Inktank: CRUSH ALGORITHM

Ceph is in the Linux kernel and has been integrated with the leading open source cloud management platforms. Key to Ceph’s design is the autonomous, self-healing, and intelligent Object Storage Daemon (OSD). Storage clients and OSDs both use the Controlled, Replication, Under, Scalable, Hashing (CRUSH) algorithm to efficiently compute information about data containers on demand, instead of having to depend on a central lookup table.

CRUSH provides a better data management mechanism than older approaches and enables massive scale by cleanly distributing the work to all the clients and OSDs in the cluster. CRUSH uses intelligent data replication to ensure resiliency, which is better suited to hyper-scale storage. Let’s take a deeper look at how CRUSH works to enable modern cloud storage infrastructures.

Unlock Greater Value from DCIM with Asset Intelligence

"The data center is getting bigger and more complex and so too is the asset inventory. Every new asset has an impact on the day–to–day operations of the data center – from power consumption and problem resolution to capacity planning and change management. To achieve – and maintain – operational excellence, organizations don’t just need to know the location of their data center assets, they need to know if they are over-heating, under–performing or sitting idle."

Optimizing Capacity to Meet Business and IT Demands

Escalating competitive pressures, tight budgets and scarce capital resources are working in concert to intensify the importance of true alignment between IT and the organization it supports. But many of today’s enterprises are noticing a decided gap between what the business demands of IT and the realities of what IT can deliver.

Facebook Uses CA Technologies as the Foundation for its Broad DCIM Platform

Facebook is aiming to bring together data from IT, facilities and application development operations to facilitate workflow management and automation for greater operational efficiency of its datacenters. To that end, the company is developing an atypically extensive datacenter management software platform, which it has begun to deploy in some of its facilities. Facebook's datacenter infrastructure management (DCIM) system is 'hybrid' in that it includes both homegrown and commercial components.

Efficiency, Optimization and Predictive Reliability

IT organizations are increasingly being called upon to cost-effectively deliver reliable support for the entire catalog of business services, or risk outsourcing to a managed service provider. Previously, capacity planners and IT architects would use historical trends to predict capacity requirements and simply over-provision to account for any peaks caused by seasonality, error, or extraneous influences like mergers & acquisitions. Over-provisioning, combined with poor lifecycle management of new resources provisioned in the data center, has led to capacity utilization and inefficiency issues. While historical data is great for understanding past issues and current state of the environment, the performance of servers, hosts and clusters is not linear; at some level of saturation, the performance of that infrastructure will quickly start to degrade.

Get the Whole Picture: Why Most Organizations Miss User Response Monitoring and What to do About It

"End user response. To borrow a phrase, it’s where the rubber meets the road. You can be armed with vast amounts of performance metrics, but if you don’t know what users are actually experiencing, you don’t have the real performance picture. While this measure is critical, it is one many organizations fail to consistently capture. Why? This guide looks at the challenges of user response monitoring, and it shows how you can overcome these challenges and start to get a real handle on your infrastructure performance and how it impacts your users’ experience."

Softwaredefinierter Speicher: Weniger Speicherkosten, bessere Service-Levels

Einer aktuellen Umfrage der IDC zufolge erwägen rund 35 % der Unternehmen eine Investition in softwaredefinierte Speicherlösungen (SDS) im Jahr 2014. Dies stimmt mit den Ergebnissen von IDC-Gesprächen mit IT-Entscheidern überein, welche ihre Speicherarchitekturen der nächsten Generation entsprechend den steigenden Geschäftsanforderungen entwickeln und dabei die ITKosten reduzieren möchten.

SONDERDRUCK für Datacore Software

SANsymphony-V10 oder Virtual SAN – dieser Vergleich drängt sich auf, wenn die Speichervirtualisierung zum Einsatz kommen soll. Zudem spielt auch noch das Scale-out-Prinzip eine Rolle, wie es zum Beispiel von Nutanix favorisiert wird. Vor dem Hintergrund der Vorstellung und der Produktfreigabe von Version 10 von SANsymphony-V sowie der Freigabe von Virtual SAN soll eine vergleichende Darstellung die wesentlichen Unterschiede herausarbeiten.
