RAID 5E, RAID 5EE, and RAID 6E (with the added E standing for Enhanced) generally refer to variants of RAID 5 or 6 with an integrated hot-spare drive, where the spare drive is an active part of the block rotation scheme. This spreads I/O across all drives, including the spare, thus reducing the load on each drive, increasing performance.
The Mercedes-Benz OM612 engine is a straight-5 diesel engine produced by Daimler AG, today Mercedes-Benz. It was introduced in 1999 for the 2000 model year in a 170 PS (125 kW; 168 hp) version in the W210 E-Class, W211 E-Class, W163 ML-Class, W203 C-Class and W209 CLK-Class in 2000. Also used in the Austrian built Jeep WG Grand Cherokee (ENF in ...
2006 LL8 (Vortec 4200) engine in 2006 Chevrolet TrailBlazer. The LL8 (or Vortec 4200), is a straight-6 gasoline engine produced from 2002 to 2009. It was the first Atlas engine, and was introduced in 2002 for the Chevrolet TrailBlazer, GMC Envoy, and Oldsmobile Bravada. The engine was also used in the Buick Rainier, Saab 9-7X, and Isuzu Ascender.
A flawed RAID 5/6 also exists, but can result in data loss.) [10] For RAID 1, the devices must have complementary sizes. For example, a filesystem spanning two 500 GB devices and one 1 TB device could provide RAID1 for all data, while a filesystem spanning a 1 TB device and a single 500 GB device could only provide RAID1 for 500 GB of data.
As a RAID 0 array striped across RAID 5 elements, minimal RAID 50 configuration requires six drives. On the right is an example where three collections of 120 GB RAID 5s are striped together to make 720 GB of total storage space. One drive from each of the RAID 5 sets could fail without loss of data; for example, a RAID 50 configuration ...
Those RAID systems made their way to the consumer market, for users wanting the fault-tolerance of RAID without investing in expensive SCSI drives. Fast consumer drives make it possible to build RAID systems at lower cost than with SCSI, but most ATA RAID controllers lack a dedicated buffer or high-performance XOR hardware for parity calculation.
Cylinder, head, and sector of a hard drive. Cylinder-head-sector (CHS) is an early method for giving addresses to each physical block of data on a hard disk drive. It is a 3D-coordinate system made out of a vertical coordinate head, a horizontal (or radial) coordinate cylinder, and an angular coordinate sector. Head selects a circular surface ...
The increased displacement gave improved vehicle performance and lower manufacturing cost, for it was achieved with the tall RG block also used with the 225 engine by installing a crankshaft with 3.64 in (92.5 mm) stroke and connecting rods 7.006 in (178.0 mm) long, for an actual displacement of 198.3 cu in (3.2 L).
