Oracle Solaris Operating System Interview Questions

Oracle Solaris is a proprietary Unix operating system originally developed by Sun Microsystems earlier SunOS in 1993. In 2010, after the Sun acquisition by Oracle, it was renamed Oracle Solaris. Solaris is known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace, ZFS and Time Slider.  Solaris supports SPARC and x86-64 workstations and servers from Oracle and other vendors.

Explain Raid0, Raid1, Raid3 in Oracle Solaris Operating System interview questions?


RAID 0 Concatenation/Striping

RAID 1 Mirroring

RAID 5-Striped array with rotating parity.

  • Concatenation: Concatenation is joining of two or more disk slices to add up the disk space. Concatenation is serial in nature i.e. sequential data operations are performed serially on first disk then second disk and so on. Due to serial nature new slices can be added up without having to take the backup of entire concatenated volume, adding slice and restoring backup.
  • Striping: Spreading of data over multiple disk drives mainly to enhance the performance by distributing data in alternating chunks – 16 k interleave across the stripes. Sequential data operations are performed in parallel on all the stripes by reading/writing 16k data blocks alternatively form the disk stripes.
  • Mirroring: Mirroring provides data redundancy by simultaneously writing data on to two sub mirrors of a mirrored device. A submirror can be a stripe or concatenated volume and a mirror can have three mirrors. Main concern here is that a mirror needs as much as the volume to be mirrored.
  • RAID 5: RAID 5 provides data redundancy and advantage of striping and uses less space than mirroring. A RAID 5 is made up of at least three disks, which are striped with parity information written alternately on all the disks. In case of a single disk failure the data can be rebuild using the parity information from the remaining disks.

Latest 3rd generation Xeon Scalable processor called Ice Lake

Latest 3rd generation Xeon Scalable processor called Ice Lake


The 10 nanometer-based CPU is delivering up to 40 cores per processor.

The processors also add Intel SGX (Software Guard Extensions) for built-in security, as well as Intel Crypto Acceleration. It includes Intel’s DL Boost for AI acceleration.

  • AI acceleration: 

    Intel says that with hardware and software optimizations, Ice Lake delivers 74 percent faster AI performance compared with the prior generation. Compared to the third-generation AMD Epyc 7763, Intel says the platform delivers up to 1.5 times higher performance across a broad mix of 20 popular AI workloads. Compared to the Nvidia A100 GPU, it says it delivers up to 1.3 times higher performance on a broad mix of 20 popular AI workloads.

  • Built-in security:

    Intel SGX, and security has the technology can protect as much as 1 terabyte of code and data in private memory areas called enclaves.

    Ice Lake chips also feature cryptographic acceleration that promises to let the chip deliver both security and performance.

  • Intel Ice Lake vs. Intel Cascade Lake

Some of the key differences between Intel’s new 3rd gen Xeon CPUs with Intel’s 2nd gen Xeon Scalable processors. The below table highlights the processor architecture, cache latencies, memory controller, memory latency, and capacity.

Latency Intel Xeon Platinum 8380 Processor (Ice Lake) Intel Xeon Platinum 8280 Processor (Cascade Lake)
L1 hit cache, cycles 5 4
L2 hit cache, cycles 14 14
L3 hit cache (same socket) 21.7 20.2
L3 hit cache (remote socket) 118 180
Memory Controller On die – 8 ch On Die – 6ch

Max DIMM Capability

2 DPC 3200/2933/2666 New: PMem (SKU dependent) runs at memory channel speed 1 DPC 2933/2 DPC 2666 (SKU dependent)
DRAM read latency local socket 85 81
DRAM read latency remote socket 139 138
Max Memory Capacity per Socket 6TB (DDR+PMem). 4TB (DDR) 4.5 TB (DDR+PMem). 3TB (DDR)


The platform supports up to six terabytes of system memory per socket, up to eight channels of DDR4-3200 memory per socket, and up to 64 lanes of PCIe Gen4 per socket.

Ice Lake delivers an average 46 percent performance increase on popular data center workloads


Intel produces network-optimized “N-SKUs” to support diverse network environments. The new processors deliver on average up to 62 percent more performance on a range of broadly-deployed network and 5G workloads over the prior generation, Intel says. More than 15 major telecom equipment manufacturers and communications service providers are readying POCs and networking deployments with Ice Lake.


Ice Lake delivers up to 1.56 times more AI inference performance for image classification than the prior generations, Intel says. This makes it suitable for AI, complex image or video analytics, and consolidated workloads at the edge.

Intel Optane SSD Storage:

Intel increased the capacity of the drive which started at 375GB, tops at 1.5TB. Optane SSDs perfect companion for slower media. we primarily designed for endurance and frequently used in a two-tier architecture. Optane SSDs are often set up to absorb all of the writes in a system, protecting larger, slower media behind it. These can be QLC SSDs for instance, that perform well for read-heavy workloads, but don’t have much endurance or write performance.

vSAN, Azure HCI, StorONE, and many others are well adept at making multi-tier work well.

PMem: Intel Optane Persistent Memory

A way to bridge the gap between volatile DRAM and high-performance SSDs. PMem 200 is quoted to deliver 32% more memory bandwidth than Gen1. New modules are optimized for the new 3rd Gen Intel Xeon Scalable Processors, making the combination, with Intel SSDs.

In the memory bandwidth throughput, with PMem 200 picking up 3,200 MT/s support.

Core count starts at 16 cores and goes up to 40. With the first PMem, users could add 3TB of PMem for a total memory per socket of 4.5TB, now the total is 6TB per socket, with 4TB of PMem 200 being added. The maximum thermal design power dropped from 18W to 15W. And the newest persistent memory comes with eADR, extended Asynchronous DRAM Refresh.

The MemVerge Memory Machine management interface can help administrators through a number of use cases:

Crash recovery:

The snapshot GUI is used to quickly bring back the database and/or troubleshoot the cause. The database log and Memory Machine Dashboard data determine the time of the crash, allowing the admin to select and restore a snapshot that is closest to the crash time. Developers can then use that restored instance for debugging.

Accelerating Animation & VFX with Memory DVR:


Artists want to explore different options on a base Maya scene. They load the base scene, apply the changes, and save it as a different project. They can save many separate scenes, but to show these options they must be repetitively reloaded, which takes a long time.

With Memory DVR functionality, load a base scene once, take a snapshot as the basic snapshot, then apply changes and take another snapshot. To apply a different effect, simply restore the snapshot, edit, and take another snapshot. The restore speed of in-memory snapshots is a few seconds compared to minutes for reloading scenes from storage.

Accelerating Genomic Analytics with Memory DVR:

Scientists want to experiment with a machine learning algorithm using different parameter settings. They load the data, set the parameter, run the algorithm, and check out the results. if the results are not good, the data is reloaded, a different set of parameters is applied, and the algorithm is run again.

With Memory DVR functionality, load the data once and take a snapshot. From that point on, if the results are not good, restore the base data and another run with new parameters is done in seconds.

Intel Agilex FPGAs that leverage PCIe Gen4.

Intel Agilex FPGA family leverages heterogeneous 3D system-in-package (SiP) technology to integrate Intel’s first FPGA fabric built on 10nm process technology and 2nd Gen Intel Hyperflex FPGA Architecture to deliver up to 40% higher performance1 or up to 40% lower power1 for applications in Data Center, Networking, and Edge compute.

Azure Automanage

Support for on-prem Windows Server in Azure Automanage. Means you can now do rebootless patching of managed machines with Azure Automanage and Windows Server

Windows Admin Center Version 2103

Windows Admin Center is the new way to manage Windows Server. The old RSAT tools still available

Windows Admin Center 2103 functionality includes:

  • Public Preview of Windows Admin Center running in Microsoft Azure
  • Automatic Updates for WAC and its Extensions
  • Support for Outbound Proxies
  • Windows Event Viewer Overhaul

SERVER Core Container

Windows Server Core container images are 40% smaller and startup times to Windows PowerShell are 30-45% faster.

Windows Server Core container images are used for

  • scaling apps,
  • continuous integration and
  • continuous delivery (CI/CD),
  • situations where images are pulled without using a Docker image cache or where faster startup times are required.

Container Images

To reduce Server Core container image sizes by including a smaller set of NGEN images by decreasing image size and maintaining startup performance

NGEN images are a series of precompiled .NET native images that are generated using a tool called Ngen.exe to improve startup performance. NGEN was the culprit for increased image size.

To achieve its goals for the Windows Server Core base image layer, Microsoft made the following changes:

  • Included a serviced copy of .NET Framework 4.8.
  • Removed all NGEN images, except for mscorlib.dll, System.dll and System.Core.dll (32-bit and 64-bit).

In the .NET Framework runtime image layer, the changes are as follows:

  • Included NGEN assemblies used by Windows PowerShell and ASP.NET only.
  • Included only NGEN 64-bit assemblies.

Better application compatibility

Windows Server 2019: Brought the optional Server Core ‘App Compatibility’ Feature on Demand. It lets applications run in Server Core that would normally require the desktop experience to be installed.

Windows Server 2022: Allow organizations to run globally scalable apps with virtualized time zones, and even run apps that depend on Active Directory (AD) without joining the container hosts to the domain.

Group Managed Service Accounts for Active Directory support

Containers can’t be joined to AD, but they can still use AD domain accounts to support authentication. A Windows container can run with a group Managed Service Account (gMSA). gMSAs let multiple computers share an identity without needing to know its password.

When a container is configured to run using a gMSA, the container host gets the gMSA password from Active Directory and passes it to the container. The container then uses the gMSA credential when its computer account (SYSTEM) needs to access network resources.

Virtualized time zones

An update in Microsoft Server 2022 will allow you to set the time zone in container instances using the tzutil command line tool, by setting the virtual registry key, or by specifying the time zone using a Docker/AKS (Azure Kubernetes Service) argument.

Windows Admin Center container tool

The Windows Admin Center (WAC) container extension is now a fully paid-up member of the team and it is available as an out-of-the-box tool. The container tool lets you get Windows and Linux containers up and running quickly. Also another option to migrate legacy Windows Server ASP.NET, WebDeploy, .NET, and MSI applications to the Azure container registry, allowing you deploy apps in Azure and Azure Stack HCI.

Container tool in Windows Admin Center (WAC)

The container tool in WAC lets administrators containerize existing applications by answering a few simple questions. The tool then generates the necessary Docker file with instructions on how to create the container image. Once the Docker file has been generated, you can either run the image locally or push it to an external container registry.

Deploy consistent network policy with Calico across hybrid Kubernetes clusters

Calico is an open-source container networking solution created by Tigera. Kubernetes doesn’t manage network connectivity between containers. Container Networking Interface (CNI) plugins, like Calico, enable full network connectivity between cluster nodes. But full network connectivity between nodes can introduce security risks. Tools like Calico use the Kubernates NetworkPolicy API to apply consistent network policy.

A problem with Windows worker node support in Kubernetes is that Calico, one of the most popular network policy tools, doesn’t support Windows. That is until now. With the release of Calico version 3.16, Windows containers can be deployed and secured in Azure, other cloud providers, and on-premises using the network components in Windows Server and Calico network policy. Furthermore, you can take the containers you deployed in AKS and deploy them in Azure Stack HCI. They will just work, be fully compliant, and can be managed from the cloud using Azure Arc.

 If you’re interested in trying the new version of Windows Admin Center, you can call us.
