Direct Attached StorageThe StorMaxT 6Gb SAS Direct-Attached-Storage (DAS) arrays are created to optimize sequential workloads in direct attached storage environments. It is worth pointing out that considering the fact that both SAN and NAS are network storage mediums, they both have some sort of network interface and IP addresses. If you never want to get into potentially immature stuff, all those NAS devices you happen to be searching at use MDADM and/or LVM to do their magic. Exclusive – Direct attached storage is paired straight with a single server, which means that the information it consists of cannot be shared with an additional server. In the light of this, some technique architects began to consider that networked storage was just also far away from the applications in the servers.

Western Digital has a starter NAS device Even although this only has a single really hard drive, it’s connected to the network, and is hence a NAS. Various systems can use the same DAS device, as extended as every single Pc or server has a separate connection to the storage device.

This form of storage is alternatively named captive storage, server attached storage or direct attached storage (DAS) as illustrated in Figure 1. Virtualised, multi-core servers fitted with terabyte-class flash memory do not have to have SAN or NAS disk. I undoubtedly would not put the boot drive as component of the RAID set for lots of causes, which includes if you want to wipe out your OS. But, major storage vendors have announced proprietary SANs that are nevertheless largely visions. As a outcome of weak storage standards, third-celebration DAS vendors such as EMC and Compaq Corporation, need to have to re-qualify their goods with each and every revision of a server’s operating method computer software. EMC’s Celerra gives a clustered network file … Read More
