EMC ECS is a stateful, containerized, object storage system for cloud storage protocols. ECS is compatible with AWS S3 and OpenStack Swift. On file-enabled buckets, ECS can provide NFS exports for file-level access to objects.

ECS can be set up on one or more hosts or virtual machines in a single-site or a multi-site geo replicated configuration. We want the wider community to use ECS and provide feedback. Usage of this software is under the End User License Agreement at the bottom of this README.

ECS Community Edition is a free, reduced footprint, version of Dell EMC’s ECS software. Of course, this means there are some limitations to the use of the software, so the question arises; how is the Community Edition of ECS different from the production version?

As noted with the included license, ECS Community cannot be used in production environments and is intended to be used for trial and proof of concept purposes only. This software is still owned and protected by Dell EMC.

It it important to note that ECS-Community Edition is not the same as ECS software and as such lacks some features that are integral to the actual ECS software.

• ECS Community Edition does NOT support encryption
• ECS Community Edition does NOT include ECS’ system management, or “fabric”, layer

Because of these differences, ECS Community Edition is absolutely not qualified for testing failure scenarios. Failure scenarios can only be adequately mimicked on the full version of ECS Software.

If you have the following:

1. A CentOS Minimal install of the latest CentOS release with:
   1. 16GB RAM
   2. 16GB block device for system
   3. 104GB block device for ECS
2. Internet access
3. No proxies, local mirrors, or special Docker registries

Then you should be able to get up and going with a Single-Node All-in-One install using these commands on your VM:

# git clone https://github.com/EMCECS/ECS-CommunityEdition
# cd ECS-CommunityEdition
# cp docs/design/reference.deploy.yml deploy.yml
# echo "Edit this deploy.yml to match your VM's environment"
# vi deploy.yml
# ./bootstrap.sh -y -g -c deploy.yml

And then after the node reboots (you did use a clean minimal install from ISO or netinstall right?):

# step1
# step2

And if all went well, you now have a working stand-alone ECS, mostly configured, and ready for use.

Note: A minimum configuration is only suitable for short-term sandbox testing
Hardware or virtual machine with:

• 4 CPU Cores
• 16GB RAM
• 16GB root block storage
• 104GB additional block storage
• CentOS Minimal installation of the latest CentOS release

Note: A recommended configuration is more suitable for longer-term functional testing
Hardware or virtual machine with:

• 8 CPU Cores
• 64GB RAM
• 16GB root block storage
• 1TB additional block storage
• CentOS Minimal installation of the latest CentOS release

Deploy a stand-alone instance of ECS to a single hardware or virtual machine.

Deploy a multi-node ECS instance to two or more hardware or virtual machines. Three nodes are required to enable erasure-coding replication.

Please be aware that install node bootstrapping requires Internet access to the hardware or virtual machine that will become the install node, but once this step is complete, the machine can be removed from the Internet and migrated into the Island environment.

In situations where Internet access is completely disallowed, or for the sake of convenience, an OVA of a prefabricated, bootstrapped, install node is provided. Please download the OVA from one of the links below.

The OVA is shipped as a bootstrapped install node. It must be cloned multiple times to create as many Data Store Nodes as desired.

• All nodes MUST be clones of the OVA.
• All nodes MUST have their virtual hardware configurations updated to match the node type requirements.

• The default password for the admin accounts is ChangeMe. The default password for root is unknowable.
• For security reasons, it is strongly advised to change the password for admin immediately after installation.

• The OVA is configured to acquire network settings via DHCP. Static configurations must be manually configured with sudo nmtui

Please see the release page for OVA download links.
Please validate the package integrity against the provided sha512 hash mentioned for a release, before commencing deployment.

Using an install node for isolated environments, deploy a stand-alone instance of ECS to a single hardware or virtual machine.

Using an install node for isolated environments, deploy a multi-node ECS instance to two or more hardware or virtual machines. Three nodes are required to enable erasure-coding replication.

This is the repository for the projects of Performance Evaluation and Application course held at Polimi.

Performance Evaluation is the quantitative and qualitative study of systems, to evaluate, measure, predict and ensure target behaviors and performances. The main topics of the course are:

• Introduction to performance indices and measures
• Workload and Service characterization
• Analytical models
• Simulation and resource contention

The coverage of this topics was done through the development of 20 assignment and a final project to put in practice all the knowledge acquired.

🛠️ All the projects were developed in MatLab and Java Modeling Tool (JMT).

In the relative folder all the 20 assignments are present. For each assignment a Matlab\JMT application is present with the source code and the relative pdf file with the task specification. Sometimes a dataset is provided.

The final project is a analysis of a embedded system development cycle, where the company need to know best number of projects N that they should work on at the same time, to produce the best tradeoff between throughput and project completion time mixing all the knowledge acquired during the course.

The project is divided using both Matlab and JMT. In the relative folder is present:

• The specification of the project (pdf)
• 2 matlab project used for data analysis
• JMT project used for the simulation of the system (jmt)
• The final report of the project (pdf)
• A folder with the dataset used for the project

✔️ Final Evaluation: 30 cum laude/30
