News_manstealingdataRemember the article that we posted a couple of weeks ago stating that one thing that Anonymous has done is highlight security concerns that corporations would rather keep hidden? Well it turns out that the recent hack on the China Electronics Import & Export Corp (CEIEC) through an outsourced email provider sina.com was all about highlighting security. We had said more than once that the outsourcing of information into the cloud creates a security hole that is miles wide. Still we see this happening more and more as it becomes “cost effective” to allow someone else to deal with security.

DecryptedTech's new Enterprise Testing Lab

supercomputersDecryptedTech is now moving into Enterprise class testing. To accomplish this we have built a small Enterprise class network in our lab complete with two iSCSI SANs , TWO NAS Devices, multiple Gigabit Switches, and two ESX Hosts with Multiple VMs to keep things interesting.  We will begin testing Enterprise class hardware and Software. We will be looking at these products with an eye on how the technology differs from the average consumer class products as well as how this technology will benefit the consumer as it trickles down to their market space.  We do have our first product in the lab right now, but before we kick that off let’s talk about the new DecryptedTech Enterprise class Lab in detail.

The Switches -
The backbone of our lab consists of five Gigabit Switches. Two of these are from TRENDNet TEG-160WS and the TEG-240WS. Both of these are Web Smart Managed switches and have 2GB trunks setup between the two for faster switching between them. Next we have a TRENDNet TPE-80WS POE (Power over Ethernet) 8 Port Gigabit switch which offers quite a bit more controls than the TEG line and is our master switch for the RSTP (Rapid Spanning Tree Protocol ) topology ion place. Our second vendor in the lab is NETGEAR, they have provided us with their ProSafe GS110TP POE 10 port Gigabit Switch (two of these ports are fiber uplink) and a GS108T 8 Port Gigabit Switch. As we mentioned the switches are part of an RSTP topology and each one has different components attached to ensure that the loads is distributed across the network backbone.

The Storage -
Our Lab has three NAS devices one of which is fully iSCSI capable (and works with VMWare) the two non-iSCSI NAS devices are the Seagate Black Armour 440 and a Thecus 5200 Pro. The Thecus 5200 Pro has 3TB of space and serves as an indirect file server while the BA-440 has 4TB and acts as a media storage server and backup target. The last NAS on the list is a Synology DS 201, this has a full 1TB of space and holds image files used for deployment of VMs and the installation of software into the virtual environment.
storage
The last storage box we are rather proud to have. It is a custom built NAS/SAN with an AMD Phenom II x4 910e 4GB of memory on the Minix 890GX MiniITX motherboard and a 250GB OS Drive. For the OS we dropped in Windows 2008 R2 Storage Server. Of course that is not the thing that we are most proud of. For the actual storage we went with 4 Seagate 2TB Constellation ES Nearline SAS 2.0 drives (ST32000444SS) running in RAID 5 on an LSI MegaRAID SAS 8708EM2 SAS 6GB/s PCIe controller. It is this device with its two teamed NICs that provides the central iSCSI based storage for our VMWare cluster.

The VMWare Cluster -
To make sure that we covered all of our bases we built two VMware ESX Hosts for a single cluster; one of them with Intel Xeons and the other featuring AMD Magny Cours CPUs. Both of these systems have Kingston Server Premier Memory installed (128GB between the two systems).  The motherboards in each are from Asus and represent the mid-range of their server line up.
The Intel System specs are as follows;

2x Intel Xeon L5530 2.4GHz CPUs
48GB of Kingston Server Premier RAM (6 x8GB)
2x Kingston SSD Now 128GB drives in RAID 1 (for the ESX Host Software)
Asus Z8NA-D6 motherboard
Cooler Master UCP 1100 Power Supply


The AMD half of the Cluster looks like this
2x AMD Opteron 6176 SE CPUs (12 Cores each for 24 physical cores)
92GB of memory (80GB Kingston Server Premier 10 x 8GB and 12GB Kingston Value Select Server memory 6 x 2GB)
2 x Seagate 500 GB Savio II SAS 2.0 Drives in RAID 1
Asus KGPE-D16 Motherboard
Cooler Master UCP 1100 Power Supply

The cluster is running VMMware ESX 4.1 (moving to 5.0 soon) and currently hosts 30 Virtual Machines all stored on our Custom Built NAS/SAN. Not all of these systems are powered on 24/7 (my power bill would be outrageous) but they are all on and operational when we have hardware in the lab that needs testing. Under normal conditions about 7 servers are live. These include an exchange cluster (Database Availability Group), a SQL server and a virtualized domain controller. Some of the other servers that run when under testing conditions are, two additional SQL servers (SharePoint and CRM) a two node SharePoint farm, a Xen Desktop test setup with three desktops, a webserver with a full copy of DecryptedTech on it)  and virtualized Windows 2008 R2 domain controller.  We feel this should be able to simulate the load of a fairly average business network.
Vmware
In addition to the virtual systems there is a standalone Domain Controller (Windows 2008 R2) and a complete Microsoft Forefront Treat Management Gateway to control external access to the test environment.

In all the testing lab has taken a giant leap forward and we hope to be able to bring you some in-depth reviews of  hardware and software that while outside the average consumer range will give you a glimpse of what will be coming down the road for the consumer market in the not so distant future.

VMware reinvents the Wheel

AppBlastIn stunning news VMware announced the reinvention of the wheel at the VMware World Conference in Las Vegas. They showed of their new “wheel” which will run slower and have a greater potential for security risks than the older wheel, but they feel that this is the way things are going to be in the future.

Of course the thing that VMware was showing off was not the wheel it was VMware’s Project AppBlast, an updated Horizon Application Manager (which now allows Windows Applications) and a new technology called ThinApp Factory. The theme was the “Post-PC Era” with CTO Steve Herrod saying such catch phrases as “the world has changed” and other nonsense considering the fact that Citrix has been out for more than 10 years and has never managed to push the PC to extinction.

The three technologies that VMware showcased today are not really new, Citrix has XenApp and even Microsoft has products that will allow you to serve up single applications to users. True the Microsoft product will not let you push out to anything other than Windows based systems but Xen can push to the iOS and even to Android in many cases. Xen also has a web interface that allows you to pick and choose the applications you want to run which are run in secured memory spaces on the client system.
We have tinkered with XenApp and XenDesktop on more than a few occasions and it is more than functional with plenty of support behind it.

So, while the new Applications from VMware are interesting they are far from revolutionary and with their expensive licensing scheme you can pretty much bet they will be pricing out of the reach of most companies.
