....in disaster recovery. This paper presents the new algorithm and then compares it against various other multicopy and disaster recovery techniques. 1. Introduction In a sequence of recent papers, the concept of a single site RAID (Redundant Array of Inexpensive Disks) was introduced and developed [PATT88, PATT89, GIBS89]. Such disk systems have the desirable property that they survive disk crashes and require only one extra disk for each group of G disks. Hence, the space cost of high availability is only 100 percent, a modest amount compared to traditional schemes which mirror each physical disk at a space ....
....traditional multiple copy techniques such as surveyed in [BERN81] Moreover, RADDs are also candidate alternatives to high availability schemes such as hot standbys [GAWL87] or other techniques surveyed in [KIM84] This paper is structured as follows. Section 2 briefly reviews a Level 5 RAID from [PATT88], which is the idea we extend to a distributed environment. Then, in Section 3 we discuss our model of a distributed computing system and describe the basic structure of a RADD. Section 4 deals with performance and reliability issues of RADD as well as several other highavailability constructs, ....

....drives. When errors are discovered the redundant information can be used to restore the data and application programs can continue using the data with minimal interruption. Strategies based on this approach include synchronized disk interleaving [19] redundant array of inexpensive disks (RAID) [22], redundant array of distributed disks (RADD) 25] and parity striping of disk arrays [12] Examples of these approaches can be found in commercial systems today. For example, Tandem s NonStop SQL database machine uses mirrored disks, Teradata s DBC 1012 database machine employs interleaved ....

....we use the mean time to service loss (MTTSL) to quantify the fault resilience characteristics of the algorithms discussed in this paper. A common technique to protect against both data and service loss is to add redundancy to the system, either by mirroring data or adding parity information [4] [5]. There is a vast body of literature analyzing techniques in support of homogeneous disk subsystems [6] but very few are concerned with heterogeneous disk subsystems [7] 8] From a practical perspective, these techniques must be extended to support heterogeneous subsystems. This is due to the ....
....Reliability Modeling With the help of data replication or parity coding, the reliability of a disk array can be greatly improved. Several studies have quantified the reliability of homogeneous disk arrays in the context of continuous media servers with mirroring [17] parity coding schemes (RAID) [5], 18] 19] 6] 1] or a combination of both [20] The concepts of re liability or fault tolerance involve a large number of issues concerning software, hardware (mechanics and electronics) and environmental (e.g. power) failures. A large body of work already exists in the field of reliable ....

....these disks to deliver a highperformance and scalable storage service. PVFS [3] is one example of such file systems and it can achieve multiple GBytes sec I O throughputs [4] without any additional cost if the cluster is connected through Myrinet [5] or Gigabit Ethernet. However, like disk arrays [6], without any fault tolerance, these parallel storage systems are too unreliable to be useful since the failure rate of a cluster node, compounded by the failures of cluster hardware components, including CPU, disk, memory and network, and the software components, such as operating system and ....

....we get a starting point for the design of a general purpose parallel disks server based on the scheduling algorithms presented here. Section 8 summarizes the results and mentions some open questions. 1. 3 Related Work An automatic load balancing approach widely used in practice is striping [3, 4]. In our terminology that means a logical block size D times larger than the physical block size, where each logical block is dispersed over all disks. This works for scanning large amounts of consecutive data but is of little help for smaller access granularity. Without redundancy, worst case ....
