How to build a NPIV based infrastructure cloud

Cloud Computing is a comprehensive solution to delivering IT in a service format. It has the characteristics of on demand, for the enterprise to save the early hardware and service costs, but also can greatly improve the resources utilization of enterprises. At the service level, cloud computing can be divided into http://www.aliyun.com/zixun/aggregation/13748.html "> Infrastructure Cloud (IaaS), Platform-Service (PaaS), and software-as-service (SaaS).

NPIV (N_port ID virtualization) is an industry standard that provides a good technical solution for the infrastructure cloud by providing multiple hosts sharing the virtualization implementation of the same fibre channel through a virtual HBA card.

Based on the IBM Power SYSTESM product, this article demonstrates how to build an infrastructure cloud environment based on the NPIV environment and show readers how to implement the infrastructure cloud using the IBM Cloud Products SmartCloud Entry.

NPIV Introduction

N_port ID Virtualization (NPIV) is a virtualization technology that is applied to storage area network (SAN) Fibre Channel. SAN network mainly includes servers, fiber-optic switches, storage devices, etc., communication between the devices in the network, through the corresponding ports, in the NPIV environment, need to understand several basic concepts.

N_port is a port on a SAN network that corresponds to a server or storage node, such as a port on a server HBA card, and a destination port for a storage device.

F_port the ports in the SAN network that correspond to the fibre switches. The F_port on the switch is connected to the N_port to form the corresponding communication link.

E_port is the interface between the corresponding switch and the switch.

NPIV technology enables the physical single n_port to be virtualized out of multiple ports with a unique N_port ID (also known as Fiber Channel ID, fcid) for each port. This ID is a 24-bit address, and each N_port ID is mapped to a world Wide Port Name (WWPN). Simply put, the HBA on the server accesses the FCID via the Fibre Channel network, then registers the virtual WWPN into the network to obtain the fcid of these virtual WWPN, so that the WWPN of the SAN can be divided and the storage LUNs are carried out according to the physical Zone operation. Mappings.

Advantages of NPIV:

1 compared with traditional VSCSI mode, the Zone partition of SAN network is realized, and the storage LUN mapping is more convenient and safe. Traditionally, a LUN mapped on a store is visible to all virtual machines on all physical machines, because a WWPN on the physical machine is in a Zone, and NPIV can implement a corresponding WWPN for each virtual machine, so that only the corresponding LUNs are visible.

2 The requirement of physical HBA card is reduced by virtualization N_port, and the resource utilization is improved.

NPIV Cloud Environment

Environmental preparedness

This article will highlight the construction of NPIV cloud environment, so we list some prerequisites, their specific implementation process is no longer described, if necessary, can refer to relevant materials or articles.

Hardware preparation: One Power machine (VIOS2.2.1.0 installed), Hardware Management console (HMC) machine, ibm_2498_b24 SAN switch one, 8GB fiber card, storage V7000; Software Preparation: Install the HMC and upgrade to v7r7.4.0.0; Configure V7000 Management system VIOS and upgrade to 2.2.1.3; install smiagent 120.11.0;

Hardware check

Check if the fibre switch used supports NPIV features

Log on to the IBM_2498_B24 fibre switch and execute the following command:

ibm_2498_b24:root> version kernel:2.6.14.2 Fabric os:v6.3.0d Made on:mon Mar 17:00:15 flash:mon June 21 15:13:19 bootprom:1.0.9

Its Fabric OS version (v6.3.0 D) is higher than 5.3.0 to indicate that the IBM_2498_B24 fibre switch version meets the requirements.

ibm_2498_b24:root> portcfgshow Ports of Slot 0 0 1 2 3 4 5 6 7 8 9-----------------+--+--+--+--+----+--+ --+--+----+--+--+--+----+--+--+--Speed an A an A and an a an A...

The above results indicate that the NPIV function has been opened. If necessary, you can execute the command portcfgnpivport <port_num>, 1 to open the NPIV function for the corresponding port number.

Check to see if the HBA card supports NPIV features

Using the user Pamdin login VIOS, execute the command:

$ lsnports name Physloc fabric tports aports Swwpns Awwpns fcs0 u78aa.001.wzsgcf1-p1-c4-t1 0 2048 2048 U78AA.001.WZSGCF1-P1-C5-T1 0 2048 2048 FCS6 U78AA.001.WZSGCF1-P1-C1-C3-T1 1 64 64 2048 2047

A fabric of 1 indicates that the port is in use.

To execute a command:

$ lsdev-dev fcs6 name Status description fcs6 Available 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
