Over the coming month I will be architecting, building and testing a modular, high performance SSD-only storage solution. I’ll be documenting my progress / findings along the way and open sourcing all the information as a public guide. With recent price drops and durability improvements in solid state storage now is better time than any to ditch those old magnets. Modular server manufacturers such as SuperMicro have spent large on R&D thanks to the ever growing requirements from cloud vendors that utilise their hardware. The State Of Enterprise StorageCompanies often settle for off-the-shelf large name storage products from companies based on several, often misguided assumptions:

Further to my earlier post on XenServer storage performance with regards to directly attaching storage from the host, I have been analysing the performance of various SSD storage options. I have attached a HP DS2220sb storage blade to an existing server blade and compared performance with 4 and 6 SSD RAID-10 to our existing iSCSI SANs. While the P420i RAID controller in the DS2220sb is clearly saturated and unable to provide throughput much over 1,100MB/s - the IOP/s available to PostgreSQL are still a very considerably performance improvement over our P4530 SAN - in fact, 6 SSD’s result in a 39.

IntroAt Infoxchange we use XenServer as our Virtualisation of choice. There are many reasons for this including: Open Source. Offers greater performance than VMware. Affordability (it’s free unless you purchase support). Proven backend Xen is very reliable. Reliable cross-host migrations of VMs. The XenCentre client, (although having to run in a Windows VM) is quick and simple to use. Upgrades and patches have proven to be more reliable than VMware. OpenStack while interesting, is not yet reliable or streamlined enough for our small team of 4 to implement and manage. XenServer Storage & Filesystems Unfortunately the downside to XenServer is that it’s underlying OS is quite old.

Reprogram BMW after doing Automatic to Manual ConversionBased on my E36 328is experience, written in 2010. AssumptionsThis guide assumes the following: You have programmed a BMW ECU/DME before using DIS or similar. You are taking all the necessary safety precautions. (Fully charged battery etc…) You have DIS working (We used EasyDIS 1.0, Base 44) You have Ediabas (INPA, NCS Expert, IFH Serve) installed and working. You’re able to read between the lines of our crappy document, some steps may differ slightly and our wording may be somewhat imprecise.
