This document provides a baseline design standard for tier 2 NetApp storage. It specifies that NetApp filers provide file sharing using CIFS and NFS, with snapshots taken twice daily and backups to tape storage six nights a week. The filers use clustering for fault tolerance and data is replicated between data centers using Snapmirror. The baseline configuration includes dual heads, redundant power supplies, and management with Data Fabric Manager.

Tier 2 net app baseline design standard revised nov 2011
- 1. Unit/Project Name: Enterprise Technology Document Name: Tier 2 NetApp Baseline Design Standard Date: August 13th 2009 Tier 2 NetApp Baseline Design Standard Directly Impacted Teams: X86 Servers Unix Servers Data Storage Data Networking Voice Services Monitoring Data Center Other____________ Scope: Enterprise Wide Alaska California Oregon Washington/Montana Other____________ Baseline Design Standard Summary The NetApp Filers provide tier 2 storage and are used primarily for file sharing. They utilize Active Directory for controlling access to the file shares. Each volume on the Filers corresponds to a share. Twice daily a NetApp snapshot is made of the volumes, and these snapshots are kept for 30 days. These snapshots are available for end user restore via the “Previous Versions” method available in the rightclick menu on Windows clients. The Filers are also backed up to TSM six nights a week and these backups are kept for 90 days. Selective restore of files in the 30-90 day timeframe is available and requires an administrator to initiate the restore. Snapmirror is used to replicate filers between data centers. Replication can be used in lieu of TSM backups. In Alaska, we do have some Fibre Channel LUNS allocated on WAFL. The NetApp Snapdrive utility is the multipathing driver. (This use is not currently in favor, and presenting additional storage in this fashion in the future is not anticipated.) The Base configuration: The filers are accessed by customers using the CIFS and NFS protocols. (AK, TBC,RDC, and CA use is 95%+ CIFS.) Filers have two heads and are clustered for fault tolerance. Filers have redundant power supplies. Filers are managed with Data Fabric Manager ( OnCommand Core Package).
- 2. Deduplication is used to save space on volumes. Considerations: The filers currently use TSM to coordinate the backups, store and retrieve the TOC (table of contents), and as an interface for selective restore of files. The filers use SAN attached tape drives in the same tape pools as TSM. Volumes that do not need snapshots typically do not have them configured. This saves space on the Filer. Use Cases Case Tier 2 Storage Tier 3 Storage NAS CIFS NFS FTP server Fibre Channel and Snapdrive Multistore Usage Not recommended for FC connectivity Used for archive storage and disaster recovery Best File sharing platform for Windows because of the snapshotting/replication and other integrated tools make them easy to upgrade expand/grow reduce/shrink shift data around easily Used as an Oracle platform that does not require High IO’s , gives you replication functionality and sharpshooting natively. Used on UNIX platforms to give CIFS (windows) access to UNIX files. Used on VMWare for its back end shared storage Excellent for this because of reduced space required because of De-duplication technology 50-70% Space Reduction without impact to performance. Integrated dedupe and replication for DR. FTP functionality. Allows LUNS to be allocated on the filers and offered over the SAN to hosts. The multipath driver is not as desirable as on other storage platforms. This tends to limit Fibre Channel use. Allows Windows fileservers contents to be more easily moved onto filers. (No need to consolidate shares and folders to just the one filer.) Page 2 of 6
