8456ch_Physical Planning.fm Draft Document for Review December 5, 2019 4:33 pm 7.3 Network connectivity planning 7.3.1 Hardware Management Console and network access Implementing the DS8900F requires consideration of the physical network connectivity of the  Hardware Management Console within your local area network. Consider the following network and communications issues when you plan the location and  interoperability of your storage systems: GLYPH<SM590000> HMC network access (one IP per HMC) GLYPH<SM590000> Remote support connection GLYPH<SM590000> SAN connectivity GLYPH<SM590000> IBM Security Key Lifecycle Manager connection if encryption, end point security or  transparent cloud tiering is activated or  GLYPH<SM590000> LDAP connection if LDAP is implemented For more information about physical network connectivity, see the  IBM DS8900 Introduction  and Planning Guide,  GC27-9560. The HMCs are the focal point for the configuration of Advanced Function management, and  maintenance for a DS8900F unit. Two internal Hardware Management Consoles are included  with every base frame. A dual Ethernet connection is available for client access. The two HMCs provides redundant  management access to enable continuous availability access for encryption key servers and  other advanced functions. The HMC can be connected to the client network for the following tasks: GLYPH<SM590000> Remote management of your system by using the DS CLI GLYPH<SM590000> Remote management by using the DS Storage Management GUI by opening a browser to  the network address of the HMC: https://< HMC IP address > To access the Hardware Management Consoles (HMC1/HMC2) over the network, provide the  following information: GLYPH<SM590000> Hardware Management Console: For each Hardware Management Console, determine  one TCP/IP address, host name, and domain name. GLYPH<SM590000> Domain name server (DNS) settings: If a DNS is to be implemented, ensure that it is  reachable to avoid contention or network timeout. GLYPH<SM590000> Gateway routing information: Supply the necessary routing information. Note:  Users also can control a second Ethernet adapter within the HMCs. This capability is  available only by RPQ.  For more information about HMC planning, see Chapter 8, “IBM DS8900F Management  Console planning and setup” on page 203. Important:  The DS8900F uses 172.16.y.z and 172.17.y.z private network addresses. If the  client network uses the same addresses, the IBM SSR can reconfigure the private  networks to use another address range option. 196  IBM DS8900F Architecture and Implementation
