Storage Policies Before you use the LaCie Two Big Manager to configure the Storage Appliance, take a minute to study the following terms. The terms represent The LaCie Two Big configuration options or storage policies for mapping the physical to the virtual drives. You’ll choose from these policies during the configuration process. Your choice is important and impacts how best you can use the Storage Appliance. IMpOrTANT INfO: Your LaCie Two Big comes preconfigured in fAST (rAID 0) mode. For more informa- tion about RAID levels, see chapter 7. Understanding RAID and Two Big Storage Policies. fAST A storage policy configuration in which I/O processing is balanced evenly to all disks in a method known as strip- ing, equivalent to RAID 0. Fast offers the best performance in terms of speed but no redundancy of data. Striping increases storage operation speed by using several disk drives in parallel. Each portion of data is divided into segments which are written to different disks simultaneously. Striping provides improved performance but does not enhance reliability because there is no way to retrieve or reconstruct data stored on a failed drive.

LaCie Two Big Hard Drive Tech Tips User Manual page 6. Tech Tips 6.1. Available Storage Capacity A gigabyte (GB) means 1,000,000,000 bytes. In order to utilize a hard disk drive, it has to be formatted first. Formatting a disk consists of the following: the operating system erases all of the bookkeeping information on the disk, tests the disk to make sure that all of the sectors are reliable, marks bad sectors (i.e., those that are scratched) and creates internal address tables that it later uses to locate information. Once formatted, the actual available storage capacity varies, depending on operating environment, and is generally about 5 to 10% less than the non- formatted capacity. TECHNICAl NOTE: Storage capacity of an array depends on the RAID level. The capacity of a RAID array can be found by multiplying the capacity of the drives in the array by the number of non-redundant drives. -

Page 30: File System Formats - Windows Users
LaCie Two Big Hard Drive Tech Tips User Manual page 0 6.2.2. File System Formats – Windows Users Since the LaCie Two Big comes preformatted in HFS+, the Mac Operating system, you will need to reformat your drive in FAT 32 or NTFS. The following information will hopefully make choosing one or the other a little easier. fAT 32 FAT is an acronym for File Allocation Table, which dates back to the beginnings of DOS programming. Originally, FAT was only 16 bits, but after the second release of Windows 95 it was upgraded to 32 bits, hence the name FAT 32. In theory, FAT 32 volume sizes can range from less than 1MB all the way to 2TB. It is the native file system of Windows 98 and Windows Me, and is supported by Windows 2000 and XP. When FAT 32 is used with Windows 2000 and XP, though, volume size is limited to 32GB (by the Windows partition utility, i.e. Disk Manager), and the individual file size is limited to 4GB. NTfS This acronym stands for New Technology Filing System, and it is the native file system for Windows NT, Windows 2000 and XP. NTFS offers several features that are not available with FAT 32; i.e. file compression, encryption, permissions, and audit- ing, as well as the ability to mirror drives and RAID 5 capabilities. The minimum supported volume size for NTFS is 10MB, with a maximum of 2TB, with no limit to file size. Volumes created in NTFS can only be directly accessed (not through shares) by Windows NT, Windows 2000 and XP, without resorting to help from third-party products. Guidelines for Choosing FAT 32 Or NTFS Use fAT 32 if: • You want to access your data on any Operating System - FAT 32 is compatible with Windows 98 SE, Me, 2000, XP, NT,... -
Page 31: Serial Ata Ii Questions And Answers
LaCie Two Big Hard Drive Tech Tips User Manual page 6.3. Serial ATA II Questions and Answers What is Serial ATA II? The Serial Advanced Technology Attachment (ATA) II marks the latest rung on the evolutionary ladder of SATA technology. SATA II can deliver data at 300MB/s, twice as fast as its SATA predecessor and more than twice as fast as the Parallel ATA/ IDE (Integrated Drive Electronics) interface, which has long been used to connect peripheral devices to the computer. Initial Serial ATA technology removed the performance bottleneck of the Parallel ATA specification, and follows a clearly defined road-map to greater and greater data transfer rates and feature improvements. Deriving its name from the way that it transmits signals, in a single stream, or serially, Serial ATA operates in a point-to- point topology. This connectivity methodology delivers the entire available interface bandwidth to each device, allowing each device to operate at its maximum throughput, and provides direct communication between the device and the system at any time, reducing arbitration delays associated with shared bus topologies. What are the key differences between Serial ATA and Serial ATA II technology? Serial ATA (SATA) II allows twice the transfer speed of Serial ATA and can support what’s called a port multiplier. With a... - Page 32 LaCie Two Big Hard Drive Tech Tips User Manual page own drive head’s angular and rotational position, the drive selects a data transfer from the queue that will minimize both its seek and rotational latencies. • Simplified structure: Serial ATA utilizes a more efficient signaling voltage (250mV vs. 5V for Parallel ATA), and much smaller, thinner and compact cables and connectors. Due to the simplified cabling (the reduction in the number of pins and wires), the number of fault possibilities decreases. • Seamless integration: Serial ATA maintains register and software compatibility with Parallel ATA, and should be transpar- ent to both the BIOS and operating system. Simply add more Serial ATA links to increase the number of connectivity points in your system. What are the ideal uses of Serial ATA? Although the specification supports all ATA and ATAPI devices (i.e. CD, DVD, tape drives, etc.), and delivers superior per- formance than both Hi-Speed USB 2.0 and FireWire/IEEE 1394, external Serial ATA connectors are intended for storage devices. Serial ATA works best in storage environments that require high data throughput to deliver large files quickly and efficiently, maximizing the storage systems utilization and enhancing overall productivity. Due to its performance, reliability, scalability and cost-effectiveness, Serial ATA can be implemented in a wide-range of set- tings, from desktop usage to network storage applications.

Data blocks are duplicated, Using two controllers, or duplexing, can speed the data I/O rate or mirrored in each pair of by writing to both drives at the same time. When using just a single disks in the array. controller operations are slowed because data is written first to the data drive and then to the mirrored drive. CONTROLLER The storage capacity of a two-disk RAID 1 array is equal to the storage capacity of a single disk because the same data is dupli- cated on both disks. However, the 100 percent redundancy of data does not require a rebuild in the case of a drive failure. In that case, data can be copied to a replacement disk. -
