Flash is really fast, and performance-hungry applications must be able to access it wherever it is located. Luckily, NVMe can take advantage of flash throughout a computer system.
However, accessing flash over a network can introduce problems which designers must solve. Accesses can take much longer than local flash, latency can rise significantly, networking issues can raise their ugly heads, and performance can vary greatly depending on network load and competition for resources.
Ways to solve such problems include sequence-level error recovery, prioritization for virtualized environments, and improved forward error correction. And – surprise! – all these are already part of the Fibre Channel standard or the emerging FC-NVMe transport protocol.
The growth and centralization of mission critical datacenter SAN environments has exposed the fact that many small yet seemingly insignificant problems have the potential of becoming large scale and impactful events, unless properly contained or controlled. Root cause analysis requirements now encompass all layers of the fabric architecture, and new storage protocols that usurp the traditional network stack (i.e. FCoE, iWARP, NVMe over Fabrics, etc.) for purposes of expedited data delivery place additional analytical demands on the datacenter manager. To be sure, all tools have limitations in their effectiveness and areas of coverage, so a well-constructed “collage” of best practices and effective and efficient analysis tools must be developed. To that end, recognizing and reducing the effect of those limitations is essential.
This webcast introduces Protocol Analysis tools and how they may be incorporated into the “best practices” application of SAN problem solving. We will review:
- The protocol of the Phy
- Use of “in-line” capture tools
- Benefits of purposeful error injection for developing and supporting today’s high-speed Fibre Channel storage fabrics
Learn how you can save your SAN (and your sanity!)
Interoperability is a primary basis for the predictable behavior of a Fibre Channel (FC) SAN. FC interoperability implies standards conformance by definition. Interoperability also implies exchanges between a range of products, or similar products from one or more different suppliers, or even between past and future revisions of the same products. Interoperability may be developed as a special measure between two products, while excluding the rest, and still be standards conformant. When a supplier is forced to adapt its system to a system that is not based on standards, it is not interoperability but rather, only compatibility.
Every FC hardware and software supplier publishes an interoperability matrix and per product conformance based on having validated conformance, compatibility, and interoperability. There are many dimensions to interoperability, from the physical layer, optics, and cables; to port type and protocol; to server, storage, and switch fabric operating systems versions; standards and feature implementation compatibility; and to use case topologies based on the connectivity protocol (F-port, N-Port, NP-port, E-port, TE-port, D-port).
In this session we will delve into the many dimensions of FC interoperability, discussing:
• Standards and conformance
• Validation of conformance and interoperability
• FC-NVMe conformance and interoperability
• Interoperability matrices
• Multi-generational interoperability
• Use case examples of interoperability
It’s 2018, and Fibre Channel continues to remain the dominant SAN fabric protocol in today’s data centers. Fibre Channel is deployed in 90 percent of the Fortune 1000 data centers in the world and 80 – 90 percent of all All-Flash storage arrays are connected to servers via Fibre Channel. The fact that Fibre Channel was built from the ground up, and with an intense focus on enterprise storage array connectivity, gives the technology a unique edge over other networking technologies in terms of rock-solid reliability, unmatched performance and massive scalability…
The heart and soul of any technology, and the industry association that stewards the technology, is its technology roadmap. Just like the term suggests, a roadmap shows not just the history of a technology, but also is a guide to where it is going and when it is going to get there…
When companies invest in a technology, they want to know that they will get a return on their investment for years to come. Fibre Channel has had a very accurate roadmap for over a decade and this document shows the past, present and future of the Fibre Channel physical layer. Fibre Channel has been progressing since 1996 by doubling the data rate every few years and this roadmap shows that the progression will continue far into the future. Fibre Channel continues to outpace other physical layer technologies like Ethernet and will continue to surpass them in speed…
The availability of the NVMe standard has radically changed the landscape for solid-state storage, driving commoditization of the media along with aggressive competition for density and performance. This media revolution is causing a secondary pair of disruptions in the storage array space. The first disruption is the move toward NVMe-based SSDs (rather than SAS- or SATA-based SSDs) as the media of choice on the All-Flash array back end. The second disruption is a move toward NVMe over Fabrics, and particularly NVMe over Fibre Channel, as the emerging high-performance protocol for accessing enterprise storage…
The IT world is moving toward Hybrid Cloud Infrastructure. Customers in large numbers are choosing applications that need to be deployed on premise but need some interactions and/or compute/data mobility with the cloud. Most tech savvy IT managers are aware of pros and cons of on-prem versus the cloud. Tier 0 and tier 1 applications with sensitivity to application up-time, failover disaster recovery, storage replication requirements continue to be deployed on premise in order to reduce business risk. Cost of downtime for most businesses continues to be very high. The cloud has certainly…
Since its introduction in 1994, Fibre Channel has become well recognized as the leading technology choice for storage attachment – it delivers superior scale, reliability, dependability and manageability. That much is pretty obvious. What’s not so obvious is that in the late 1990s, when Fibre Channel was evolving, the S/390 mainframe architects realized that this technology would provide an excellent “next” underlying transport for mainframe I/O, replacing the technology being used at that time known as ESCON…
The choice between using Fibre Channel (FC) or other protocols is dictated by several factors, one of them being whether a dedicated SAN is required and/or desirable. Ethernet SANs are implemented in the context of a converged network or at the minimum sharing of switch ports for multiple use cases. Although, we see a rampant use of dedicated iSCSI fabrics also. FC networks are always utilized as dedicated SANs. For some use cases a dedicated SAN is not an option. In others, the mission critical nature of the application alone justifies a dedicated SAN…
