30th Annual Report 2017-18

154 simulator, (3) Design document for the interface between TCS and the telescope Enclosure, and (4)Aplan for all the subsequent project phases. Based on the successful completion of first phase, IUCAA on behalf of India-TMT contractually engaged Honeywell for the full Preliminary Design (PD) phase. The work on PD phase started in July 2017. It consists of the following key aspects of the design: (1) System engineering, (2) Design and prototyping of various subsystem interfaces, (3) Safety, (4) Reliability, (5) Operations, (6) Management, and (7)Acomplete plan for the Final Design phase. The objective of PD phase is to deliver a sufficiently detailed design to demonstrate that (i) design and interface requirements are met, (ii) all significant design choices are met, (iii) enabling technologies are developed, and (iv) major risks are retired. The work is progressing well and is scheduled to be completed in mid-2019 with a detailed review at TMT Project Office, Pasadena. The successful completion of this phase is a crucial milestone towards delivering the full preliminary design of the TCS, which is arguably the most complex software systemof the telescope. ComputingCentre The IUCAA Computing Centre continues to offer state-of-the-art computing hardware and technology rich mobile work space for IUCAAmembers, associates and visitors. It also extends an array of specialized High Performance Computing (HPC) environments to the academic community for their research. The hardware and devices currently managed by the computing facility include 315 servers and desktops, 72 laptop computers, 83 printers and scanners, two large High Performance Computing systems and over a PetaByte of storage, in addition to diverse equipments deployed for an extensive, high throughput wired and wireless campus-wide network. The number of registered WiFi devices is over 800. IUCAAprovides e-mail services to its members and associates, and the total number of accounts being nearly 500. IUCAAhas its own registered domain name as “iucaa.in ”. The WAN services are provided by the National Knowledge Network on a 1 Gbps fibre connectivity, with a fallback arrangement on a 50Mbps line fromTATAVSNL. In the year 2017- 2018, emphasis was given to implementation of: 1) Purpose built backup appliance (PBBA), which was arrived on March 24, 2017, in the form of Dell-EMC Data-Domain 6800, the back-end backup storage and Net-worker (backup management software). The PBBA has been configured to backup various important physical and virtual servers/services like IUCAAweb server, email server, VMware clients, LIGO web server and user filesystems. 2) The file server NetApp FAS 2020 was implemented inApril 2011. The old file server, i.e., NetApp FAS 2020 was replaced by new NetApp FAS 8020with the higher capacity, better redundency and lowpower, cooling requirement. 3) PaperCut, a print, scan and copy management software has been setup. This allows to assign user based print quota, secure (pin based) printing, and print tracking. New Multi-Function Printers (MFP) have been procured and configured through PaperCut. The use of PaperCut has resulted in 30%paper saving in a year. 4) Effort has continued to improve the WiFi connectivity within the IUCAA campus. In November 2017, 9 outdoor Access Points (Aps) ZF7762 were replaced with T301s APs and T610s. Also 25 indoor Access Points ZF 7343 were replaced with R510.
