What is
Aquarium?

Copyright © SUSE 2021 4
Aquarium is....
• An Open Source Project (GPL3)
• Driven by the Storage team at SUSE
• A new approach on Ceph deployment and
management
• Opinionated version of a storage appliance
Aquarium isn't....
• A Ceph fork
• A SUSE product yet

Why are we doing
this?

— Ceph is incredibly flexible
— Can be too overwhelming for the average user
— We aim at reducing complexity
— Trading flexibility for intuitiveness
6

— Abstraction of complex concepts with simple terms
— Top-down approach to user requirements
— Deployment based on use cases
— Immediate feedback to the user on feasibility
7
We believe in

Architecture

— Python backend serving an Angular frontend over HTTP
— Started on system boot
— Not a container
– Because we need to run binaries that operate on the host
— Deploys, manages, and orchestrates Ceph containers on the
host

Quick Overview

Architecture
Overview
11

— Aquarium runs on every host
— Communication between nodes over web sockets
— Persistent state kept on etcd
— Each Aquarium node is mostly independent
– No leader, no followers
– Sync over etcd for statistics gathering
— Any node can serve the frontend to the user
12
Quick Overview

— openSUSE-based ram disk image per release
– From a USB stick, network, targeted cosmic rays
— Image contains the Aquarium binary
— Upgrading is as easy as changing the image and rebooting
13
Minimize Upgrade Path Pains

• Hostname
• Inventory (disks, nics, …)
• Utilization (disks, cpu, …)

• Initial cluster bootstrap
• Cluster extension
• Inventory
• Disks
• Nodes
• Utilization
• Capacity
• I/O rates
• Management
• NTP
• Gateway
deployment

• Services (file, obj, block)
• Allocated space vs
Capacity
• Constraint Solver

— Easy, guided install
– Working system from first node
— Abstract complex concepts
– No pools, no gateways, just services (File, Object, Block)
— Use-case driven service deployment
– Instead of fiddling with CRUSH maps, specify use-case
– for VMs might use all-flash
– File Backup might use Erasure Coding
— Immediate feedback to user on feasibility
– Depending on selected use-case
– And existing resources
18
But it's the Frontend that really shines...
