Making SATA Enterprise Ready - Technology Brief

A series of transformational IT industry trends are generating demand for low cost, high capacity hard disk drive (HDD) technologies. Serial ATA (SATA) has emerged as a potential disk drive alternative for those enterprises evaluating disk-based backup, grappling with new compliance requirements and considering tiered storage strategies.

FC technology use still leads despite Ethernet nipping at its heels

At least two technologies have tried to overtake Fibre Channel (FC) in the past decade: Ethernet and InfiniBand. Both have failed and FC use continues unabated. Why is that happening, and what's the future of FC?

Fibre Channel: The Proven and Reliable Workhorse for Enterprise Storage Networks

Mission-critical assets such as virtualized and database applications demand a proven enterprise storage protocol to meet their performance and reliability needs. Fibre Channel has long filled that need for most customers, and for good reason. Unlike competing protocols, Fibre Channel was specifically designed for storage networking, and engineered to deliver high levels of reliability and availability as well as consistent and predictable performance for enterprise applications. As a result, Fibre Channel has been the most widely used enterprise protocol for many years.

But with the widespread deployment of 10GbE technology, some customers have explored the use of other block protocols, such as iSCSI and Fibre Channel over Ethernet (FCoE), or file protocols such as NAS. Others have looked to Infiniband, which is now being touted as a storage networking solution. In marketing the strengths of these protocols, vendors often promote feeds and speeds, such as raw line rates, as a key advantage for storage networking. However, as we’ll see, there is much more to storage networking than raw speed.

It turns out that on an enterprise buyer’s scorecard, raw speed doesn’t even make the cut as an evaluation criteria. Instead, decision makers focus on factors such as a solution’s demonstrated reliability, latency, and track record in supporting Tier 1 applications. When it comes to these requirements, no other protocol can measure up to the inherent strengths of Fibre Channel in enterprise storage environments.

Despite its long, successful track record, Fibre Channel does not always get the attention and visibility that other protocols receive. While it may not be winning the media wars, Fibre Channel offers customers a clear and compelling value proposition as a storage networking solution. Looking ahead, Fibre Channel also presents an enticing technology roadmap, even as it continues to meet the storage needs of today’s most critical business applications.

In this paper, we’ll begin by looking at the key requirements customers should look for in a commercial storage protocol. We’ll then examine the technology capabilities and advantages of Fibre Channel relative to other protocols, and discuss how those translate to business benefits. Since not all vendor implementations are created equal, we’ll call out the solution set of one vendor – QLogic – as we discuss each of the requirements, highlighting it as an example of a Fibre Channel offering that goes well beyond the norm.

Hyperconverged storage challenges the SAN paradigm

HCI makes local storage cool again -- and it keeps pace with how VMs access and store data better than some traditional storage architectures.

Nutanix XCP For Demanding Enterprise Workloads: Making Infrastructure Invisible for Tier-1 Ent. Apps

Virtualization has matured and become widely adopted in the enterprise market. Approximately three in every five physical servers are deployed in a virtualized environment. After two waves of virtualization, it is safe to assume that a high percentage of business applications are running in virtualized environments. The applications last to deploy into the virtualized environment were considered the tier-1 apps. Examples of these include CRM and ERP environments running SAP NetWeaver, Oracle database and applications, and Microsoft SQL Server. In many 24X7 service industries, Microsoft Exchange and SharePoint are also considered tier-1 applications.

The initial approach to building virtualized environments that can handle these tier-1 applications was to build highly tuned infrastructure using best of breed three-tier architectures where compute, storage and networking were selected and customized for each type of workload. Newer shared storage systems have increasingly adopted virtualized all flash and hybrid architectures, which has allowed organizations to mix a few tier-1 workloads within the same traditional infrastructure and still meet stringent SLA requirements.

Enter now the new product category of enterprise-capable HyperConverged Infrastructure (HCI). With HCI, the traditional three-tier architecture has been collapsed into a single software-based system that is purpose-built for virtualization. In these solutions, the hypervisor, compute, storage, and advanced data services are integrated into an x86 industry-standard building block. These modern scale-out hyperconverged systems combine a flash-first software-defined storage architecture with VM-centric ease-of-use that far exceeds any three-tier approach on the market today. These attributes have made HCI very popular and one of the fastest growing product segments in the market today.

HCI products have been very popular with medium sized companies and specific workloads such as VDI or test and development. After a few years of hardening and maturity, are these products ready to tackle enterprise tier-1 applications?  In this paper we will take a closer look at Nutanix Xtreme Computing Platform (XCP) and explore how its capabilities stack up to tier-1 application workload requirements.

Nutanix was a pioneer in HCI and is widely considered the market and visionary leader of this rapidly growing segment. Nutanix has recently announced the next step - a vision of the product beyond HCI. With this concept they plan to make the entire virtualized infrastructure invisible to IT consumers. This will encompass all three of the popular hypervisors: VMware, Hyper-V and their own Acropolis Hypervisor. Nutanix has enabled app mobility between different hypervisors, a unique concept across the converged system and HCI alike. This Solution Profile will focus on the Nutanix XCP platform and key capabilities that make it suitable for teir-1 enterprise applications. With the most recent release, we have found compelling features appropriate for most tier-1 application workloads. Combined with the value proposition of web-scale modular architecture this provides an easy pathway to data-center transformation that businesses of all sizes should take advantage of.

End-to-End NVMe Storage: Is your enterprise ready?

In the past few years, flash technology has transformed the storage market forever. Today, flash-first arrays are the new normal. We believe the new NVMe-oF shared storage protocol combined with the advent of a broad range of NVMe-based devices including SCM will prove as disruptive to the external storage market over the next five years as NAND flash technology was in the recent past.

Read this Market Perspective to understand why now is the time to ask your storage vendors important questions about their array architectures, what questions to ask them, and how to interpret the answers. Arrays that efficiently read and write to SAS-based SSDs won’t see much gain from switching their backend to NVMe until the frontend also supports NVMe-oF. This report will explain why, when, and how this shift will take place.
