For Trade – My 2017 iMac (Loaded) for your LG UltraFine 5k x 2 or 4k x 3 displays (or one or two plus cash).

Hello all,

Recently upgraded my on the move 2013 13″ Retina MacBook Pro to a 2017 15″ Retina MacBook Pro (2.9GHZ i7, 16GB Ram, 512GB storage, Radeon Pro 560) and the iMac didn’t get that much use before and now it pretty much has no use as with the screen being larger than my previous I’m quite happy with it being my main machine.

I the iMac specs are as follows:

  • 27″ 5K display
  • 4.2 up to 4.5GHZ i7
  • 8GB Ram (ordered the base amount as was going to upgrade myself saving £££ from apple to never got around to it)
  • 512GB Flash Storage
  • Radeon Pro 580 with 8GB VRAM
  • Magic Mouse 2 and Apple keyboard
  • Have the original Apple Box etc and the computer is in perfect working order (photos to follow).
  • It was bought on the 10/08/17 so just out of warranty but is in perfect working order.

Im ideally looking to trade for two LG UltraFine 5k displays or three 4k displays. If you have less then the monitor plus cash my way. Not looking to trade for anything else.

Explore the Cubic congestion control provider for Windows

Administrators may not be familiar with the Cubic congestion control provider, but Microsoft’s move to make this the default setting in the Windows networking stack means IT will need to learn how it works and how to manage it.

When Microsoft released Windows Server version 1709 in its Semi-Annual Channel, the company introduced a number of features, such as support for data deduplication in the Resilient File System and support for virtual network encryption.

Microsoft also made the Cubic algorithm the default congestion control provider for that version of Windows Server. The most recent preview builds of Windows 10 and Windows Server 2019 (Long-Term Servicing Channel) also enable Cubic by default.

Microsoft added Cubic to Windows Server 2016, as well, but it calls this implementation an experimental feature. Due to this disclaimer, administrators should learn how to manage Cubic if unexpected behavior occurs.

Why Cubic matters in today’s data centers

Congestion control mechanisms improve performance by monitoring packet loss and latency and making adjustments accordingly. TCP/IP limits the size of the congestion window and then gradually increases the window size over time. This process stops when the maximum receive window size is reached or packet loss occurs. However, this method hasn’t aged well with the advent of high-bandwidth networks.

For the last several years, Windows has used Compound TCP as its standard congestion control provider. Compound TCP increases the size of the receive window and the volume of data sent.

Cubic, which has been the default congestion provider for Linux since 2006, is a protocol that improves traffic flow by keeping track of congestion events and dynamically adjusting the congestion window.

A Microsoft blog on the networking features in Windows Server 2019 said Cubic performs better over a high-speed, long-distance network because it accelerates to optimal speed more quickly than Compound TCP.

Enable and disable Cubic with netsh commands

Microsoft added Cubic to later builds of Windows Server 2016. You can use the following PowerShell command to see if Cubic is in your build:

Get-NetTCPSetting| Select-Object SettingName, CcongestionProvider

Technically, Cubic is a TCP/IP add-on. Because PowerShell does not support Cubic yet, admins must enable it in Windows Server 2016 from the command line with the netsh command from an elevated command prompt.

Netsh uses the concepts of contexts and subcontexts to configure many aspects of Windows Server’s networking stack. A context is similar to a mode. For example, the netsh firewall command places netsh in a firewall context, which means that the utility will accept firewall-related commands.

Microsoft added Cubic-related functionality into the netsh interface context. The interface context — abbreviated as INT in some Microsoft documentation — provides commands to manage the TCP/IP protocol.

Prior to Windows Server 2012, admins could make global changes to the TCP/IP stack by referencing the desired setting directly. For example, if an administrator wanted to use the Compound TCP congestion control provider — which was the congestion control provider since Windows Vista and Windows Server 2008 — they could use the following command:

netsh int tcp set global congestionprovider=ctcp

Newer versions of Windows Server use netsh and the interface context, but Microsoft made some syntax changes in Windows Server 2012 that carried over to Windows Server 2016. Rather than setting values directly, Windows Server 2012 and Windows Server 2016 use supplemental templates.

In this example, we enable Cubic in Windows Server 2016:

netsh int tcp set supplemental template=internet congestionprovider=cubic

This command launches netsh, switches to the interface context, loads the Internet CongestionProvider template and sets the congestion control provider to Cubic. Similarly, we can switch from the Cubic provider to the default Compound congestion provider with the following command:

netsh int tcp set supplemental template=internet congestionprovider=compound

AT&T revives Office@Hand UCaaS deal with RingCentral

In an unexpected move, AT&T will continue supporting and reselling RingCentral’s unified-communications-as-a-service platform as part of a new partnership targeting the large-enterprise market. 

AT&T had informed customers in January 2018 that, within a year, it would no longer support RingCentral’s Office@Hand, a cloud-based calling and messaging platform the carrier had been selling to small and midsize businesses.

But, this week, the two companies struck a new deal: AT&T will now start selling the UCaaS product to large enterprises, as well as SMBs. Scott Velting, an associate vice president with AT&T, attributed the about-face to “rapidly changing market dynamics and technological advances.”

RingCentral previously purchased AT&T’s customer licenses for Office@Hand in an agreement worth up to $26 million. The startup cautioned investors that revenue could be “significantly and adversely affected” if too many of those customers declined to transition from AT&T to RingCentral.

While some of those customers have already migrated, the businesses that have not yet switched will be able to remain on the Office@Hand platform through AT&T, RingCentral said.

Leading up to the earlier decision to end the partnership, Office@Hand sales had stagnated, with an “immaterial” number of new subscriptions sold in all of 2017, according to RingCentral. Sales through the AT&T channel accounted for 11% of RingCentral’s revenue that year — down from 14% in 2016. 

With the new deal announced this week, the technology behind Office@Hand is the same, but RingCentral appears to have developed a more robust strategy for working with service-provider partners like AT&T, said Jeremy Duke, founder and chief analyst at Synergy Research Group, based in Reno, Nevada.

RingCentral is “currently growing at more than the average growth rate for the UCaaS market, and they want to continue that growth,” Duke said. “And they see the AT&T relationship as very important to continue building that momentum.”

RingCentral has more than doubled its revenue over the past three years, from $220 million in 2014 to $501 million last year, according to federal regulatory filings.

“I think this move helps RingCentral in its efforts to move upmarket. We continue to see RingCentral posting strong growth numbers; this expanded partnership should only help,” said Irwin Lazar, analyst at Nemertes Research, based in Mokena, Ill.

AT&T partners with several other UCaaS vendors, including Cisco and BroadSoft, which was recently acquired by Cisco. It also has its own cloud communications platform, AT&T Collaborate.

Vendors target large enterprises with UCaaS

While SMBs drove most of the initial growth of the UCaaS market, more and more enterprises are also now buying cloud calling plans.

UCaaS sales in the enterprise market are growing at twice the rate of sales in the SMB market, according to data released last month by Synergy. There are now nearly 8 million UCaaS seats worldwide, a twofold increase since late 2015, the firm said.

As of the second quarter of 2018, RingCentral remains the leader, with an 18% market share, trailed by Mitel at 16%, 8×8 at 13%, Cisco at 7%, and Vonage at 7%, according to Synergy. Mitel recently acquired UCaaS vendor ShoreTel.

Still, UCaaS platforms account for less than 10% of the total PBX market, according to Synergy.

“Our data shows that larger enterprises are still laggards when it comes to adopting UCaaS, but interest continues to grow,” Lazar said.

Windows troubleshooting tools to improve VM performance

Whether virtualized workloads stay on premises or move to the cloud, support for those VMs remains in the data center with the administrator.

When virtualized workloads don’t perform as expected, admins need to roll up their sleeves and break out the Windows troubleshooting tools. Windows has always had some level of built-in diagnostic ability, but it only goes so deep.

Admins need to stay on top of ways to analyze ailing VMs, but they also need to find ways to trim deployments to control resource use and costs for cloud workloads.

VM Fleet adds stress to your storage

VM Fleet tests the performance of your storage infrastructure by simulating virtual workloads. VM Fleet uses PowerShell to create a collection of VMs and run a stress test against the allocated storage.

This process verifies that your storage meets expectations before deploying VMs to production. VM Fleet doesn’t help troubleshoot issues, but it helps confirm the existing performance specifications before you ramp up your infrastructure. After the VMs are in place, you can use VM Fleet to perform controlled tests of storage auto-tiering and other technologies designed to adjust workloads during increased storage I/O.

VM Fleet tests the performance of your storage infrastructure by simulating virtual workloads.

Sysinternals utilities offer deeper insights

Two Windows troubleshooting tools from the Microsoft Sysinternals collection, Process Explorer and Process Monitor, should be staples for any Windows admin.

Process Explorer gives you in-depth detail, including the dynamic link library and memory mapped files loaded by a process. Process Explorer also lets you dig in deep to uncover issues rather than throwing more resources at an application and, thus, masking the underlying problem.

Process Explorer
Process Explorer lets administrators do a technical deep dive into Windows processes that the Task Manager can’t provide.

Process Monitor captures real-time data of process activity, and Registry and file system changes on Windows systems. It also provides detailed information on the process trees.

Administrators can use Process Monitor’s search and filtering functions to help administrator focus on particular events that occur over a longer period of time.

VMMap and RAMMap detail the memory landscape

Another Sysinternals tool called VMMap shows what types of virtual memory is assigned to a process and its committed memory, which is the virtual memory reserved by the operating system. This tool shows where allocated memory is used with a visual presentation.

VMMap measurements
VMMap shows how the operating system maps physical memory and uses memory in the virtual space to help administrators analyze how applications work with memory resources.

VMMap doesn’t check the hypervisor layer, but it does detail virtual memory use provided by the OS. Combined with other tools that view the hypervisor, VMMap gives a complete picture of the applications’ memory usage.

Another tool called RAMMap is similar to VMMap, but it works at the operating system level rather than the process level. Administrators can use both tools to get a complete picture of how applications are getting and using the memory.

BgInfo puts pertinent information on display

BgInfo is a small Sysinternals utility that displays selected system information on the desktop, such as the machine name, IP address, patch version and storage information.

While it’s not difficult to find these settings, making them more visible can help when you log into multiple VMs in a short amount of time. It’s also helpful to avoid installations on the wrong VM or even rebooting the wrong VM.

StorageCraft update adds converged appliance, data protection

In a move that was hinted at earlier this year, the latest StorageCraft update revamps the OneBlox and ShadowProtect products into the new OneXafe and ShadowXafe. More than just a name change, both products bring significant changes, bringing together primary, secondary and cloud storage, and the means to back them up onto a single platform.

With OneXafe, the StorageCraft update integrates the OneBlox scale-out storage appliance with the company’s backup and data protection software. StorageCraft acquired object storage vendor Exablox in 2017 for its OneBlox platform.

“We’ve taken the technology and the products we bought through the Exablox acquisition, which is mainly the scale-out storage for primary and secondary markets, and tightly integrating that with the data protection technologies from StorageCraft,” said Shridar Subramanian, vice president of marketing and product management at StorageCraft Technology Corp.

OneXafe will come in HDD-equipped 4400-series models, which start at $14,000 for 144 TB, and all-flash 5400-series models, which start at $38,000 for 38 TB. They will be available later this year.

The StorageCraft update revamps ShadowProtect as well, with the new ShadowXafe. This data protection software product is tightly integrated with the company’s existing cloud-based disaster recovery as a service (DRaaS) offering and boasts a near-instant recovery from physical or virtual machines. ShadowXafe’s features also include agentless support for virtual environments, service-level agreement-driven backup policy orchestration, and the ability to recover to dissimilar physical or virtual environments. The ShadowXafe software is currently available.

Although ShadowXafe makes up the data protection component of the total OneXafe package, both products can be purchased independently. ShadowXafe is hardware-agnostic and can be deployed to any system, and OneXafe without ShadowXafe is essentially a OneBlox appliance with hardware upgrades.

Targeting the midsize enterprise, the StorageCraft update was designed to be easy to deploy. “We’ve made something that’s easy to manage and something that does primary, secondary and data protection,” Subramanian said.

With other vendors, IT administrators would have to pick out those three components piecemeal and then figure out how to build a backup infrastructure with them, effectively becoming “pseudo-system integrators,” according to Subramanian. “With our system, they don’t have to worry about any of those things. They can just put these solutions in play. It is a plug-and-play model, and they can grow capacity and protection capabilities as the need arises,” he said.

According to Amita Potnis, research manager at IDC, StorageCraft has had a history of enticing the midsize market with its object storage, which scales better than file-based systems.

“Generally speaking, when using a file-based storage environment, they probably will not have the ability to scale to the extent that an object store does,” she said. “I think having the ability to scale dramatically, and easily, and affordably, it would help midsize customers especially.”

Ctera Networks adds Dell and HPE gateway appliance options

Ctera Networks is aiming to move its file storage services into the enterprise through new partnerships with Dell and Hewlett Packard Enterprise.

The partnerships, launched in June, allow Ctera to bundle its Enterprise File Services Platform on more-powerful servers with greater storage capacity. Ctera previously sold its branded cloud gateway appliances on generic white box hardware at a maximum raw capacity of 32 TB. The new Ctera HC Series Edge Filers include the HC1200 model offering as much as 96 TB, the HC400 with as much as 32 TB and the HC400E at 16 TB on Dell or HPE servers with 3.5-inch SATA HDDs.

The gateway appliances bundle Ctera’s file services that provide users with access to files on premises and transfers colder data to cloud-based, scale-out object storage at the customer site or in public clouds.

The new models include the Petach Tikvah, Israel, company’s first all-flash appliances. The HC1200 is equipped with 3.84 TB SATA SSDs and offers a maximum raw capacity of 46.08 TB. The HC400 tops out at 15.36 TB. The all-flash models use HPE hardware with 2.5-inch read-intensive SSDs that carry a three-year warranty.

Ctera Networks doesn’t sell appliances with a mix of HDDs and SSDs. The HC400 and HC400E are single rack-unit systems with four drive bays, and the HC1200 is a 2U device with 12 drive bays.

“In the past, we had 32 TB of storage, and it would replace a certain size of NAS device. With this one, we can replace a large series of NAS devices with a single device,” Ctera Networks CEO Liran Eshel said.

Ctera HC Series Edge Filers
New Ctera HC Series Edge Filers include Ctera Networks HC1200 (top) and HC400 file storage.

New Ctera Networks appliances enable multiple VMs

The new, more-powerful HC Series Edge Filers will enable customers to run multiple VMware virtual machines (VMs), applications and storage on the same device, Eshel said. The HC Series supports 10 Gigabit Ethernet networking with fiber and copper cabling options.

“Our earlier generation was just a cloud storage gateway. It didn’t do other things,” Eshel said. “With this version, we actually have convergence — multiple applications in the same appliance. Basically, we’re providing top-of-the-line servers with global support.”

The Dell and HPE partnerships will let Ctera Networks offer on-site support within four hours, as opposed to the next-business-day service it provided in the past. Ctera will take the first call, Eshel said, and be responsible for the customer ticket. If it’s a hardware issue, Ctera will dispatch partner-affiliated engineers to address the problem.

Using Dell and HPE servers enables worldwide logistics and support, which is especially helpful for users with global operations.

“It was challenging to do that with white box manufacturing,” Eshel said.

Software-defined storage vendors require these types of partnerships to sell into the enterprise, said Steven Hill, a senior analyst at 451 Research.

“In spite of the increasingly software-based storage model, we find that many customers still prefer to buy their storage as pre-integrated appliances, often based on hardware from their current vendor of choice,” Hill wrote in an e-mail. “This guarantees full hardware compatibility and provides a streamlined path for service and support, as well as compatibility with an existing infrastructure and management platform.”

Cloud object storage options

The Ctera product works with on-premises object storage from Caringo, Cloudian, DataDirect Networks, Dell EMC, Hitachi, HPE, IBM, NetApp, Scality and SwiftStack. It also supports Amazon Web Services, Google Cloud Platform, IBM Cloud, Microsoft Azure, Oracle and Verizon public clouds. Ctera has reseller agreements with HPE and IBM.

Eshel said one multinational customer, WPP, has already rolled out the new appliances in production for use with IBM Cloud.

The list price for the new Ctera HC Series starts at $10,000. Ctera also continues to sell its EC Series appliances on white box hardware. Customers have the option to buy the hardware pre-integrated with the Ctera software or purchase virtual gateway software that they can install on server hypervisors on premises or in Amazon or Azure public clouds.
