Replacement Schedule

September 2007: Examination of proposals. Open bid. October 2007 - : System Design with the vendor

Functions on the new system Intermediate system Data transfer Application transition

October 2007 - : Delivery and installation of the new hardware

December 2007 - : New system test January 2008 - : Gradual termination of the current system

and transition either to the intermediate system or the new system.

February 29, 2008: Stop operation of the current system March 1, 2008: Start operation of the new system

Due to a serious restructuring of the budget in NAOJ, our computer system will be drastically downsized and functions for observation and data archive are prioritized.

Great cut of computer budget for NAOJ as well as for Subaru.

But, computation performance of each workstation (ows, ana…) will be upgraded.

STARS new version has its own copy area = STN account not necessary to copy data from STARS

STARS new version needs one less copy of files.

No longer. STN account policy will be reviewed.

Only if observers need to get data outside STN.

More and more observers copy data from ana to their own computers on site, that does not need either STARS or STN account.

これから (S07B 以降 ) 観測される方へ ; 観測所のストレージ領域にデータを置かず、観測の都度お持ち

帰りください。 グループ領域 (/grpNN):

バックアップの円滑な遂行のため、アクセス制限を実施しています。新規の書き込みは 2007 年 11 月 30 日をめどに終了いたします。

ハードディスク上の領域( /home , /scr/local , /ksdatNN , Web/ メールサーバ上のデータなど) : 2008 年 1 月中に運用を停止いたします。 /home , /scr/local ,/ksdatNN のデータは新システムには移行されませんので、ご自身でバックアップをお願いします。 Web/ メールサーバ上のデータは新システムにアカウントが移行するユーザに関しては、計算機部門で新システムに移行します。ただし、重要なデータはユーザでのバックアップをお願いします。

スクラッチ領域 (/scrNN): 2007 年 12 月 31 日をめどに新規・更新割り当てを廃止します。

すでにデータをため込んでいる方は;1. グループ領域 (/grpNN) 内のデータ

引き取りたいファイルを特定し、ハワイ観測所に通知してください。

ハワイ観測所がファイルを一時格納場所に移した後、その一時格納場所にあるファイルがただしいデータであることをすみやかに確認してください。

最終的なデータの格納場所を用意し、データを引き取ってください。

必要なデータをテープにコピーして送付することもできます。2. それ以外の領域 (/ksdat, /scr/local, /home など ) のデー

タ できるだけ今年中に必要なデータをバックアップしてください。 最終的なデータの格納場所を用意し、データを引き取ってくだ

さい。 必要なデータをテープにコピーして送付することもできます。
