Rados:a scalable, Reliable Storage Service for Petabyte-scale Storage ClustersThesis translationSummaryBlock and object-oriented storage architectures form a storage cluster that promotes extensibility. However, existing systems continue to use storage nodes as a passive device, although they have the ability to demonstrate intelligence and autonomy. We propose rados design and implementation, Rados is a reliable object-oriented service that can be ex
metadata server, an object storage server, and a monitor. Ceph fills in the gaps in distributed storage and it will be interesting to see how this open source product evolves in the future.ResourcesLearn
The Ceph creator's paper "Ceph:a Scalable, high-performance distributed File System" (PDF) and the PhD dissertation for Sage Weil, "ceph:reliable, Scal Able, and High-performance distributed Storage "(PDF), reveals the original idea behind Ceph.

Yte is a unit of measurement of computer information technology used to measure storage capacity and transmission capacity, with 1 bytes equal to 8-bit binary. At the moment we often calculate the smallest unit of storage space (in fact there is a smaller bit,1 byte=8 bit).However, from the hard disk or called storage space, we use the smallest unit is KB (kilobyte), the size of 2 10 bytes, and byte conversion is: 1kb=1024byteThe conversion of the future is basically based on 2 of the 10-time in

Byte is a unit of measurement used by Computer Information Technology to measure storage capacity and transmission capacity. one byte equals to eight-bit binary. Currently, we usually use the smallest unit of computing storage space (in fact, there are smaller bit, 1 byte = 8 bit ).
However, for hard disks or buckets, the minimum unit we use is KB (kilobyte), which is the 10th byte of 2. The conversion from byte to byte is 1
"), the computer's representation of many data are binary units, and 1 bits represents a binary digit, only 0 or 1;byte is the most commonly used in the computer unit, 8bit 1byte, Many places with 1b represent 1BIT,1B represent 1byte. 1 kilobyte equals 1000byte (10 bytes, or 1024byte, of 1kilobyte equals 2 for binary calculations in the computer). The conversion of some other units is described below:1 kilobyte KB = $ (10^3) byte1 megabyte MB = 1 (10^6) byte1 gigabyte GB = 1 (10^9) byte1
Storage capacity: The maximum number of data that can be stored on the storage device, typically in kilobytes (KB kilobyte), megabytes (MB megabyte), gigabytes (GB, gigabyte), Byte (TB, terabyte), and Pb (Petabyte), EB ( Exabyte), etc. to measure.
1kb=2 (b=1024b); The number in parentheses is the index of 2 (that is, how many times)
1mb=2 (a) kb=1024kb=2 (a) B;
1gb=2 (mb=1024mb=2) B.
1tb=2 (a) gb=1024gb
Bit bit (binary Digits): holds a binary number, which is 0 or 1, the smallest storage unit. byte byte:8 binary [bit (binary Digits)] bit is a byte (B), the most commonly used unit. 1B (byte- bit ) = 8bit (Binary Digits bit) is generally represented by B,KB,MB,GB,TB,PB,EB,ZB,YB,BB, and the relationship between them is: 1KB (kilobyte KB) = 1024B,1MB (megabyte megabyte abbreviated as "Mega") =1024KB,1GB (Gigabyte gigabyte, also known as "gigabit") =1024mb,1tb (
of binary numbers, which is generally an 8-bit binary number as a numerical unit in a computer. For example, an ascii code is a byte. The conversion of such units is:1 gib (TB, terabyte) = 1024 gib (40 to the power of 2)(1 TB = 1024 GB)1 gib (GB, gigabyte) = 1024 MB (2 to the power of 30 bytes)(1 GB = 1024 MB)1 MB (megabyte) = 1024 kilobytes (20 to the power of 2)(1 MB = 1024kb)1024 bytes (kb, kilobyte) = bytes (10 to the power of 2) (1kb = 1024b)1 b

The amount of memory occupied by the data can be calculated by multip
