Hand-on - EMC VNX2 - Multicore Cache

VNX2, Multicore Cache and Multicore FAST Cache. The first of these is Multicore Cache. The Multicore Cache feature provided in VNX2 uses the System Memory for Cache. It introduces the following changes:

•  Completely multicore scalable

•  Dynamic cache that automatically allocates read/write cache

•  High/Low Watermarks have been removed

•  Cache page size is now locked at 8KB

•  Flushing has been changed from forced to predicted

•  Write cache can be enabled/disabled at the array or Classic LUN level

•  Proactively cleans pages during times of low activity, leaving clean pages in cache

• Note that the High/Low Watermarks, write cache size, and page size options have been removed. The system will dynamically allocate cache for reads/writes as necessary and the cache now has a fixed page size of 8KB. You can also see the Read/Write Cache Hit Ratios and Dirty Pages (MB) here.

• Note that the read cache is always enabled, and write cache is enabled by default. Your numbers may be different than those shown below.
  
  
  
  
  
   FAST Cache
   Multicore FAST Cache serves as a high-capacity secondary cache to Multicore Cache you viewed in the SP Cac he tab. Flash drives positioned between the storage processor’s DRAM-based primary cache and hard disk drives form this cache and provide improved access times and higher I/O rates. The Flash drives no longer need to be dedicated to specific applications.
  FAST Cache provides a much larger, scalable cache by using Flash drives that provides very large capacities as compared to DRAM. VNX2

Oracle Server - SPARC M10 - Install Solaris

Unless you intend using the pre-installed disk image on each PPAR there are several possible methods for installing the PPARs including:

• Install each PPAR from Solaris DVD using a USB local drive.The drive must be connected to the front of a BB – see MOS Document ID 1553734.1.

• Install Solaris 10 PPAR using an install server (e.g. via JET). This requires the availability of an install server provided by customer or an engineer's laptop (in those countries where laptops are used as install servers AND the Customer permits introduction of a laptop into the data center).

• Install Solaris 11 PPAR using public or local Solaris repository.

1.  Pre-installed disk image
Standard installations carried out by manufacturing are as follows:

•  Solaris 11.1 will have been loaded.

•  ZFS root file system will be default.

•  The on-board RAID (if available) will not be active.

•  The system will have been patched and configured according to EIS methodology

•  Before leaving the factory, the system will have been “sys-unconfig'd” and the SPset back to defaults.

If you have set up a RAID configuration for the boot disk the pre-installed image
will be lost.
2. Booting from an External DVD

The below example is from a M10-4S with 4 building blocks and the external dvd is being attached to BB#3 which is assigned to LSB03.

•     Plug the external DVD player into the USB port on the front of the M10 machine.

•     Power the DVD player on.

•     Power on the server, or type 'reset-all'  at the OBP  prompt

•     For this example the DVD is connected to the front USB port of BB#03 which is LSB03.  Look at the 'show-devs' output and look for a line similar to this:

            /pci@9800/pci@4/pci@0/pci@1/pci@0/usb@4,1/hub@2
    (See Doc Id. 1543194.1 for more M10 device path information)

If you don't see the string "disk" at the end, the DVD play is not properly attached and powered on.
Correct:
/pci@9800/pci@4/pci@0/pci@1/pci@0/usb@4,1/hub@2/storage@1/disk
DVD Not connected:
/pci@9800/pci@4/pci@0/pci@1/pci@0/usb@4,1/hub@2/storage@1

Then to boot type:
boot /pci@9800/pci@4/pci@0/pci@1/pci@0/usb@4,1/hub@2/storage@1/disk

VMware Horizon™ with View™ - Architecture

View Connection Server

• View Connection Server streamlines the management, provisioning, and deployment of virtual desktops. As an administrator, you can centrally manage thousands of virtual desktops from a single console. End users connect through View Connection Server to securely and easily access their personalized virtual desktops. View Connection Server acts as a broker for client connections by authenticating and directing incoming user desktop requests.

View Security Server

• A View security server is an instance of View Connection Server that adds an additional layer of security between the Internet and your internal network. Outside the corporate firewall, in the DMZ, you can install and configure View Connection Server as a View security server. Security servers in the DMZ communicate with View Connection Servers inside the corporate firewall. Security servers ensure that the only remote desktop traffic that can enter the corporate data center is traffic on behalf of a strongly authenticated user. Users can only access the desktop resources for which they are authorized.

View Composer Server

• View Composer Server is an optional service that enables you to manage pools of “like” desktops, called linkedclone desktops, by creating master images that share a common virtual disk. Linked-clone desktop images are one or more copies of a parent virtual machine that share the virtual disks of the parent, but which operate as individual virtual machines. Linked-clone desktop images can optimize your use of storage space and facilitate updates. You can make changes to a single master image through the vSphere Client. These changes trigger View Composer Server to apply the updates to all cloned user desktops that are linked to that master image, without affecting users’ settings or persona data.

1. View Components
