Chapter 1Introduction

Topics:

• Product Overview

Product Overview

HybriStor™ provides a deduplicating interface for either locally-attached storage or Swift object storage.The front end of the HybriStor™ server consists of either Network File System (NFS) or CommonInternet File System (CIFS) shares.

A future version of HybriStor™ will support clustered operations, thereby, allowing several HybriStor™servers to operate together to allow increased performance, large capacities, and fault tolerance.

Architecture

The HybriStor™ product is offered as both a virtual appliance to be deployed in a virtual environmentand also as a DVD/ISO to be installed in an existing environment consisting of either physical hardware,virtual machines, or a combination of both.

This document addresses the installation of HybriStor™ when deployed in either environment.

Object Storage and Local Storage for Data Storage

Neverfail® HybriStor™ can be used with an object storage backend for data or with local, file systemstorage for data. When used with local storage, that local storage can use either software RAID,hardware RAID, or other protection. It is not recommended to use no redundancy at all for a productionenvironment.

In addition to the storage for data, HybriStor™ also requires processing storage and index storage.

Note: The processing storage is always local and must be SSD for performance purposes.

Object Storage

Currently, HybriStor™ supports the use of the Swift object storage system for data storage.

Note: Other object storage systems are being tested for possible inclusion as supported systems.

Local Storage Using Software RAID

The data storage is local on the HybriStor™ server.The operating system provides redundancy thoughthe use of software RAID. When software RAID is used for the data storage, software RAID is alsoused for the processing and index, and is suggested for the operating system.

Local Storage Using Hardware RAID

The data storage is local on the HybriStor™ server. Data redundancy is offered below the operatingsystem level, allowing the operating system to see single volumes. When Hardware RAID is used forthe data storage, hardware RAID is also used for the processing and index, and is suggested for theoperating system.

4Neverfail

Note: This option is also appropriate when no redundancy is desired (for example, demo, test, ortraining).

c) When the Deploy OVF Template dialog is displayed, follow the on-screen instructions andbrowse to the .ova file you previously downloaded and click Next.

d) Review the details of the OVA, and click Next.e) Review the End User License Agreement, click Accept, and then click Next.f) Assign a Name for the virtual machine, select a Folder for the virtual machine, and click Next.g) Select a storage resource for the virtual machine and click Next.h) Leave the default Thick Provision Lazy Zeroed for disk provisioning, select a storage capacity

of at least 80 GB of free capacity, and then click Next.

Note: For performance reasons, it is recommended that you use Thick Provision Lazy Zeroedfor disk provisioning.

i) Setup networking as appropriate and click Next.j) Review your configuration and click Finish to complete importing the virtual machine.

2. Configuring the appliance with VMWare vSphere Web Client.

Adding New Disks

a) Right-click on the virtual machine that you just deployed/imported and select Edit Settings.b) In the New device field located at the bottom of the Edit Settings dialog, select New Hard Disk

and click Add.c) Adjust the size of the hard disk you just added to at least 50 GB for Processing Disk.d) Double-click on New Hard disk, select Store with the virtual machine, and click Browse in the

Location field to select the disk that you have pre-configured with SSD.e) If your license includes InstaCache™, repeat steps b, c and d to add a new 400 GB hard disk

for InstaCache™.f) Repeat steps b, c and d to add a new hard disk with at least 300 GB in size for Index Disk.g) Repeat steps b, c and d to add a new hard disk with 1-10 TB in size for Data Disk.

Network Configuration

The HybriStor™ appliance, by default, comes configured with one network adapter (VMXNET 3)using DHCP on the VM Network. If your environment supports VMXNET 3 and DHCP, skip thissection and go to step 3.

a) Right-click the appliance and select Edit Settings.

Neverfail6

Installation Guide

b) In the Network adapter 1 field, click on VM Network and select an appropriate network for yourenvironment.

c) Double-click on Network adapter 1 and ensure Connect at Power On is selected in the Statusfield.

d) Click OK to save the settings.

3. Powering on the VM

a) Right-click the HybriStor™ appliance and select Power On. Navigate to the Summary page ofyour HybriStor™ appliance in VMware vSphere Web Client to launch the console.

b) The default user is root and the password is Changeme123$.You are required to change thepassword as soon as you login.

4. Changing Network Adapter Settings

Note: Skip this step and go to step 5 if your network adapter type is VMXNET 3 and you can useDHCP.

For VMXNET 3 Network Adapter

If your network adapter type is not VMXNET 3, go to the next section to configure non-VMXNET3 network adapter.

If your network adapter type is VMXNET 3 and you want to use static IP instead of the defaultDHCP for the VM, you can edit the following network configuration file with the added/modifiedcontents bolded in the example below.

Network configuration file: /etc/sysconfig/network-scripts/ifcfg-ens160

Example:

Save the file and execute the following command to restart the network service and make thechanges effective: systemctl restart network.service

For non-VMXNET 3 network adapter

Skip this step if your network adapter type is VMXNET 3. If your network adapter type is not VMXNET3, follow the steps below.

a) Execute the ifconfig command to identify network adapter name.

Example:ens33 is the network adapter name in this example.

b) Make a copy of the original network file by executing the following command.cp /etc/sysconfig/network-scripts/ifcfg-ens160 /root/

c) Rename the original network file name to match the real adapter name by executing the followingcommand. In our example, the file ifcfg-ens160 should be renamed to ifcfg-ens33.mv /etc/sysconfig/network-scripts/ifcfg-ens160/etc/sysconfig/network-scripts/ifcfg-ens33

d) Edit the new network file (which is ifcfg-ens33 in our example) by executing the followingcommand:vi /etc/sysconfig/network-scripts/ifcfg-ens33

e) If the environment supports DHCP, edit the bolded options and save the file after editing.

Note: The Host Bus Adapter (HBA) requirements above have been carefully selected and tested tosupport TRIM on SSDs. The use of RAID adapters is not recommended due to the lack of supportfor passing through TRIM commands to SSDs even when configured in "Just a bunch of disks" (orJBOD) mode.

In this configuration, deduplicated data is stored in a local Swift object storage cluster. In a productionenvironment, it is recommended that Swift cluster nodes use 10GbE network adaptors. The clustershould contain a minimum of five storage nodes managing at least 100 nearline SAS or SATA7200-RPM hard drives. Account and container storage is required to be on SSD drives due to the highIOPS incurred.

BInstallation Tips and Best Practices

Installation on a Physical Server

Method 1: Installing from a DVD

Burn a CD/DVD from an ISO file.

1. Place the DVD in the server DVD tray.2. Activate the boot menu and boot from the DVD.3. Follow this installation guide to finish installing the product.

Method 2: Install from Remote Access Console (Dell iDRAC, HP iLO, IBM IMM, etc)

Please refer to your server document on how to mount and boot from an ISO image via a VirtualCD/DVD. Follow this installation guide to finish installing the product.

Method 3: Install from USB Flash Drive

1. Create a bootable USB Flash drive from the ISO image.

a. Plug the USB flash drive into the server. Perform a quick format.

Caution: This will erase all your data on the USB drive.

Make sure the file system is FAT32 and the Volume label is HYBRISTOR.

44Neverfail

b. Download ISO2USB for CentOS/RedHat from this URL:http://iso2usb.sourceforge.net/
