Metadata Server

CRUSH is one of the Ceph module,mainly solve the controllable, extensible, decentralized distribution of data copy. Ceph's biggest characteristics is a distributed metadata server is through CRUSH algorithm to allocate file storage location, its core is RADOS (Reliable, Autonomic Distributed Object Store), an object storage cluster, provide high availability of the object itself, error detection and repair.

Restful Web Service

Major Internet services are required to process a tremendous amount of data at real time. As we put these services under the magnifying glass, It's seen that distributed object storage systems play an important role at back-end in achieving this success. In this chapter, overall information of the current state-of –the-art storage systems are given which are used for reliable, high performance and scalable storage needs in data centers and cloud. Then, an experimental distributed object storage system (CADOS) is introduced for retrieving large data, such as hundreds of megabytes, efficiently through HTML5-enabled web browsers over big data – terabytes of data – in cloud infrastructure. The objective of the system is to minimize latency and propose a scalable storage system on the cloud using a thin RESTful web service and modern HTML5 capabilities.

This paper surveys different types of data storage architectures used in today’s world to store data of various types and presents an in-depth analysis of the use cases and drawbacks of the various storage architectures in different scenarios. We also examine the limitations of the traditional storage architectures in today’s world and also discuss the modern solutions to these problems. In this survey paper, we have provided a detailed comparison of three different storage architectures namely file storage, block storage, and object storage. This paper provides sufficient information to the reader to be able to choose among these architectures for storing their data as per the use case.

Tuntutan efisiensi dan High Availability (HA) pada sebuah virtual data center sebuah perusahaan sangatlah penting, salah satu produk solusi VMware yang menawarkan peningkatan HA adalah vSphere Metro Storage Cluster (vMSC) yang adalah sebuah solusi bersertifikasi vSphere yang menggabungkan replikasi dengan pengelompokan berbasis array. Selain itu terdapat solusi serupa yaitu Enhanced Linked Mode (ELM) yang mana digunakan untuk menghubungkan beberapa sistem Server vCenter bersama-sama dengan menggunakan satu atau beberapa Platform Services Controllers (PSC). Perbandingan keduanya dilakukan dengan menyesuaikan topologi yang adaDari perbandingan kedua solusi VMware tersebut, didapati keduanya mengalami down-time selama 2 detik ketika dilakukannya switchover. Keduanya pun meningkatkan dukungan HA yang baik namun secara konfigurasi ELM lebih unggul dikarenakan memiliki konfigurasi minimum. Hal tersebut menjadikan ELM lebih unggul karena mempermudah penembangan dalam menyesuaikan dengan topologi exsisting.
