5 Introducing SOFS

6 The Problem While SANs offer lots of functionality They are EXPENSIVE A problem for: The SME that would like a small cluster The massive data centre that needs lots of storage Inflexible Client scalability limited by fabric switches Hardware defined storage 6

7 The Solution Scalable & continuously available SMB 3.0 storage * Otherwise known as The File Server for Application Data cluster role Otherwise known as The Scale-Out File Server 7

8 What SOFS Offers Ability to use cheap storage: Storage Spaces The SAN(s) you already own Simplify LUN configurations Use the skills you already know File shares Clustering Windows networking Present storage as SMB 3.0 shares to Hyper-V hosts Use those shares for clustered and non-clustered hosts Live migration options that SAN can t offer Zero downtime cluster migrations 8

9 Failover Clustering

10 Cluster Storage - WS2012 & Later Option PCI RAID SAS SAN iscsi SAN Fibre Channel SAN FCoE SAN Storage Spaces!!! SMB 3.0 Shared Folders Support For Clusters? Yes Yes Yes Yes Yes Yes Yes

11 Cluster Shared Volumes (CSVs) Microsoft s cluster file system Volumes are active on all nodes in the cluster Changes in WS2012: New Redirected I/O-free synchronised single-vss snapshot backup CSV Cache: Use up to 20% of cluster nodes RAM as a read cache Changes in WS2012 R2: CSV Cache: Use up to 80% of cluster nodes RAM as a read cache See Scale-Out File Server

12 Scale-Out File Server

13 Scale-Out File Server (SOFS) Software-defined storage Place 2-8 cluster nodes in front of cluster supported storage SAS/iSCSI/FC/FCoE SANs, PCI RAID, JBOD + clustered Storage Spaces Create Cluster Shared Volumes (CSVs) on storage Active/active cluster file system Create File Server for Application Data role on cluster (the SOFS) Active/active Create file shares on SOFS, stored on CSVs Permission to servers (Hyper-V) and administrators Store data (virtual machines on file shares)

14 Features of WS2012 SOFS Scalable & Continuously Available Storage That s 2 drinks in the Windows Server drinking game! Scalable Add more nodes, storage, or networking Active/Active disks CSV Active/Active shares SOFS ( File Server for Application Data ) role Continuously available (all automatic) SMB Client redirection and SMB Multichannel It s just Windows Server administration!

19 Changes to WS2012 R2 SOFS CSV ownership is (re-)balanced automatically SMB clients continue to connect to any node But redirected to owner of the CSV that share is placed on Much better performance when combined with CSV ownership balancing Dedicated SMB Server instance for Redirected IO Caused by metadata operations and storage path fault tolerance Can do bare-metal SOFS deployment from SCVMM 2012 R2
