Chapter 3 Connections
3.1 Host Connections
• Virtual Local Area Network (VLAN tagging)
The VLAN tagging function is supported. A tag (VLAN ID) can be used for each port.
When the ETERNUS DX Disk storage system is connected to multiple servers, use a LAN switch that has
the VLAN function and allocate a separate segment to each server so that security can be maintained.
• Jumbo Frame
Enabling Jumbo Frame makes data transfer more efficient by increasing the amount of data that can be
transferred for each Frame.
Table 3.1
Enabled
Disabled
• Confirm that the connected device supports Jumbo Frame before enabling Jumbo Frame.
• Server-side CPU load can be reduced by using Jumbo Frame. However, I/O performance may be
reduced by 10% to 30%.
• Security Architecture for Internet Protocol (IPsec)
The IPsec function is not supported. Connect the server using a LAN switch that has the IPsec function as
required.
• Internet Protocol
IPv4 and IPv6 are supported.
IPv6 is supported in firmware version V10L35 or later.
■ FCoE
Fabric is supported as a connection topology. The maximum transfer speed is 10Gbit/s. When using an FCoE
interface, connect the ETERNUS DX Disk storage system to the FCoE switch. Direct connections to servers are
not supported.
• Perform zoning settings for FCoE switches.
• When an FCoE interface is used for the HBA of the server, use FCoE for the host interface of the ETERNUS
DX Disk storage system.
