In this tutorial we going to setup and configure NexentaEdge iSCSI compatible service.

NexentaEdge Extended S3 API with High-Performance iSCSI provides unique benefits which can be useful for Machine Deep Learning, Big Data and IoT frameworks:

  • Access S3 objects as iSCSI LUNs
  • Mount S3 objects for fast File/POSIX access avoid unnecessary copy, fetch only needed datasets
  • Extended S3 feature set: Append, Range Writes, Object/Bucket snapshots, Key-Value Object access
  • Data Reduction with global inline de-duplication, compression and erasure encoding
  • Cost Reduction File/Block/DB access with S3 economics

Use cases details:

  • High-Performance iSCSI service with High-Availability built-in
  • Advanced Versioned S3 Object Append and RW "Object as File" access
  • S3 Object as a Key-Value database, including integrations w/ Caffe, TensorFlow, Spark, Kafka, etc
  • High-performance Versioned S3 Object Stream Session (RW), including FUSE library to mount an object
  • Management API for Snapshots and Clones, including Bucket instantaneous snapshots
  • Transparent iSCSI to/from S3 bucket access

OPTIONAL: Prior to installation please ensure that you have ACTIVATION_KEY token available. If not yet register DevOps account, obtain license key here: https://community.nexenta.com/s/devops-edition

Don’t stop now! The next scenario will only take about 10 minutes to complete.

Configuring NexentaEdge iSCSI Cluster

Step 1 of 4

Start NexentaEdge data node container

NexentaEdge is designed to be "shared-nothing" scale-out SDS solution where data storage containers spread out across physical server nodes connected via Ethernet network (we call it Replicast/UDP backend network). In this first step we will setup first host node as Edge data node with a location where to keep data blobs:

mkdir /var/tmp/data

In real deployments the above location ideally has to point to previously prepared mount point using ext4, xfs or zfs filesystems. More complex configuration allows usage of direct raw disk interface as well.

Now that we setup data blobs location, start nexenta/nedge daemon and Edge iSCSI compatible service

docker run --name iscsidata -v /etc/localtime:/etc/localtime:ro -v /var/tmp/data:/data -d nexenta/nedge start -j ccowserv -j iscsiserv

It will take few minutes for docker image to download. Please be patient..
