Converged Data Management Unwrapped – Software Converged

As a technologist, I find a certain amount of joy comes from learning about what’s new in the market. This could be as simple as a new code or hardware release for a solution that has been around for a while, driving me to absorb the new features. Or, on the other end of the spectrum, it could be an entirely new way of thinking about how to tackle a challenge within the data center by learning from startups who are looking to shake things up with an interesting idea. A common pain point is figuring out exactly what it is that the young company does, as often the technical bits get blended in with a bunch of marketing jargon and buzzwords (see my buzzword bingo parody video) that dilute the transfer of information. In this series, I’m going to get a little nerdy about a relatively new term that is hitting the market, Converged Data Management, and dive into the five important properties that build into this solution. The goal is to provide a clear view into each feature with real meat on the bone, along with why and how the solution is important in today’s modern data center,…

Managing and Monitoring SLA Domains at Global Scale

In my previous post, I went into the complexities that funnel into building Service Level Agreements (SLAs) that exist between consumers and providers of an IT service. This friction can be greatly assuaged by decoupling the agreed upon policy’s intent from the actual execution of backup jobs. It allows administrators to abstract away much of the low-end fuss required to build and maintain data protection, instead focusing on adding value at a more strategic level across the organization. Let’s now move the story forward to discuss how consumers can easily determine if their SLAs are being honored. At a high level, SLA Domains are constructed using Recovery Point Objective (RPO) and retention values. The RPO is essentially asking how much data loss the consumer is willing to tolerate, while the retention input determines where the provider will store data (on-premises or elsewhere). To understand SLA compliance, it’s important to look at the entire set of backup jobs to ensure all facets of the RPO are being met for an application. This goes beyond looking at the number of total backups held by the system, as an RPO is often expressed as a quantity of hourly, daily, weekly, monthly, and yearly…

Decoupling Policy from Execution with SLA Domains

Successful enterprise architects are able to pull functional design elements from key stakeholders to abstract requirements, constraints, and risks. Much of this work involves translating business needs into technology decisions and then deciding upon the right vendor solutions to provide for the design. In this blog post series, I’m going to focus on addressing Service Level Agreements (SLAs) to ensure that the business is equipped with the runway it needs to tackle operational challenges and protect applications. Many organizations that I’ve consulted with were forced to take a good, hard look at their SLAs (or lack thereof) in order to craft a strategic plan for the future. At the heart of any quality SLA is fairness. Both parties – the consumer and the provider of a service – must agree on a mutually beneficial statement for long term success. The end goal is to abstract the minutiae of a technical design away from the consumer. Such as this WordPress platform: I really don’t concern myself with the back end infrastructure, I just want to consume the service and know that it’s being protected. An SLA is a method for me to define guard rails around data loss and availability while…
