The chapter includes the following topics: Overview of MPFS over FC and iscsi EMC VNX MPFS architectures How VNX MPFS works Introducing EMC VNX MPFS over FC and iscsi 17 Introducing EMC VNX MPFS over FC and iscsi Overview of MPFS over FC and iscsi EMC VNX TM series Multi-Path File System (MPFS) over Fibre Channel (FC) lets Linux, Windows, UNIX, AIX, or Solaris servers access shared data concurrently over FC connections, whereas VNX MPFS over Internet small computer system interface (iscsi) lets servers access shared data concurrently over an iscsi connection. MPFS uses common Internet Protocol local area network (IP LAN) topology to transport data and metadata to and from the servers. Without the MPFS file system, servers can access shared data by using standard network file system (NFS) or Common Internet File System (CIFS) protocols; The MPFS file system accelerates data access by providing separate transports for file data (file content) and metadata (control data). For an FC-enabled server, data is transferred directly between the Windows server and storage over an FC storage area network (SAN). For an iscsi-enabled server, data is transferred over the IP LAN between the Windows server and storage for a VNX or VNX VG2/VG8 configuration. Metadata passes through the VNX for file (and the IP network), which includes the network-attached storage (NAS) portion of the configuration. 18 EMC VNX Series MPFS over FC and iscsi v6.0 Windows Clients Product Guide Introducing EMC VNX MPFS over FC and iscsi EMC VNX MPFS architectures Three basic VNX MPFS architectures are available: VNX MPFS over FC VNX MPFS over iscsi VNX MPFS over iscsi/fc The FC architecture consists of the following configurations: EMC VNX5300, 5500, 5700, or 7500 with FC VNX VG2/VG8 with FC The iscsi architecture consists of the following configurations: VNX5300, 5500, 5700, or 7500 with iscsi VNX VG2/VG8 with iscsi The iscsi/fc architecture consists of the following configurations: VNX with iscsi/fc VNX VG2/VG8 with iscsi/fc VNX MPFS over Fibre Channel The VNX MPFS over FC architecture consists of the following: VNX with MPFS A NAS device configured with a VNX and MPFS software VNX for block or Symmetrix Windows servers with MPFS software connected to a VNX through the IP LAN, VNX for block, or Symmetrix by using FC architecture Figure 1 on page 20 shows the VNX over FC configuration where the Windows servers are connected to a VNX Series (VNX for file and VNX for block in a single cabinet) by using an IP switch and one or more FC or FC over Ethernet (FCoE) switches. In a smaller configuration of one or two servers, the servers are connected directly to the VNX Series without the use of FC or FCoE switches.

Instead, the MPFS file system interoperates and uses the standard NFS and CIFS protocols to enforce access permissions. The MPFS file system uses a protocol called File Mapping Protocol (FMP) to exchange metadata between the Windows server and the VNX for file. All requests unrelated to file I/O pass directly to the NFS/CIFS layer. The MPFS layer intercepts only the open, close, read, and write system calls. When a Windows server intercepts a file-read call, it sends a request to the VNX for file asking for the file's location. The VNX for file responds with a list of file extents, which the Windows server then uses to read the file data directly from the disk. When a Windows server intercepts a file-write call, it asks the VNX for file to allocate blocks on disk for the file. The VNX for file allocates the space in contiguous extents and sends the extent list to the Windows server. The Windows server then writes data directly to disk, informing the VNX for file when finished, so that the VNX for file can permit other Windows servers to access the file. The remaining chapters describe how to install, manage, and tune Windows servers. Using VNX Multi-Path File System technical module, available on EMC Online Support at provides information on the MPFS commands. 24 EMC VNX Series MPFS over FC and iscsi v6.0 Windows Clients Product Guide Invisible Body Tag 2 EMC VNX MPFS Environment Configuration This chapter presents a high-level overview of configuring and installing the EMC VNX MPFS.
