Page 8: Daily Use Tips
Daily Use Tips • Read this User’s Guide carefully. Follow the correct procedure when setting up the device. • Additional application software may have been included with your drive. Please review the documentation included with this software for information on the operation and support of this software. The documentation can usually be found in an electronic format on the installation CD. • Always operate your drive on a steady, level surface. Do not move the unit while it’s turned on. • Plug your drive into a grounded electrical outlet. The use of “ground-defeating” adapters will cause damage not covered by your warranty. -

Chapter 2 - Installation Connecting the SR4 requires an available power socket, and a host with an available PCI, PCI-X, or PCI Express slot. Your SR4 unit came with either a PCI-X eSATA RAID controller (PCI compatible) or a single lane PCI-Express eSATA RAID controller. Should you require a different or additional host bus adapter, contact your MicroNet Authorized Reseller for the best solution for your environment. - Page 11 2.3 Installing eSATA RAID host drivers The SR4 includes an eSATA RAID card. MicroNet provides drivers that support Windows 2000,2003,XP, and Vista, both 32bit and 64bit, along with Mac OS X 10.3.9 and newer. Drivers can be found on the included CD in the drivers directory, and the RAID utility is located in the Silicon Image RAID Utility directory.
- Page 12 Select “Search for a suitable driver for my device (recommended)” (Windows 2000) or “Install Software Automatically (Recommended)” (Window XP and 2003), then click Next. In the following window, check the “Search removable media” checkbox. If you do not have the driver CD, or downloaded drivers from MicroNet’s support site, check the “Include this location in the search” checkbox and navigate manually to the drivers location in order to install them.

2.3.2 MacOS X Installation ATTENTION! You must have administrator privileges on your system to install the drivers. Please consult your network administrator for more information. The Mac drivers are located on the CD in the following locations: PCI-X Models: /Drivers/eSATA RAID-PCIX/Mac OS X/SATARAID5.MPKG PCI-Express Models: /Drivers/eSATA RAID-PCIE/MAC OS X/SiI3132_1.1.9u_Sil_Pkg.pkg ATTENTION: As of this printing, The PCI Express Mac drivers available for the Silicon Image Sil3132 host controller support direct disk connection only. -

If you wish to reformat your SR4, be sure to create a copy of the files you wish to keep before reformatting. This step is not necessary for PCI-Express on Macintosh models.

3.1.2 Formatting the drive on Windows Hosts 1. Open the disk management console. A list of the attached drives and their respective volumes will appear. Each Volume set will appear as an individual disk in the management console. Upon the first time the SR4 is connected, a “Initialize and Convert Disk Wizard” should appear when the disk management console is run. You may use the Wizard to set up the volume, or follow the next steps for manual configuration. -

3.2 Replacing Drives 1. Save all your work and turn off your computer and SR4 unit. 2. Disconnect eSATA and power cords. 3. Remove the 3 thumb screws on the back of the unit. 4. Gently pull the top cover about 1/2” and remove from enclosure. -

Backing up your data is best defined by the keeping duplicate copies of your files on a separate storage device. It is always a good idea to keep important data in at least two different places. We recommend that you obtain and use a quality backup software application if the basic program that come with your operating system is not robust enough for your particular purposes. - Page 19 Chapter 4 - Understanding RAID The SR4 controller subsystem is a high-performance SATA2 drive bus disk array. When attached to the MicroNet SATA host bus RAID controller, the RAID subsystem can provide non-stop service with a high degree of fault tolerance through the use of RAID technology and advanced array management features.

Page 21: Appendix B- Raid Level Comparison Table
RAID 5 (Parity RAID) RAID 5 is sometimes called striping with parity at byte level. In RAID 5, the parity information is written to all of the drives in the subsystems rather than concentrated on a dedicated parity disk. If one drive in the system fails, the parity information can be used to reconstruct the data from that drive. -

4-Understanding RAID Hot Spare Drives A hot spare drive is an unused online available drive, which is ready for replacing a failed disk drive. In a RAID level 1, 10, 3, or 5 RAID set, any unused online available drive installed but not belonging to a RAID set can be defined as a hot spare drive. - Page 23 Q: Does the drive work with Norton Ghost or other disk cloning software? A: Yes. Many disk cloning software support SATA volumes. Consult your cloning software vendor; Fantom Drives does not provide any additional drivers. Q: Do you have “DOS driver” or a for the drive? A: No.

- Page 25 A-Getting Help Appendix A: Getting Help If you experience problems with your SR4, please contact your Authorized MicroNet Reseller for assistance. If the reseller is unable to resolve your issue, please contact MicroNet’s Help Desk for assistance. Please have the model, serial number, date of purchase, and reseller’s name available before making contact.
- Page 26 Appendix B: RAID Level Comparison Table RAID Description Min. Level Drives Also known as striping Data distributed across multiple drives in the array. There is no data protection Also known as mirroring All data replicated on N Separated disks. N is almost always 2. This is a high availability Solution, but due to the 100% duplica- tion, it is also a costly solution.
- Page 27 Digital’s IDE disk interface was standardized by ANSI to form the ATA specification using a 16-bit ISA bus. Cache cache is a fast-access memory bank that serves as an intermediate storage for data that is read from or written to secondary storage. Typically, high-speed caches are implemented in RAM, though they can also be implemented on disk when speed is not a critical requirement.
- Page 28 Hot Spare One or more disks in a RAID array may fail at any given time. In fact, all RAID types with the exception of RAID 0 provide methods to reconstruct the array in the event of such an occurrence.
- Page 29 C-Glossary Online Capacity Expansion The ability to add space to an existing RAID array within a session while preserving the RAID type and data within the array is known as online capacity expansion. The availability of this feature enables the user to add space to a RAID array as and when required without rebooting, thereby obviating the need for precise forecasts of capacity requirements for the future.
- Page 30 It provides the best data protection but can’t improve system performance. And storage space for the same data capacity should be double than in general cases. Hence storage cost doubles. The capacity of RAID 1 will be the size of the smaller HDD, so we suggest you connect HDDs of the same sizes to save HDD space.
- Page 31 Read Ahead Motivated by the principle of “spatial locality”, many RAID controllers read blocks of data from secondary storage ahead of time, i.e., before an application actually requests those blocks. The number of data blocks that are read ahead of time is typically governed by some heuristic that observes the pattern of requests.
- Page 32 Read Through Using this methodology, a read operation not only reads data from secondary storage into system memory but also places the data into the cache such that future need for the same data can be addressed expeditiously by directing a read operation for that data into the cache only.
- Page 33 Essentially write completion does not occur until the data is written to secondary storage. Thus the contents of the cache and the secondary storage are always consistent. The advantage is that the possibility of data corruption is greatly reduced.
