Since the onset of Cloud computing and its inroads into infrastructure as a service, Virtualization has become peak
of importance in the field of abstraction and resource management. However, these additional layers of abstraction provided by
virtualization come at a trade-off between performance and cost in a cloud environment where everything is on a pay-per-use
basis. Containers which are perceived to be the future of virtualization are developed to address these issues. This study paper
scrutinizes the performance of a conventional virtual machine and contrasts them with the containers. We cover the critical
assessment of each parameter and its behavior when its subjected to various stress tests. We discuss the implementations and
their performance metrics to help us draw conclusions on which one is ideal to use for desired needs. After assessment of the
result and discussion of the limitations, we conclude with prospects for future research.

Pada pengalokasian media penyimpanan skala jaringan (network storage), diperlukan konsep yang baru untuk meningkatkan efektivitas komunikasi antar storage server dan client. Pada network storage konvensional, setiap node berkomunikasi dengan storage server menggunakan single file image yang terdapat pada server sehingga memungkinkan terjadinya kegagalan node tunggal (single point failure) yang mengakibatkan node server untuk layanan tertentu tidak dapat diakses sama sekali.
Proses transfer file pada server dapat dimodifikasi dengan mengubah mekanisme menjadi end user-initiator-storage server dengan konsep redundant server initiator sebagaimana konsep yang terdapat pada Storage Area Network. Dengan demikian hal tersebut membuat setiap initiator node yang ingin mengakses storage server harus memiliki file system yang sama dan mampu berkoordinasi satu sama lain. Untuk mengatasi hal tersebut diimplementasikan Cluster File System yang terpasang di setiap initiator node yang akan mengakses storage server. Mekanisme ini mendukung High Availability Clustering, setiap cluster node dapat mengakses dalam bentuk block-data pada storage server, dan file system pada setiap node merupakan Cluster File System yang dapat melakukan interkoneksi antar server dengan mekanisme fencing dan locking.
Pada Storage Area Network (SAN), Cluster File System yang diuji pada tugas akhir ini, memiliki failover delay yang bervariasi antara 6-12 detik yang berpotensi menjadikan proses transfer file menjadi terputus, memiliki kemampuan IOPS yang seragam dengan nilai bervariasi bergantung kepada spesifikasi hardware yang terdapat pada node server dan mengakibatkan penggunaan resource memory dan CPU yang lebih besar pada saat menggunakan block data dengan ukuran yang lebih kecil.

Storage Area Net work (SAN) switches and Storage Arrays have used for many t ime; they have become mo re ab ility of fault tolerance. These often involve some degree of redundancy. However, there are still issues that can occur and take some t ime t o resolve that problem co me in the Storage area network applicat ions. The number of Storage Protocols and Storage Interfaces rapidly increased in a Networking technology field, it avoids the Bottleneck of data centers. This paper focuses on few guidelines that may help to understand some of the design issues involved in SAN. Those Problems that are abstract and cannot solve on SAN infrastructure and application run on SAN can solve after understanding all the parameters. Fib re channels also, make so me concern that is not solvable and creates issues. This paper discusses some of the co mmon problem related to SAN to prevent the issues.

A program to develop planetary rover technology is underway at the Jet Propulsion Laboratory (JPL) under sponsorship of NASA. Developmental systems with the necessary sensing, computing, power, and mobility resources to demonstrate realistic forms of control for various missions have been developed, and initial testing has been completed. These testbed systems and the associated navigation techniques used are described. Particular emphasis is placed on three technologies: Computer-Aided Remote Driving (CARD), Semiautonomous Navigation (SAN), and behavior control. It is concluded that, through the development and evaluation of such technologies, research at JPL has expanded the set of viable planetary rover mission possibilities beyond the limits of remotely teleoperated systems such as Lunakhod. These are potentially applicable to exploration of all the solid planetary surfaces in the solar system, including Mars, Venus, and the moons of the gas giant planets

Abstract-Storage Area Networks (SANs) connect storage devices to servers over fast network interconnects. We consider the problem of optimal SAN configuration with the goal of retaining more security in meeting service level agreements (SLAs) on unexpected peaks. First, we give an algorithm for assigning storage devices to applications running on the SAN's hosts. This algorithm tries to balance the workload as evenly as possible over all storage devices. Our second algorithm takes these assignments and computes the interconnections (data paths) that are necessary to achieve the desired configuration while respecting redundancy (safety) requirements in the SLAs. Again, this algorithm tries to balance the workload of all connections and devices. Thus, our network configurations respect all SLAs and provide flexibility for future changes by avoiding bottlenecks on storage devices or switches. We also discuss integrating our solution with the open source SAN management software Aperi.

Policy-based management provides the ability to dynamically re-configure DiffServ networks such that desired quality of service (QoS) goals are achieved. This includes network provisioning decisions, performing admission control, and adapting bandwidth allocation dynamically. QoS management aims to satisfy the service level agreements (SLAs) contracted by the provider and therefore QoS policies are derived from SLA specifications and the provider's business goals. This policy refinement is usually ...

Today, access control security for storage area networks (zoning and masking) is implemented by mechanisms that are inherently insecure, and are tied to the physical network components. However, what we want to secure is at a higher logical level independent of the transport network; raising security to a logical level simplifies management, provides a more natural fit to a virtualized infrastructure, and enables a finer grained access control. In this paper, we describe the problems with existing access control security solutions, and present our approach which leverages the OSD (Object-based Storage Device) security model to provide a logical, cryptographically secured, in-band access control for today’s existing devices. We then show how this model can easily be integrated into existing systems and demonstrate that this in-band security mechanism has negligible performance impact while simplifying management, providing a clean match to compute virtualization and enabling fine gra...

Different studies show that programmers are more interested in finding definitions of functions and their uses than variables, statements, or arbitrary code fragments [30, 29, 31]. Therefore, programmers require support in finding relevant functions and determining how those functions are used. Unfortunately, existing code search engines do not provide enough of this support to developers, thus reducing the effectiveness of

Future missions to the moon, Mars, or other planetary surfaces will use planetary rovers for exploration or other tasks. Operation of these rovers as unmanned robotic vehicles with some form of remote or semi-autonomous control is desirable to reduce the cost and increase the capability and safety of many types of missions. However, the long time delays and relatively low bandwidths associated with radio communications between planets precludes a total “telepresence” approach to controlling the vehicle. A program to develop planetary rover technology has been initiated at the Jet Propulsion Laboratory (JPL) under sponsorship of the National Aeronautics and Space Administration (NASA). Developmental systems with the necessary sensing, computing, power, and mobility resources to demonstrate realistic forms of control for various missions have been developed and initial testing has been completed. These testbed systems, the associated navigation techniques currently used and planned for implementation, and long-term mission strategies employing them are described.

— Storage Area Networks (SAN’s) connect groups of storage devices to servers over fast interconnects using protocols like Fibre Channel or iSCSI, so that storage resources can be assigned to servers in a flexible and scalable way. An important challenge is controlling the complexity of the SAN configuration resulting from the high scalability of the network and the diversity and the interconnectivity of the devices. Policybased validation has been proposed earlier as a solution to this configuration problem. We propose a light-weight, SQL-based solution that uses existing well-known technologies to implement such a validation system. Our approach is based on a relational database which stores configuration data extracted from the system via a WBEM standard interface. In contrast to other approaches, we use SQL to define our policy rules as executable checks on these configuration data. Each rule is embedded in a test case, defined by an XML schema, which combines each check with an ...
