Our community is talking about the new Dell Technologies. Join the discussion in the Dell EMC Community Network:
To quote the great American author Mark Twain, “The report of my death has been grossly exaggerated”, and this very much applies to Java.
Java is very much alive and kicking, as is the management interface to the PS Series array. However, it is the end of the line for the Netscape Plugin Application Programing Interface (NPAPI), which has enabled many web browser plug-ins and extensions, including Java. So from Java’s perspective, the end of NPAPI is only a minor setback, one that is best summarized by the words of another great writer (and actor) John Cleese: "It's just a flesh wound!"
NPAPI was first released in 1995 with Netscape Navigator 2.0, and was supported by every major browser released since then. This allowed plug-ins and extensions to be developed for web browsers, enabling a host of rich content to be accessed through a simple desktop browser. That was until 2014, when major web browsers announced that the end was nigh. This was mainly due to the API’s age, security issues and the strong adoption of plug-in free browser technologies such as HTML5. The end of NPAPI brings to an end the once-popular Java web browser plug-in used by many interfaces, including the one provided with PS Series storage.
So what does this mean for managing your Dell PS Series array? This is not the end of the line for Java. It is just the end of the ability to launch Java applications from within a web browser. You can still manage your PS array using the same user interface as you always have. You just can’t launch it from a web browser:
However, after some minimal ground work, you’ll be back in business — browser-free and using Java:
And that’s it!*
That is not your only option. For those who are also SC Series storage customers, earlier this year we released Dell Storage Manager (DSM) 2016 R1, the successor to the SC Series Enterprise Manager. While DSM is part of the SC Series ecosystem, it has been extended to manage Dell PS Series arrays running firmware 7.0 and above. You can take this a step further if you have both PS and SC arrays in your environment, and replicate in either direction between PS and SC storage. For more information, see this two-part video series on day-to-day management of PS Series with DSM, as well as this solutions guide and video series on replicating between PS and SC Series arrays.
For those who wear the dual hats of vSphere and storage administrator, the Dell Virtual Storage Manager enables full management of PS Series storage from within the vSphere Web Client. This includes everything from provisioning VMFS, NFS (FS76xx required) or a VVol datastore, to protecting virtual machines with application-consistent, array-based snapshots and configuring block-based replication for disaster recovery of your virtual environment. You won’t ever have to leave the comfort of the vSphere Web Client.
Finally, there is the ever-present CLI, which can be taken a step further using scripts. Windows PowerShell, along with the Host Scripting Tools, which support both Windows and Linux with Perl and Python. These scripting tools enable not only day-to-day management, but also extend PS Series capabilities into areas not currently covered by Dell Host Integration Tools for Microsoft, VMware and Linux.
When the last of the browsers disables NPAPI, it won’t be missed. It has already been replaced and no one will shed a tear. But it will be remembered for the important part it played in the history of the internet and the richness it brought to our simple web browsers for over 20 years.
*The fine print: Depending upon your OS, browser and Java versions and security settings, there may be additional steps. This KB article covers some additional combinations. But the essence is the same — get the Java applet and run it directly in Java.
Earlier this year, Dell announced its collaboration with Microsoft on Software for Open Networking in the Cloud (SONiC). SONiC is a collection of open source software networking packages/modules that can be installed on Linux on a network hardware switch which makes it a complete, functional router. Dell’s collaboration with Microsoft is intended to encourage the open source community to innovate, collaborate, adopt and contribute.
Today, Dell strengthens this collaboration by announcing significant contributions to the key building blocks of the SONiC architecture. We are also announcing that Dell has open sourced all of its software components in OS 10 Open Edition under the SONiC project in OCP. These enhancements are intended to elevate the platform, reinforce the synergy between the SONiC contributors, and provide maximum value to the development community.
Dell offers a new object model schema to SONiC along with PAS (Platform Abstraction Services) and NAS (Network Adaptation Services). Platform Adaptation Services interacts with the hardware components of the switch such as power modules, fan trays and LEDs. Network Adaptation Services provides APIs to program the NPU/ASIC that support SAI standard ASIC SDK. These contributions can be found here. The following wiki provides further information on this submission.

Dell’s OS10 Open edition has been extensively tested to ensure integrity. This open edition acts as a building block of the commercial version of Dell’s Networking System (OS10 Enterprise Edition). For more information about OS10 Open Edition and access to architecture documentation, installation instructions please visit – OS10 Open Edition Documentation
SONiC currently offers two ASIC switch control software components namely, Switch State Services and Network Adaptation Services.
The NAS (ASIC switch control software) version comes with a full feature set including
The roadmap includes completion of integration of SONiC with OS10 Open Edition by the end of 2016. Dell welcomes the community to follow the integration effort closely in the existing SONiC forums. For more information about SONiC, and access to community resources please visit https://azure.github.io/SONiC/.
Figure 2: Target SONiC High Level Architecture
SONiC allows end users to rapidly prototype control plane applications and design purpose-built data centers, thus optimizing overall network design. Today’s SONiC feature set is focused on the datacenter. The move to open networking allows end users to focus on developing applications and opens the door to groundbreaking innovations.
We welcome the participation of the open source community and we look forward to seeing SONiC being adopted to accelerate growth in the networking Industry. Together we can build network switch software and provide an open platform for applications to grow through the adoption of a disaggregated network stack.

The ever increasing demand for high-quality communication and exponential growth in smart phone subscribers has put a tremendous pressure on Telecom service providers (TSPs) to continuously upgrade backend infrastructure. TSPs are also in heated battle with over-the-top (OTT) service providers, like Google and Microsoft, to provide the unified communications (UC) services to the same consumer. Complicating matters further, TSPs must also contend with roaming service options and the reallocation of existing 3G voice spectrum to more efficient HSPA or LTE.
To meet this challenge of rapid growth in demand, traditional telco solutions are expensive and not easy to scale to growing demand. As a result TSPs are now beginning to utilize Network function virtualization (NFV) based virtual IP Multimedia Subsystems (vIMS). These vIMS reduce deployment and operating expenses while improving functionality and flexibility compared to traditional IMS solutions.
Dell, Intel, Red Hat and Metaswitch have partnered to develop a best of the breed vIMS solution. The solution is built on Dell PowerEdge servers, storage and switches. Red Hat software provides a secure and very scalable platform to deliver public or private Infrastructure-as-a-Service (IaaS) solutions. Metaswitch provides vSBC technology to support voice/video calls as well as the analytics for real time statistical reporting.
To learn more about this solution, please see the vIMS solution brief from Dell and its partners. To schedule a demo of this turnkey setup, please reach out to NFV solutions team at Dell at firstname.lastname@example.org. Last but not least, more information on Dell NFV solutions can be found at www.Dell.com/NFV

Earlier this summer, Dell released Storage Center OS (SCOS) 7.0 and Dell Storage Manager (DSM) 2016 R1, which included major features such as VMware Virtual Volumes, improved data reduction, PS Series bidirectional replication to SC Series (cross-platform replication) and volume Quality of Service (QoS). David Glynn wrote about those features in his blog post, which describes DSM as a single interface to manage the Dell Storage platforms including PS Series, SC Series and FluidFS.
Now, with the release of SCOS 7.1 and DSM 2016 R2, we built upon those features and added enhancements to zero downtime, connectivity, disk support, and visibility into the age of disks.
New with SCOS 7.1 and DSM 2016 R2 is Federation Live Migrate. This feature takes advantage of the array statistics and intelligence of SCOS to provide the best placement of volumes in an environment with multiple SC Series systems. When a volume is live migrated to another SC Series system, the volume advisor can help the user to pick the most appropriate SC Series system for placement. The volume is then migrated without disruption to applications or I/O, improving the efficiencies of day-to-day management while at the same time optimizing the usage of the SC Series arrays. David Glynn demonstrates this in the SC Series Live Migrate best practices document.
To follow the zero-downtime theme, our Dell Storage engineers enhanced Live Volume with the nifty Automatic Failover feature to include not only VMware vSphere (since SCOS 6.7) but also Microsoft Hyper-V. Designed with continuous operations in mind, Live Volume with Automatic-Failover (LV-AFO) does not have a downtime penalty during planned or unplanned outages. To get your hands on this feature, you will need at least two SC Series arrays along with SCOS 7.1 and DSM 2016 R2. Marty Glaser provides all the details in a very thorough video and solutions guide.
In addition, be sure to read about the improvements made with VMware support for Site Recovery Manager (SRM) in the best practices document and video by Jason Boche. Jason and Mike Matthews also give specifics for Microsoft SQL Server disaster recovery with VMware SRM in this white paper. Jason has been very busy this summer and will quench your thirst for VMware Virtual Volumes (VVols) best practices in this paper.
Our engineers have worked hard to improve connectivity options by providing the Dell Storage SC4020 with 12 Gb SAS front-end ports. Why is that important? SAS front-end connectivity allows you to redundantly, directly connect up to four servers each with two SAS ports, without the need for a single SAN switch. Marty Glaser shows you the way with Hyper-V as an example in this solutions guide, and Chuck Armstrong describes how to configure SC4020 SAS with VMware in this solutions guide. Speaking of connectivity, front-end throughput capability improves with the support of 32 Gb FC front-end ports for the Dell Storage SC9000 (of course, only the HBAs and switches listed in the Dell Storage Compatibility Matrix should be used). I should also mention that the limits have doubled for the SC9000 snapshots and replications, along with the ability to ingest up to a petabyte (PB) of data for deduplication.
For some time, disks have been formatted with the relatively small sector size of 512 bytes. The trend of larger disk capacities has increased the complexity of the I/O operations dramatically. This is best put into words using a quote from Richie Lary, which describes flying a "747 1/100 of an inch off the ground at 2,500,000 miles per [hour], with the pilot able to read the spots on a set of dominos" (assuming a disk scaled to the size of a 747). With SCOS 7.1 and 4K native disk support, I/O can be better aligned for large disks, with improved I/O efficiency and enhanced media error correction, all while increasing format efficiencies.
Data integrity has been a focus for some time for Dell Storage engineers, and features like disk scrubbing and background checking are core components of the SCOS base. Now with SCOS 7.1, the ANSI Technical Committee for SCSI Storage Interfaces Protection Information (PI) standard is supported on 4K-sector HDDs and self-encrypting drive (SED) SSDs. This support improves the data integrity verification across those 12 Gb SAS back-end data paths to the disks.
Have you ever wondered how long your disks have been powered on? As you know, the longer a disk ages, the probability of disk failure increases. Conveniently, the standard for disk manufactures is to track the power-on hours. Our Dell Storage engineers have exposed those statistics to DSM, as well as to Dell SupportAssist1. Of course, this is presented in a friendly fashion in DSM by indicating the number of years, months, days or hours each drive has been powered on. Since Dell currently warranties most disks to five years, this feature will provide insight into when disks are near their warranty life span.
That’s all for now. Have a great day!
1SupportAssist is the Dell centralized support collection and management system. Storage information is “phoned home” based on a user-defined schedule.
