WARNING: There is a danger of a new battery exploding if it is incorrectly installed. Replace the battery only with the same or equivalent type recommended by the manufacturer. • Before you remove the system covers, perform the following steps in the sequence indicated: CAUTION: Except as expressly otherwise instructed in Dell documentation, only trained service technicians are authorized to remove the system cover and access any of the components inside the system. • You can also take the following steps to prevent damage from electrostatic discharge: • When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing material until you are ready to install the component. • Safety Instructions. • Overview The Dell PowerEdge RAID Controller (PERC) H700 and H800 family of cards: • Comply with Serial-attached SCSI (SAS) 2.0 providing up to 6 Gb/sec throughput. • Offer RAID control capabilities which include support for RAID levels 0, 1, 5, 6, 10, 50, and 60. • PCI Architecture • The PERC H700 and H800 cards support a PCI-E 2.0 x8 host interface. • The PERC H700 Modular cards support a PCI-E 2.0 x4 host interface. Operating System Support The PERC H700 and H800 cards support the following operating systems: •. • RAID Description RAID is a group of independent physical disks that provides high performance by increasing the number of disks used for saving and accessing data. A RAID disk subsystem offers the following benefits: • Improves I/O performance and data availability. • • RAID 50 is a combination of RAID 0 and RAID 5 where a RAID 0 array is striped across RAID 5 elements. RAID 50 requires at least six disks. • RAID 60 is a combination of RAID 0 and RAID 6 where a RAID 0 array is striped across RAID 6 elements. • Disk Mirroring With mirroring (used in RAID 1), data written to one disk is simultaneously written to another disk. If one disk fails, the contents of the other disk can be used to run the system and rebuild the failed physical disk. The primary advantage of disk mirroring is that it provides complete data redundancy. • The parity data is distributed across all the physical disks in the system. If a single physical disk fails, it can be rebuilt from the parity and the data on the remaining physical disks. RAID level 5 combines distributed parity with disk striping, as shown in Figure 2-3. • Storage Controller Features This section describes the features of the Dell PowerEdge RAID Controller (PERC) H700 and H800 cards such as the configuration options, disk array performance, RAID management utilities, and operating system software drivers. The PERC H700 and H800 family of controllers support Dell-qualified serial-attached SCSI (SAS) hard drives, SATA hard drives, and solid-state drives (SSDs).
