Hedvig: Install

Hardware

Minimum hardware for Each storage nodes :

General hardware recommendations Here are some general recommendations for your hardware, including nodes, servers, CPUs, memory, network, and disk drives. Number of nodes

• For a single cluster, have a minimum of three storage nodes.
• To scale performance and capacity, simply add nodes.
• It is best to add nodes in multiples of three, although they can be added in any quantity.

Type of servers

• The Hedvig standard is dual-socket x64 servers with onboard drives (SSDs and/or

HDDs).

• It is better to scale the cluster using a larger number of small capacity servers, as

opposed to using a smaller number of large capacity servers. Hedvig is optimized for scale-out. CPUs

• A multi-core Intel E5/E7 CPU, or equivalent, is best.
• In general, the latest CPU generations and models are best.

Memory

• The higher the memory capacity per node the better, because Hedvig utilizes memory

for internal processes and caching.

• The minimum memory configuration for each physical server for a Hedvig Cluster Node

(non-hyperconverged) is usually 48 GB. Typical deployments use servers with 128 to 256 GB. Network

• The Hedvig standard is a 10 GbE network, but 40 GbE is better.
• Gigabit is supported, but it is bandwidth limited.

Hedvig provide prebuild OVF templates / containers / ISO for deploy node and proxies node.

Prepare Storage node

• Install minimal Centos 6.7 on all storage nodes.
• All the drives should stay unformatted hedvig process take care of all formatting and setup.
• Set the root password to hedvig.

sudo su - passd

• Check all other nodes are accessible via SSH at port 22 .
• Add host names of all the other storage nodes , proxy and deploy node.
• Always enable jumbo frames, if available.

Download hedvig

Hedvig is available in number of formats ovf, iso ,containers.

The Hedvig software package can be downloaded from the Hedvig site, usually found here:

https://hedviginc.zendesk.com/hc/en-us

• Download /download/<release>/hedvig_extract.bin
• Download /download/<release>/rpm_extract.bin
• Download ftp://216.109.131.85/download/releases/images/ESX/cvm.ova
• Download ftp://216.109.131.85/download/releases/images/ESX/deploy.ova

Hedvig cvm and delpoy are available for kvm templates and ISO for bareborne servers.

Hedvig Storage Proxy

Minimum configuration for storage proxy is 4 cpus and 8GB ram. Higher clock speed cpu will be preferable.

• In hypervisor based setup ensure that we have 4 vcpus and 8GB of ram available.
• Install cvm.ova as appliance VM.
  • Inside VMWARE Vsphere client > file > Deploy OVF template
  • locate the cvm.ova template and follow the setup.

• After deploy start the VM and login via root and "hedvig" password.
• Setup appropriate fully qualified Host name.

• Update the /etc/hosts , so that all the hostnames(storage/proxy/deploy)are resolvable.
• Enable Jumbo frames.
• /usr/local/hedvig/scripts/menu_hedvig.sh

Hedvig Deployment server setup

• Import the deploy.ova into the ESXi or Vcenter. Please ensure you have atleast 1 vcpu and 4Gb for the deploy to work.
• Power up th VM and copy rpm_extract.bin and hedvig_extract.bin to /home/admin .(admin should be present in OVF)

scp rpm_extract.bin root@192.168.1.185:/home/admin scp hedvig_extract.bin root@192.168.1.185:/home/admin

• Change permissions.

chmod +x rpm_extract.bin chmod +x hedvig_extract.bin

• Execute as user admin.

sudo su admin sudo ./rpm_extract.bin sudo ./hedvig_extract.bin
