Navigating Product Name Changes for Marvell Ethernet Adapters at HPE

By Todd Owens, Technical Marketing Manager, Marvell

Hewlett Packard Enterprise (HPE) recently updated its product naming protocol for the Ethernet adapters in its HPE ProLiant and HPE Apollo servers. Its new approach is to include the ASIC model vendor’s name in the HPE adapter’s product name. This commonsense approach eliminates the need for model number decoder rings on the part of Channel Partners and the HPE Field team and provides everyone with more visibility and clarity. This change also aligns more with the approach HPE has been taking with their “Open” adapters on HPE ProLiant Gen10 Plus servers. All of this is good news for everyone in the server sales ecosystem, including the end user. The products’ core SKU numbers remain the same, too, which is also good.

For HPE Ethernet adapters for HPE ProLiant Gen10 Plus and HPE Apollo Gen10 Plus servers, the name changes were fairly basic. Under this new naming protocol, HPE moved the name of the adapter’s manufacturer to the front and added “for HPE” to the end. For example, what was previously named “HPE Ethernet 10/25Gb 2-port SFP28 QL41232HLCU Adapter” is now “Marvell QL41232HLCU Ethernet 10/25Gb 2-port SFP28 Adapter for HPE”. The model number, QL41232HLCU, did not change.

The table below shows the new naming for the HPE adapters using Marvell FastLinQ I/O technology and makes it very easy to match up ASIC technology, connection type and form factor across the different products.

Inevitably, there are a few challenges with the new approach, especially for the adapters used in Gen10 servers. The first is that the firmware in the adapters is not changing. So, when a customer boots up the server, the old model information, such as 524SFP+, will be displayed on the system management screens. The same applies to information passed from the adapter to other management software, such as HPE Network Orchestrator. However, in HPE’s configuration tools – One Config Advanced (OCA) – only the new names and model numbers appear, with no mention of the original numbers. This could create confusion when you’re configuring a system and it boots up, displaying a different model number than the one you are actually using.

Additionally, it is going to take some time for operating system vendors like VMware and Microsoft to update their hardware compatibility listings. Today, you can go to the VMware Compatibility Guide (VCG) and search on a 621SFP28 with no problem. But search on a QL41401 or QL41401-A2G, and you will come up empty. HPE is also working on updating its QuickSpec documents with the new naming, and that will take some time as well.

So, while the model number decoder rings are no longer required, you will need to have easy to access cross references to match the new name to the old model. To support you on this, we have updated all our key collateral for HPE-specific Marvell® FastLinQ® Ethernet adapters on the Marvell HPE Microsite. These documents were updated to include not only the new product names that HPE has implemented, but the original model number references as well.

Here are some links to the updated collateral:

Why Marvell FastLinQ for HPE? First, we are a strategic supplier to HPE for I/O technology. In fact, HPE Synergy I/O is based on Marvell FastLinQ technology. Value-add features like storage offload for iSCSI and FCoE and network partitioning are key to enabling HPE to deliver composable network connectivity on their flagship blade solutions.

In addition to storage offload, Marvell provides HPE with unique features such as Universal RDMA and SmartAN® technology. Universal RDMA provides the HPE customer with the ability to run either RoCE RDMA or iWARP RDMA protocols on a single adapter. So, as their needs for implementing RDMA protocols change, there is no need to change adapters. SmartAN technology automatically configures the adapter ports for the proper 10GbE or 25GbE bandwidth, and – based on the type of switch the adapter is connected to and the physical cabling connection – adjusts the forward error correction settings. FastLinQ adapters also support a variety of other offloads including SR-IOV, DPDK and tunneling. This minimizes the impact I/O traffic management has on the host CPU, freeing up CPU resources to do more important work.

Our team of I/O experts stands ready to help you differentiate your solutions based on industry leading I/O technology and features for HPE servers. If you need help selecting the right I/O technology for your HPE customer, contact our field sales and application engineering experts using the Contacts link on our Marvell HPE Microsite.

Top Eight Data Center Trends For Keeping up with High Data Bandwidth Demand

By Nick Ilyadis, VP of Portfolio Technology, Marvell

IoT devices, online video streaming, increased throughput for servers and storage solutions – all have contributed to the massive explosion of data circulating through data centers and the increasing need for greater bandwidth. IT teams have been chartered with finding the solutions to support higher bandwidth to attain faster data speeds, yet must do it in the most cost-efficient way – a formidable task indeed. Marvell recently shared with eWeek about what it sees as the top trends in data centers as they try to keep up with the unprecedented demand for higher and higher bandwidth. Below are the top eight data center trends Marvell has identified as IT teams develop the blueprint for achieving high bandwidth, cost-effective solutions to keep up with explosive data growth.

 

CloudComputing

 

1.) Higher Adoption of 25GbE

To support this increased need for high bandwidth, companies are evaluating whether to adopt 40GbE to the server as an upgrade from 10GbE. 25GbE provides more cost effective throughput than 40GbE since 40GbE requires more power and costlier cables. Therefore, 25GbE is becoming acknowledged as an optimal next-generation Ethernet speed for connecting servers as data centers seek to balance cost/performance tradeoffs.

2.) The Ability to Bundle and Unbundle Channels

Historically, data centers have upgraded to higher link speeds by aggregating multiple single-lane 10GbE network physical layers. Today, 100Gbps can be achieved by bundling four 25Gbps links together or alternatively, 100GbE can also be unbundled into four independent 25GbE channels. The ability to bundle and unbundle 100GbE gives IT teams wider flexibility in moving data across their network and in adapting to changing customer needs.

3.)  Big Data Analytics

Increased data means increased traffic. Real-time analytics allow organizations to monitor and make adjustments as needed to effectively allocate precious network bandwidth and resources. Leveraging analytics has become a key tool for data center operators to maximize their investment.

4.) Growing Demand for Higher-Density Switches

Advances in semiconductor processes to 28nm and 16nm have allowed network switches to become smaller and smaller. In the past, a 48-port switch required two chips with advanced port configurations. But today, the same result can be achieved on a single chip, which not only keeps costs down, but improves power efficiency.

5.) Power Efficiency Needed to Keep Costs Down

Energy costs are often among the highest costs incurred by data centers.  Ethernet solutions designed with greater power efficiency help data centers transition to the higher GbE rates needed to keep up with the higher bandwidth demands, while keeping energy costs in check.

6.) More Outsourcing of IT to the Cloud

IT organizations are not only adopting 25GbE to address increasing bandwidth demands, they are also turning to the cloud. By outsourcing IT to the cloud, organizations are able to secure more space on their network, while maintaining bandwidth speeds.

7.) Using NVM Express-based Storage to Maximize Performance

NVM Express® (NVMe™) is a scalable host controller interface designed to address the needs of enterprise, data center and client systems that utilize PCI-e based solid-state drives (SSDs.) By using the NVMe protocol, data centers can exploit the full performance of SSDs, creating new compute models that no longer have the limitations of legacy rotational media. SSD performance can be maximized, while server clusters can be enabled to pool storage and share data access throughout the network.

8.) Transition from Servers to Network Storage

With the growing amount of data transferred across networks, more data centers are deploying storage on networks vs. servers. Ethernet technologies are being leveraged to attach storage to the network instead of legacy storage interconnects as the data center transitions from a traditional server model to networked storage.

As shown above, IT teams are using a variety of technologies and methods to keep up with the explosive increase in data and higher needs for data center bandwidth. What methods are you employing to keep pace with the ever-increasing demands on the data center, and how do you try to keep energy usage and costs down?
