ZFS Readzilla and Logzilla: ZFS ARC & L2ARC and the ZIL & slog

Yesterday I held a presentation about ZFS Readzilla and Logzilla, ZFS ARC and Zil and how it works at the CADAC Day.
You can use readzilla and Logzilla devices in our Sun Storage Unified Storage Systems aka Openstorage to boost the read and write performance.
What's all about it you can read in my presentations ZFS_arc available in english as well as in german, and in both formats: as staroffice/openoffice with-notes-file or as .pdf file.

Update:
I realized that the german pdf link was not working properly, although the syntax was correct - weird. Please use the below link to access the german .pdf document named ZFS_arc_dt.pdf.

RAID-Z - What is it and what its benefit ??


Moin Moin folks,

- english Version below in orange - 

oft werde ich von meinen Kunden gefragt: "Was ist eigentlich RAIDZ und wie kann es Redundanz und die Integritaet der Daten garantieren?

Und ich beginne einen Email zu verfassen und beschreibe die Funktionalitaeten von ZFS ( self-healing, checksumming), ich erzaehle von zpools, Spiegeln des zpools und Einrichten von RAIDZ.

Und ich verweise auf die zahlreichen Blog Eintr├Ąge auf blogs.sun.com.

Oh - sagt der Kunde, das ist ja alles in englisch, gibt es denn da nichts in deutsch.

Nein, musste ich bisher sagen.. bisher.

Nun habe ich mich mal hingesetzt und ein Dokument in deutsch verfasst: 

English Version 

often, I am asked by my german customers, what is RAID-Z and how does it guarantee data integrity and redundancy and I start to write an email describing the features of ZFS: self healing, checksumming, and this in combination with mirrored zpools or RAID-Z zpools.

And I refer to the links of blogs.sun.com.

Uh - the customers moan, - but this is in english! Aren't there any documents in german?

No, until now

Here is my whitepaper about traditional RAID-Systems ( for comparision and for general information ) and RAID-Z and it's benefits against RAID5.

If you have comments, suggestions etc. please send me an email.

Have a nice day
Claudia
