execute the data transaction. Each CV can have different cache memory size by
user’s modification/setting. LUN (Logical Unit Number) is a unique identifier, in
which users can access through SCSI commands.
Chapter 2 Getting started
2.1 Before starting
Before starting, prepare the following items.
1. Check
“Certification list”
in Appendix A to confirm the hardware
setting is fully supported.
2. Read the latest release note before upgrading. Release note
accompany with release firmware.
3. A server with a NIC or iSCSI HBA.
4. CAT 5e, or CAT 6 network cables for management port and iSCSI data
ports. Recommend CAT 6 cables for best performance.
5. Prepare storage system configuration plan.
6. Management and iSCSI data ports network information. When using
static IP, please prepare static IP addresses, subnet mask, and default
gateway.
7. Gigabit LAN switches. (recommended) Or Gigabit LAN switches with
VLAN/LCAP. (optional)
8. CHAP security information, including CHAP username and secret.
(optional)
9. Setup the hardware connection before power on servers and i8500.
Connect console cable, management port cable, and iSCSI data port
cables in advance.
2.2 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 servers to
attach to an infinite number of storage volumes by using iSCSI over TCP/IP
networks. IP SANs can scale the storage capacity with any type and brand of
storage system. In addition, it can be used by any type of network (Ethernet, Fast
Ethernet, and Gigabit Ethernet) and combination of operating systems (Microsoft
Windows, Linux, Solaris, etc.) within the SAN network. IP-SANs also include
mechanisms for security, data replication, multi-path and high availability.
