---|---|---|
iSCSI target function | Supported | N/A |
iSCSI target function | Supported | TrueCopy® only |
iSCSI ports | 2 per interface board |
VSP Gx00 models: Maximum 32 per iSCSI system |
Connection methods | Direct and switch connections | |
Host connections | 255 (maximum per iSCSI port) | With Linux software initiator, the maximum number decreases. |
Path failover | HDLM1 | Supports Microsoft MPIO (Multi Path I/O) |
Link | 10 Gbps SFP+ | N/A |
Transfer speed | 10 Gbps | N/A |
Connector type | LC | N/A |
Cable | Optical OM3, OM2 MMF cable | N/A |
Network switch | L2 or L3 switch | Should comply with IEEE802.3ae |
Switch cascading | Maximum: 5 switches or fewer | Minimum number of cascading switches is recommended. |
MAC address | Per port (fixed value) | Factory setting: World Wide Unique value. Cannot be changed. |
Maximum transfer unit (MTU) | 1,500, 4,500, 9,000 bytes (Ethernet frame) | Jumbo frame, MTU size greater than 1500 |
Link aggregation | Not supported | N/A |
Tagged VLAN | Supported | N/A |
IPv4 | Supported | N/A |
IPv6 | Supported |
Note the following precautions:
|
Subnet mask | Supported | N/A |
Gateway address | Supported | N/A |
DHCP | N/A | N/A |
DNS | N/A | N/A |
Ping (ICMP ECHO) Transmit, Receive | Supported | N/A |
IPsec2 | N/A | N/A |
TCP port number | 3260 | Changeable among 1 to 65,535. Observe the following if changing values:
|
iSCSI name | Both iqn3 and eui4 types are supported | The unique iqn value is automatically set when a target is made. iSCSI name is configurable. |
Error recovery level | 0 (zero) | Error recovery by retrying from host. Does not support Level 1 and Level 2. |
Header digest | Supported | Detects header error or data error with iSCSI communication. The storage system follows the host's digest setting. If digest is enabled, the performance degrades. The amount of the degradation depends on factors such as host performance of host and transaction pattern. |
Data digest | Supported | |
Maximum iSCSI connections at one time | 255 per iSCSI port | N/A |
CHAP | Supported | Authentication: login request is sent properly from host to storage. CHAP is not supported during discovery session. |
Mutual (2-way) CHAP | Supported (not available if connected to Linux software initiator) | Authentication: login request is sent properly from host to storage. |
CHAP user registration | Max 512 users per iSCSI port | N/A |
iSNS | Supported | With iSNS (name service), a host can discover a target without knowing the target's IP address. |
