It depends on what RAID level you are planning to use. One of the most common levels is RAID 1, data is written identically to multiple hard drives. This achieves redundancy in a RAID system. It creates a duplicate, a fail safe in case of a hard drive failure.
1 is for transmit and 1 is for redundancy
the swing bus is selected bus that has a fictitious generator with a p.u magntiude and phase angle equal zero ..in the power flow calculations ,The extra required energy or excess energy in the power system is managed by the generator of this bus.( supply/absorb p&Q) In order to achieve the balance between the generation ,the losses and the load ( Pgeneration = Pload + Plosses) solution of the power flow system is achieved when swing bus equal nearly zero
Mostly for small dc motor, 2core are used. earthing can be achieved by grounding the chassis.
No, as 100% efficiency is not possible.AnswerYes, it occurs at resonance. That is, when a circuit's inductive reactance is exactly equal to its capacitive reactance. This can be achieved by adjusting the frequency of the supply until resonance is achieved. Incidentally, power factor has nothing to do with 'efficiency'.
Including a series capacitor in the input and/or output circuit of the transistor. If the capacitor in the output circuit is omitted there will be a dc component in the output.
RAID 0.
A ______ uses block-level striping with parity data distributed across all member disks. It has achieved popularity because of its low cost of redundancy.
RAID 1
to connect multiple storage devices for redundancy or speed
Raid adapter
RAID level 1
If we need to install Windows Server 2008 R2 OS it does not requires any drivers. RAID is used for redundancy and Higher performance.
A Raid technology.
Reducing access and read time. Providing redundancy.
RAID (Redundant Array of Independent Disks) uses two or more drives in combination to create a fault-tolerant system. RAID configurations distribute data across multiple drives to improve performance, redundancy, or a combination of both.
A RAID 5 uses block -level striping with parity data distributed across all member disks. RAID 5 has achieved popularity due to its low cost of redundancy. This can be seen by comparing the number of drives needed to achieve a given capacity. RAID 1 or RAID 0+1, which yield redundancy, give only s / 2 storage capacity, where s is the sum of the capacities of n drives used. In RAID 5, the yield is . As an example, four 1TB drives can be made into a 2 TB redundant array under RAID 1 or RAID 1+0, but the same four drives can be used to build a 3 TB array under RAID 5. Although RAID 5 is commonly implemented in a disk controller, some with hardware support for parity calculations (hardware RAID cards) and some using the main system processor (motherboard based RAID controllers), it can also be done at the operating system level, e.g., using Windows Dynamic Disks or with mdam in Linux. A minimum of three disks is required for a complete RAID 5 configuration. In some implementations a degraded RAID 5 disk set can be made (three disk set of which only two are online), while mdadm supports a fully-functional (non-degraded) RAID 5 setup with two disks - which function as a slow RAID-1, but can be expanded with further volumes. In the example on the right, a read request for block A1 would be serviced by disk 0. A simultaneous read request for block B1 would have to wait, but a read request for B2 could be serviced concurrently by disk 1.
RAID 0 can be used to improve performance through concurrent access and/or create large logical disks out of multiple physical disks.
