ssd iometer follow-up tests v09.31.12.txt

author: Randy J. Cress date:
I needed to followup on my test results with the Iomega IX4-200d SSD iometer testing to see what could be going on.. see http://blog.randyjcress.com/2009/12/howtokillanix4-200dwithssdiometertests1.html for the first set of numbers, but I will duplicate them here for comparision purposes.

The main goal was to keep the (4) Kingston SSDNow V-Series 128GB SSD Drives in a hardware RAID10 array throughout the testing process. I will drop the millisecond avg and max because it matters, but isn't the focal point..

Group_A: Iomega IX4-200d RAID10 SSD drives, 1Gb/s iSCSI to VMware ESX 4.0.0 bld 208167 with Windows Server 2008 x86 VM.

Group_B: Iomega IX4-200d RAID5 1TB mechanical disk, 1Gb/s iSCSI to VMware ESX 4.0.0 bld 208167 with Windows Server 2003 VM - http://www.gabesvirtualworld.com/?p=909

Group_C: RAID10 SSD Drives with LSI Logic PCIe MegaRAID SAS 8204ELP on Windows 7 Enterprise x64 direct IOMeter tests on the SYSTEM volume (C:)

Group_D: RAID10 SSD Drives with LSI Logic PCIi MegaRAID SAS8204ELP on Windows 7 Enterprise x84 with StarWind iSCSI Free Target with 1Gb/s Broadcom network connection

xenserver update v08.24.08.txt

author: Randy J. Cress date:
ok, while starting to building the new xenapp 4.5 farm (knowing 5.0 is right around the corner) I've decided not to scrap XenServer Enterprise and give the latest beta with NIC bonding and SAN FC multipathing a shot for our XenApp VMs along with Citrix PVS 5.0 (btw, Dell Flexible Computing has updated their download site) http://www.dell.com/flexiblecomputing Right now I don't have a problem saying we'll use XenCenter to manage the XenApp hosts running XenServer since the PVS servers are running in VMware ESX 3.5 along with the rest of the backend infrastructure.. I thought I would be stuck with no room for any shared storage since the SAN is fully carved with vmfs3 volumes and place from a Xen LVM but with Provisioning Server I can just stream the vDisks to the XenApp servers without a need for any hdd being visible to those VMs. On a side note, the VNC-based implementation for the console in XenCenter is not so cool.. it "feels" like VNC versus a guest run...

using vlc to create a web-based vod library v07.18.11.txt

author: Randy J. Cress date:
There are many reasons why you would want to create Video-on-Demand library with a web interface.. training videos, past security recordings, news clips, etc.. My reason was different this weekend.. it is starting to become difficult to weed through all of the DVDs with children's show for my daughter. While she has no problems sorting through the DVDs and picking out a show to watch if we label it correctly, it still is time consuming and over time the discs become worn and damaged. I needed a way to create a video on demand library and have it easy to use for her. Since she can navigate around on the web just fine, I wanted to make it as simple as YouTube for point and click access to her shows. Enter VideoLAN VLC Player/Server Now we can do the following: TV -> DVR -> DVD -> VLC -> RTSP -> PC = Happy Child The quick and dirty approach for serving DVDs over wired/wireless for VOD via the web: Download and install VLC 0.8.6c here . Copy the entire VIDEO...

an outlook for security improvements in 2019 v18.12.24.txt

author: date:
As we wrap up 2018, my news feeds and various email inboxes are littered with security breaches, security vendor hardware, software and training solutions. All citing an infamous undertone of someone that clicked on a bad link ultimately ending in unwanted code execution that led to more code execution and finally data exfiltration. I am taken aback by our current ecosystem of general purpose operating systems and their bloated sense of "purpose".  When is the last time you purchased multi-layer security solutions for your best of breed gaming platforms in your home network environment?  How often do you bludgeon your children's minds with security awareness training when downloading skins, avatars, games and expansion packs from the respective console gaming platforms online stores?  Do you recognize the computational power, network connectivity and deeply connected devices in your most personal home networks linked to video cameras, door locks and vast array of se...
