Jboss AS 5 GA release date

24 November 2008

People have been wondering for some time about the release date of Jboss AS 5. As many of you know, Jboss 5 has been in development for quite some time and its release has been highly anticipated. Arguably, Jboss is one of the most important, if not -the- most important Java EE implementation. The fact that an official release of version 5 of this spec has been so long overdue, has been painful. Of course, Jboss 4.2.x supports most of the Java EE 5 stuff, but it’s just not the Real Thing.

The importance of Jboss AS is due to a number of reasons. Of course there are other Java EE 5 implementations out there, but the number of offerings seem to be declining. On the commercial side of the fence there’s basically IBM’s Websphere and Oracle’s OC4J, and on the open source side there’s Glassfish, Geronimo and Jboss AS 5. For many people, a closed source, commercial Java EE implementation seems to be little attractive. This leaves us basically with only 3 options for the moment. Geronimo may be nice, but nobody seems to be using this. Glassfish should maybe be the default choice (afterall, the Sun Java SE implementation is typically the default choice for many too), but has two main problems:

  1. It can’t be configured.
  2. It doesn’t offer any services.

This basically leaves Jboss AS 5 as the only choice, it it weren’t for the fact that it was always still in beta or in rc. In a way, this left a kind of void in the Java EE world (unless of course configuration and services don’t matter to you, then I suppose Glassfish would be perfectly fine).

Previously, Jboss AS 5 had been announced for february 2008 (see Where is JBossAS GA 5), but this seemed to be too optimistic. A major milestone was reached when Jboss AS 5 RC2 was officially EE 5 certified. A careful guess for the GA release date was then made for early November 2008 (see JBoss AS is now EE5 certified!).

Today however, a definite date has been given by Project Lead Dimitris Andreadis:

December 2008!

Building the new battleship Mtron

20 November 2008

A while back I stumbled upon the legendary article; Battleship Mtron, the absurdly fast RAID array build with 9 Mtron SSDs on a blazingly fast Areca ARC-1231ML, sporting an amazing 800 MHz Intel IOP341.

It was the fastest thing on the planet. Period.

A year has passed since then. At M4N we have been experimenting with an SSD setup consisting of 4 Mtron 7000 SSDs on a development server. After some extensive benchmarking, it appeared that in nearly all situations the IO power of these beasts is far superior to that of the traditional hard disk. A decision was made to order a bunch of SSDs to be placed in multiple servers. 12 of those arrived today, along with 2 Arceca ARC-1680IX-12’s equipped with a whopping 4GB of cache each and the fast 1.2Ghz IOP348.

Seeing all that hardware together however made us think. What if we… assemble it all together in -1- massive storage array? 12 Mtron 7500’s on 2 Arceca 1680’s (6 per controller), combining the power of the RAID sets of both Areca’s into 1 single volume using software RAID. What will be the performance of that?

Stay tuned for our upcoming benchmark reports!
