Installing and configuring Microsoft Forefront TMG for secure OWA access

In this document, we'll look at one of the most common installations when deploying a Microsoft Exchange Server installation 2010 e ensure your connectivity from the outside through OWA access (or the necessary services) via a TMG host on the DMZ network. We will perform the installation of Microsoft Forefront TMG (Threat Management Gateway) An old ISA Server on a DMZ computer that will only be connected via HTTPS from the Internet, and the server will only connect to the Exchange server with the HUB role (or CAS array).

Using VMware vMA

In this document, we'll look at the VMware virtual appliance called VMware Management Assistance (VMware vMA), is based on a CentOS distribution 5.2 with vCLI, CIM, Java JRE, vSphere SDK for Perl and vSphere SDK for Java, is a script-based management appliance for our virtual environment.. VMware vMA is a great utility to replace the Service Console and be able to manage our ESXi or vCenter hosts more easily and centrally through scripts/tasks, We can configure it as a log server, Backup, ESX distribution via PXE…

Booting HP Firmware Maintenance or HP SmartStart CDs with a USB flash drive

I've been wanting to post this post for a long time, something simple like the previous one but many times we find ourselves (for savings issues) HP servers without CD drive, so before installing the operating system we need to update the firmware of all the components of the server with the HP Firmware Maintenance CD and later with the HP SmartStart CD prepare the boot, install HP utilities and drivers on the machine itself. In the case of not having a server with a CD drive, we can with an HP utility dump them into an external USB drive or a pen drive.

Enabling Jumbo frames in VMware environments

An essential feature that we should always leave configured when working with gigabit networks is to modify the MTU value (Maximum Transfer Unit – Maximum Transfer Unit) What is the size (in bytes) of the largest data unit you can send with IP, by default, LAN networks use an MTU of 1500 bytes. On VMware and all devices that make up the gigabit ethernet network (typically the iSCSI storage network) its value must be raised to 9000 bytes, We should enable it in the storage cabin, on the switch (Some switches have it enabled by default), on VMware ESX hosts / VMware ESXi (vSwitch & Port Group) and at the NIC level on equipment that is directly connected. All this in order to take advantage of the gigabit network and be able to send larger packets.
