded by Stefan Bernbo in Karlskrona,Sweden. Just like all others leading storage providers, Compuverde has also decided to deploy the Storage Management Initiative-Specification (SMI-S) to manage their Storage Area Network (SAN) and to achieve interoperability. This work was done to help Compuverde to deploy the SMI-S protocol for the management of the Storage Area Network (SAN) which, among many of its features, would create alerts/traps in case of a disk failure in the SAN. In this way, they would be able to keep the data of their clients, safe and secure and keep their reputation for being reliable in the storage industry. Since Compuverde regularly use Microsoft Windows and Microsoft have started to support SMI-S for storage provisioning in System Center 2012 Virtual Machine Manager (SCVMM), this work was done using the SCVMM 2012 and the Windows Server 2012.The SMI-S provider which was used for this work was QNAP TS- 469 Pro. / 0764354242
