  • Softnas Deployment Guide for High- Performance SQL Storage
    SoftNAS Deployment Guide for High- Performance SQL Storage Introduction SoftNAS cloud NAS systems are based on an innovative, memory-centric storage architecture that delivers unparalleled NAS performance, efficiency, and value. They incorporate a hybrid disk storage technology that tailors the usage of data disks, log solid- state cache drives (SSDs), and read cache SSDs to the data share's specific needs. Additional features include variable storage record size, data compression, and multiple connectivity options. As a Cloud NAS solution, SoftNAS cloud NAS systems provide an excellent base for Microsoft Windows Server deployments by providing iSCSI or Fibre Channel block storage for Microsoft SQL Server, and network file system (NFS) or server message block (SMB) file storage for Microsoft Windows client access. This document covers the best practices to follow when deploying Microsoft SQL Server on a SoftNAS cloud NAS system. The intended audience is storage administrators and Microsoft SQL Server database administrators. Maintaining High Availability As with any business-critical application, high availability is a crucial design criterion to be considered when deploying a Microsoft SQL Server installation. Microsoft SQL Server 2016 can be installed on local and/or shared file systems, and SoftNAS cloud NAS systems can satisfy both of these options. Local file systems (from the Microsoft Windows Server perspective) are hosted as block volumes—iSCSI and/or Fibre-Channel-connected LUNs and file systems as SMB and/or NFS volumes. High availability starts with the network connectivity supporting the storage and server interconnectivity. Any design for the storage infrastructure should avoid single points of failure. Because many white papers and publications cover storage-area networking and network-attached storage resilience, those topics are not covered in detail in this paper.

  • File Systems
    File Systems Profs. Bracy and Van Renesse based on slides by Prof. Sirer Storing Information • Applications could store information in the process address space • Why is this a bad idea? – Size is limited to size of virtual address space – The data is lost when the application terminates • Even when computer doesn’t crash! – Multiple process might want to access the same data File Systems • 3 criteria for long-term information storage: 1. Able to store very large amount of information 2. Information must survive the processes using it 3. Provide concurrent access to multiple processes • Solution: – Store information on disks in units called files – Files are persistent, only owner can delete it – Files are managed by the OS File Systems: How the OS manages files! File Naming • Motivation: Files abstract information stored on disk – You do not need to remember block, sector, … – We have human readable names • How does it work? – Process creates a file, and gives it a name • Other processes can access the file by that name – Naming conventions are OS dependent • Usually names as long as 255 characters is allowed • Windows names not case sensitive, UNIX family is File Extensions • Name divided into 2 parts: Name+Extension • On UNIX, extensions are not enforced by OS – Some applications might insist upon them • Think: .c, .h, .o, .s, etc. for C compiler • Windows attaches meaning to extensions – Tries to associate applications to file extensions File Access • Sequential access – read all bytes/records from the beginning – particularly convenient for magnetic tape • Random access – bytes/records read in any order – essential for database systems File Attributes • File-specific info maintained by the OS – File size, modification date, creation time, etc.

  • Backupassist and Windows Server 2012
    BackupAssist and Windows Server 2012 BackupAssist v7.1 and later, in a Windows Server 2012 environment. BackupAssist 7.1 & Windows Server 2012 Windows Server 2012 introduces new technologies and features that can affect how BackupAssist operates. This resource explains how some of the key changes impact BackupAssist and what you need to know when performing backups and restores in a Windows 2012 environment. Resilient Files System (ReFS) ReFS is a new file system that introduces reliability and compatibility features to Windows Server. BackupAssist supports ReFS formatted drives as a backup source and destination for all backup types. BackupAssist can also restore from ReFS formatted drives. Considerations: File Protection backups cannot use single-instance store when the backup is saved on a ReFS formatted destination. This means all of the data will be backed up each time the backup job runs. System Protection cannot incrementally back up data from a ReFS formatted drive (source). This means a full backup of all selections will take place each time the backup job runs. De-duplication De-duplication for Windows Server 2012 is a technology that efficiently stores and transfers data using less space. All BackupAssist backups can operate in a de-duplicated environment. Considerations: BackupAssist will backup files from a de-duplicated volume in the non-optimized mode. Therefore, the backup will not retain the de-duplicated format. Server Message Block Server Message Block (SMB) is a network protocol for sharing resources. SMB 3.0 includes changes such as improved performance and VSS support. BackupAssist supports SMB 3.0 as both a backup source and destination.

Invented by IBM in 1983, SMB has become Microsoft’s core protocol for shared services like files, printers etc. Initially SMB was running on top of non routable NetBIOS/NetBEUI API and was designed to work in small to medium size workgroups. 1996 Microsoft renamed SMB to Common Internet File System (CIFS) and added more features like larger file sizes, Windows RPC, the NT domain service and many more. Samba is the open source SMB/CIFS implementation for Unix and Linux systems 2 © Leutert NetServices 2013 www.wireshark.ch Server Message Block (SMB) Protokoll SMB over TCP/UDP/IP SMB over NetBIOS over UDP/TCP SMB / NetBIOS was made routable by running Application over TCP/IP (NBT) using encapsulation over 137/138 139 TCP/UDP-Ports 137–139 ..

    White paper Cisco public Implementing SMB File Services on Cisco HyperFlex Using Microsoft Windows Server Virtual Machine November 2020 © 2020 Cisco and/or its affiliates. All rights reserved. Page 1 of 17 Contents Executive summary 3 Introduction to Cisco HyperFlex systems 4 Implementing SMB file services on Cisco HyperFlex using Microsoft Windows Server Virtual Machine (VM) 6 Engineering validation 12 Conclusion 17 © 2020 Cisco and/or its affiliates. All rights reserved. Page 2 of 17 Executive summary This paper describes the best practices to deploy Microsoft Windows Server – Server Message Block (SMB) file services on Cisco HyperFlex™. SMB file-sharing solutions can be architected in several ways; this paper addresses a single Virtual Machine (VM) configuration with a high-availability option. The Cisco HyperFlex is a purpose-built Hyperconverged Infrastructure (HCI) for private and hybrid cloud data centers. When deploying hyperconverged solutions, there are no prerequisite operations such as Logical Unit Number (LUN) provisioning, Host Bus Adapter (HBA) compatibility checks, or Fibre Channel (FC) LUN zoning operations. Cisco HyperFlex delivers extreme performance, VM density, and a wide variety of powerful data management features for an enterprise-scale private cloud environment. Microsoft Windows Server SMB file services on Cisco HyperFlex provide enterprise-grade storage for user home directories and profiles. The solution described in this paper has been tested by Cisco in our lab only for the purpose of assisting with best practices when used with Cisco HyperFlex. The licensing and support of the SMB file services using Microsoft Windows Server software is handled directly by Microsoft. Audience The intended audience for this document includes, but is not limited to, sales engineers, field consultants, providers of professional services, IT managers, partner engineers, and customers deploying SMB file services on Cisco HyperFlex.
