What is new in vSphere 6.5 Security?

October 18, 2016 Kim Bottu 0

Data security and data privacy are still becoming more and more important. On the flip side of trying to tighten the security layer is that security is becoming vastly harder to manage. VMware’s vision about security is that it has to be easy to manage. This of course applies to traditional applications  as well as cloud native apps, such as VMware’s Photon. Of course in both cases it is mandatory that the infrastructure hosting data, the data itself and the access to data would be always as secure as possible.  vSphere 6.5 Enhanced Logging For years we have been having issues getting the right logs for auditing out of vCenter and ESXi server logs. For example today, vSphere 5.x and vSphere 6.x […]

vSphere Hosts: Blades vs. Rack-mounted Servers

March 9, 2015 Shady ElMalatawey 2

One of the political-like eternal debates is the debate around vSphere Hosts Form Factor, which to choose: Blade Servers or Rack-mounted Servers. Both technologies are mature and support high computing power and Hardware Vendors offer both of them now equally. In addition, VMware vSphere supports using both of them and puts no limitation on the form factor of the hosts. They’re dominating now over Tower form factor which began to disappear because of its large foot print and high power usage. Confusing to choose between them, right? Long story short, both options have their own Pros and Cons that should be aligned with your (customer) case and your (customer’s) requirements and constraints. In the following table, a summary of the main differences […]

Unable to log in with “root” on vCenter Server Appliance 5.5

February 24, 2015 Shady ElMalatawey 0

Yesterday, I went to a customer for a migration project to vSphere 5.5. After deploying vCenter Server Appliance 5.5 U2d and configuring IP addresses, I logged in with “root” account and default password to begin configuration and I started with adding it to my customer’s AD Domain to adjust its time sync and confirm machine naming and DNS settings. After I added it successfully, I rebooted the vCenter Appliance and once it booted up I tried to log in with “root” and boom, I can’t log in. It threw an error: “Unable to authenticate user. Please try again.” First, I thought I was writing password wrong, but I wasn’t as I found that I could log in using SSH. Then, […]

Virtualizing Microsoft Exchange 2010/2013 on vSphere 5 Best Practices

February 12, 2015 Shady ElMalatawey 1

We’ll talk today about virtualizing Microsoft Exchange on vSphere 5.x platform. Microsoft Exchange is considered the most common messaging system in any business all over the world. From SMB to huge Enterprises and Corporations, they all may use Microsoft Exchange as their messaging and communication system. For most of them, Exchange is considered Tier 0/1 that should be served with highest level of performance and availability. vSphere 5.x is capable of providing such level of performance and availability while reducing Microsoft Exchange footprint with 5x to 10x by consolidating many Exchange roles and nodes on the same physical hardware while providing 100% or more of the required performance. Best practices mentioned here are collected from different sources that are mentioned in […]

Virtualizing Java Enterprise Applications on vSphere 5 Best Practices

February 6, 2015 Shady ElMalatawey 0

Enterprise Software are known to be business-critical and business-oriented software that each company develops its own one to serve their business needs. Today, we gonna talk about Java Enterprise Applications. Java Enterprise Apps are multi-tier Enterprise Software that consists of -generally- from 3 tiers: Web Interface, Application Processing Tier and a Back-end DB. Each tier isn’t a single instance -either physical or virtual-, but each tier consists of a cluster of instances to serve the purpose of the tier. This makes Java Enterprise Applications excellent Virtualization candidates. vSphere 5.x with its enormous features, can deliver the required performance, scalability and availability level for Java Enterprise Applications clusters. With HA, DRS, vMotion and other many features, vSphere Platform can extremely decrease the physical hardware […]

Virtualizing SAP HANA on vSphere 5 Best Practices

February 5, 2015 Shady ElMalatawey 0

Today, we will explore an application that requires high levels of hardware specs to host and highest level of performance, It’s SAP HANA. SAP HANA is one of the most powerful Data Processing software in the world. It’s an in-memory, column-oriented, relational database management system developed and marketed by SAP SE. SAP HANA was supported on vSphere 5.1 for non-production environment and became supported for production in Q2 2014 on vSphere 5.5. Best practices here are gathered from few sources found that are mentioned in References section below. I’ll follow the same schema of my previous posts and relate these best practices to our five Design Qualifiers (AMPRS – Availability, Manageability, Performance, Recoverability and Security) in addition to Scalability. Availability: 1-) Leverage […]

Virtualizing Oracle Databases on vSphere 5 Best Practices

February 3, 2015 Shady ElMalatawey 0

In our next post, we will talk about Oracle Databases as our next candidate of Virtualization. Oracle DBs are known to be heavy duty, Tier 0 or Tier 1 servers that losing it can lead to business disruption significantly. Oracle is a Strategic Partner of VMware. This provides a great support and compatibility of Oracle DBs above or below vSphere Platform. As we’ll see in following sections, Oracle DB is supported as a virtual application above vSphere Platform or as a store for vSphere data used by vCenter Server for example. As Microsoft SQL Servers, Oracle Applications and Database has its own features that are aligned with vSphere features to push Oracle Databases performance, availability and scalability to another level. […]

Virtualizing Microsoft SQL Server 2012/2014 on vSphere 5 Best Practices

January 28, 2015 Shady ElMalatawey 2

Today, we will talk about Microsoft SQL Server Virtualization. SQL Databases have been in our data centers since 1990s carrying TBs of data that are stored and retrieved by many and many of applications. Nowadays, no business application can run without a SQL back-end DB. This leads to a “Spree” of databases in our data centers, pushing Microsoft SQL Server to be one of our most critical applications that spans both production and non-production regions. The latest editions now are Microsoft SQL Server 2012 and 2014. We’ll talk about how to virtualize Microsoft SQL Server using vSphere 5.x platform and how to leverage new SQL Server features, like: Always-on Availability Groups (AAG) and Data Mirorring, to provide the required level […]
