Consolidate OS in corporate datacenter with E4C (WP)

In this White Paper, we demonstrated the benefits of a consolidation of virtual machines with identical Operating Systems over the same physical hosts. The benefits are both financial and technological. The financial benefits consist of a lower license spending for Operating Systems, and increased control over spending. The main technological benefit is an increased memory sharing among Virtual Machines, which is useful to increase the VM density per physical host.

Saving energy in datacenters with Eco4Cloud and Cisco UCS

This white paper frames the workload consolidation topic and provides an overview of state-of-the-art approaches, including Eco4Cloud. Moreover, the document clarifies how Eco4Cloud can be profitably integrated with Cisco Unified Computing System (UCS). Indeed, the abstraction of resources offered by Cisco UCS is the perfect starting point for the workload consolidation provided by Eco4Cloud: UCS creates a homogeneous environment tailored to applications migration and dynamic server hibernation and resume.

ROI modeling in a standard Eco4Cloud deployment

Eco4Cloud uses a three-step methodology for conducting ROI analysis:

  1. Gather quantitative benefit information. In this study, the benefits amount to energy savings in a data center, while costs amount to the E4C license purchase and renewal.
  2. Create a complete investment (three-year total cost analysis) profile based on costs and benefits.
  3. Calculate the ROI and payback period. E4C conducts a depreciated cash flow analysis of the investments over a three-year period.

The final results on a mid-range data center are 111% ROI, with 7 months of payback period.

Managed Service Provider

A large Managed Service Provider has selected Eco4Cloud’s technology to deliver significant cost savings in their highly virtualized and multi­tenanted cloud environment. Eco4Cloud actively manages the number of powered­on cores in the server estate resulting in significant reductions in electricity costs (30%) due to reduced server power draw and reduced cooling demands. In addition they have been able to deliver Server Thin Provisioning, provisioning only the number of physical servers that their customers use, rather than the number that they request. This feature is common in storage environments but is unique to Eco4Cloud in the virtualization world.
The sum total of benefits include: reduced data center space, reduced numbers of physical servers, reduced power and cooling demands all of which lead to better ROI/profitability and a more competitive offer to clients.

Large Enterprise

A large enterprise firm has selected Eco4Cloud to manage their test and development environments. Eco4Cloud have been able to manage a constantly changing workload where different environments are in use at different times, without over provisioning the physical server estate or consuming unnecessarily large quantities of electricity for servers that are doing no practical work. All of this is done seamlessly and automatically with no administrator intervention.
Eco4Cloud’s Smart Ballooning memory technology enables memory to be actively managed and put where it is needed as workload moves depending on test patterns and schedules. Eco4Cloud also manages the active cores that the whole workload needs to deliver service, ensuring that sufficient cores are always available but never more than are needed consuming cash and other resources.
Benefits include: optimization of RAM and CapEx deferral/reduction for the purchase of additional capacity, OpEx reduction due to energy savings >30%, increased health posture of the virtualization infrastructure as crucial parameters such as CPU Ready-Time and Memory Ballooning have dramatically improved.

Outsourcing

An outsourcing firm has selected Eco4Cloud to provide assistance in migrating workload from Windows 2003 to Windows 2014. Whilst the underlying server estate was largely suitable for the upgrade there was insufficient headroom to manage the swing of services from one operating system to the other. Eco4Cloud shrunk the existing estate to make that headroom and provide free physical servers to support the migration.
Benefits include: business agility due to reduction of migration period, CapEx savings as no additional hardware was required to support the migrations operations, higher computing density at final steady­state.

Scientific Overview

The Eco4Cloud project originates from years of research activities of a group of four researchers of the ICAR-CNR Institute of the National Research Council of Italy. The four researchers – Agostino Forestiero, Raffaele Giordanelli, Carlo Mastroianni, and Giuseppe Papuzzo – are among the co-founders of the company, later recognized as a spin-off from the CNR and the University of Calabria. The core product, the software for the dynamic consolidation of workloads in data centers, founds on an innovative decentralized/probabilistic algorithm based on the swarm intelligence paradigm and on bio-inspired techniques. The expertise and skills of the CNR research group allowed the very complex consolidation problem (known to be NP-hard, i.e. exponential, when tackled in a classical centralized/deterministic fashion) to be solved efficiently even in large data centers.

These issues are covered in the following scientific overview.
