exceed the highest industry standards, and the best data solution for small/medium business users. Caution Snapshot/rollback features need 512MB RAM or more. Please refer to RAM certification list in Appendix A for more detail. 1.2 Terminology The document uses the following terms: RAID RAID is the abbreviation of “Redundant Array of Independent Disks”. There are different RAID levels with different degree of the data protection, data availability, performance to ho

RAID width, RAID width, copy and row are used to describe one VG. RAID copy, E.g.: RAID row 1. One 4-disk RAID 0 volume: RAID width= 4; RAID (RAID cell in copy=1; RAID row=1. one row) 2. One 3-way mirroring volume: RAID width=1; RAID copy=3; RAID row=1. 3. One RAID 10 volume over 3 4-disk RAID 1 volume: RAID width=1; RAID copy=4; RAID row=3. WT Write-Through cache write policy. A caching technique in which the completion of a write request is not signaled until data is safely sto

Chapter 2 Getting started 2.1 Before starting Before starting, prepare the following items. ¨ Check the “Certification list” in Appendix A to confirm the hardware setting is fully supported. ¨ Read the latest release notes before upgrading. Release notes accompany with release firmware. ¨ A server with a NIC or iSCSI HBA. ¨ CAT 5e, or CAT 6 network cables for management port and iSCSI data ports. Recommend CAT 6 cables for best performance. ¨ Prepare storage system configuration

2.3 Identifying Parts of the subsystem The illustrations below identify the various features of the subsystem. Get yourself familiar with these terms as it will help you when you read further in the following sections. 2.3.1 Front View 1. HDD status Indicator Parts Function Green LED indicates power is on and hard drive status is good for HDD Status LEDs this slot. If hard drive defected in this slot or the hard drive is failure, the LED is orange. HDD ac

2.3.2 Rear View 1. Power Supply Alarm Reset button You can push the power supply reset button to stop the power supply buzzer alarm. 2. Uninterrupted Power Supply (UPS) Port (APC Smart UPS only) The subsystem may come with an optional UPS port allowing you to connect a APC Smart UPS device. Connect the cable from the UPS device to the UPS port located at the rear of the subsystem. This will automatically allow the subsystem to use the functions and features of the UPS.

2.4 Connecting iSCSI subsystem to Your Network To connect the iSCSI unit to the network, insert the cable that came with the unit into the network connection (LAN1) on the back of iSCSI unit. Insert the other end into a Gigabit BASE-T Ethernet connection on your network hub or switch. 2.5 Powering-on the Subsystem You should press the ON/OFF Power Supply Switch on the Switch. It will turn the iSCSI unit on and the Self-Test will be started automatically. 1. Plug in all the pow

2.6 Install Hard Drives This section describes the physical locations of the hard drives supported by the subsystem and gives instructions on installing a hard drive. The subsystem supports hot-swapping allowing you to install or replace a hard drive while the subsystem is running. 1. Pull out an empty disk tray. (You can install in any available slot.) 2. Take off the bracket before installing hard drive. 3. Place the hard drive in the disk tray. 4. Install the mounting screws on

2.7 iSCSI introduction iSCSI (Internet SCSI) is a protocol which encapsulates SCSI (Small Computer System Interface) commands and data in TCP/IP packets for linking storage devices with servers over common IP infrastructures. iSCSI provides high performance SANs over standard IP networks like LAN, WAN or the Internet. IP SANs are true SANs (Storage Area Networks) which allow few of servers to attach to an infinite number of storage volumes by using iSCSI over TCP/IP networks. IP SAN

The host side needs an iSCSI initiator. The initiator is a driver which handles the SCSI traffic over iSCSI. The initiator can be software or hardware (HBA). Please refer to the certification list of iSCSI HBA(s) in Appendix A. OS native initiators or other software initiators use the standard TCP/IP stack and Ethernet hardware, while iSCSI HBA(s) use their own iSCSI and TCP/IP stacks on board. Hardware iSCSI HBA(s) would provide its initiator tool. Please refer to the vendors’ HBA user

When DHCP service is not available, IS16GL use zero config (Zeroconf) to get an IP address. E.g., on LCM. IS16GL gets a DHCP address 192.168.10.50 from DHCP server. 192.168.10.50 IS16GL ← http://192.168.10.50 or https://192.168.10.50 (https: connection with encrypted Secure Sockets Layer (SSL). Please be aware of the https function is slower than http.)
