13 IBM Storwize V7000 Unified Integrates Storage Administration Integrates file and block applications in a single storage system Adds supports for file access protocols - NFS, CIFS, FTP, HTTPS, SCP Supports file replication and snapshots for business continuity 13 13

14 The V7kU File Modules Additional hardware and software on top of the V7k File Modules (FMs) provide file services CIFS, FTP, HTTP(S), NFS, and SCP Software stack originates from the Scale Out NAS (SONAS) product Large system made of many racks of nodes and storage Highly scalable clustered solution Roots in the Scale Out File Services (SoFS) project 14 14

15 A Glance at SONAS to Better Understand the V7kU The SONAS system is comprised of 3 types of nodes or roles Node Management Node Storage Node The interface node provides the connections to the customer s IP network for file serving capabilities (CIFS, NFS, HTTPS, FTP). The management node provides the user interface for configuring, administering and monitoring the SONAS system. The storage node provides the connection to the backend storage SONAS R1.3 combines the management and interface roles into 1 node pair, yet allows for many more interface nodes Highly scalable The V7kU shrinks the SONAS system further by combining all 3 roles into a single node pair 2 File Modules 15 15

16 V7kU Connections 10 GbE NAS IO Customer s Switch GbE GPFS Sync Direct Cable Connections GbE Management Customer s switch 8Gb Fibre Channel Direct Attach (No Switch) SAS 4 lanes at 6 Gbps per strand (24 Gbps), 2 strands per SAS Chain (48 Gbps), 2 SAS chains (96 Gbps), Totaling 600 MBps full duplex 16 16

17 Requirements for customer infrastructure Authentication server (choose one) Windows Active Directory (with optional SFU or NIS) LDAP (Lightweight Directory Access Protocol) Samba PDC (optional with NIS) Load Balancing/Name Resolution DNS round-robin, each incoming request allocated to next available IP adress on a file module Time server for synchronization NTP service required to synchronize file modules with authentication services Network Connectivity Ports: 4 x 1 GbE for File Modules, min. 2 x 1 GbE for V x IP adresses for File Modules and V7000 control canisters Management: 1 x IP adress for Unified cluster and min. 1x IP adress for V7000 cluster Optional 10GbE for file service (3x) or iscsi attachment V7000 (2x) Min 1x public IP adress per interface for file services (recommended: 2x) Optional: Backup server: choice of NDMP or TSM TSM HSM 17 Antivirus scan engine

18 V7kU Environment Customer Provided Services Authentication Server Domain Name Server Network Time Server (Optional) Remote V7kU File Modules V7kU Software delivered as a single IBM program product All needed V7kU software components are packaged, integrated, tested, & pre-installed at the factory on V7kU hardware Network Shared Disk Via Fibre Channel * * TSM/HSM or NDMP over Ethernet only 18 18

19 V7kU Installation V7k USB key process has been extended to cover entire V7kU Process flow: On Windows workstation enter IP addresses for V7000 and File Modules Plug USB key into V7k Wait for blinking light to stop Remove USB key Then plug USB key into one of File Modules Wait for blue blinking lights to go off Remove USB key Return USB key to Windows workstation to confirm results USB key configures network addressing between V7k & V7kU Allows them to refer to and address each other USB key also carries credential (ssh key) from V7k to File Module Enables secure communications between the two Utilizes the NasUser role 19 19

20 File System Volume Management Commands provided to configure volumes for file system use mkdisk, mkfs (for GPFS) These commands will perform multiple steps automatically Configure volume on V7k (mkvdisk) Create NSD in GPFS Add NSD to GPFS file system File system volumes are marked with the file system to which they belong Known to V7k layer and reported in Volumes panels of the GUI Volumes that are in a file system have a restricted command set According to those functions that are supported and work as needed No FlashCopy, Metro Mirror or Global Mirror Cannot be thin provisioned Cannot use volume mirroring No migration between storage pools or to image mode Cannot be resized 20 20

21 Management Integration V7kU presents a single management interface to cover all aspects of the system Graphical User (GUI) hosted on File Module provides access to all features Command Line (CLI) hosted on File Module forwards requests to File or Block layers as needed 21 21

22 Management Access All management access is via the V7kU V7k commands generated in V7kU then forwarded to the V7k V7K GUI elements integrated into V7kU GUI 22 22

24 IBM Active Cloud engine for V7kU

25 IBM Active Cloud Engine for Storwize V7000 Unified Policy-based File Administration Optimize performance by placing files onto the most appropriate storage pool Lower storage costs over time by moving inactive files to archive disk or tape, and deleting unwanted, expired files Improve administrator productivity by automating file management Improve data protection with policy-based file backup Files Storage Pools Migrate inactive data to tape, tape lib, or de-duplication device via TSM Server 25

26 IBM General Parallel File System IBM General Parallel File System (GPFS) Clustered file system across multiple hardware nodes Basis of the SONAS technology which the V7kU leverages In continuous development since 1995 Developed for High Performance Computing (HPC) Has run on 3900 nodes with 4 PBs of storage GPFS provides Concurrent high-speed file access to applications executing on multiple nodes of clusters Single flat file system V7kU in the simplest sense is a two node SONAS cluster with a V7k providing disks 26 26

27 Network Shared Disks GPFS file systems span across multiple physical disks These disks are called Network Shared Disks (NSDs) Storage pools are logical collections of disks Each storage pool contains disks with similar performance characteristics V7kU has a V7k providing disks Both V7k internal and virtualized external storage The NSDs that are visible to GPFS are V7k Vdisks Usually made up of multiple disks 27 27

28 Fastest disk pool in the file system is Pool 1. In a file system with tiered pools, this is SAS pool. Pool 2 is a customer named user pool If HSM is used, Pool 3 is the external pool, which is managed by the external TSM Server 28 SAS NSD SAS NSD TSM Server FILE SYSTEM NL SAS NSD NL SAS NSD NL SAS NSD POOL1 SAS NSD SAS NSD POOL2 POOL3 NL SAS NSD NL SAS NSD NL SAS NSD EXTERNAL POOL Physical or Virtual Tape Storage V7kU Storage Pools Perform complex operations such as moving, mirroring, or deleting files; providing storage virtualization and a single management context. Partition file system storage for considerations such as: Improved price-performance by matching the cost of storage to the value of the data Improved performance by: Reducing the contention for premium storage Reducing the impact of slower devices Allowing you to retrieve archived data when needed Improved reliability by providing for: Replication based on need Better failure containment Creation of new storage pools as needed Two types of storage pools: Internal Storage Pools Max of 8 per file system 1 required as the system storage pool 7 for user pools External Storage Pools Intended for use as near-line storage 28
