General fund
The level of funding planned for 2008 was:
- According to the RHIC mid-term strategic planning for 2006-2011 document, the budget for 2008 was projected to be 2140 k$ (table 7-2) with a note that and additional 2 M $ additional would be needed between FY08 and FY10 (to accommodate for network infrastructure, storage robotics and silo expansion and general infrastructure changes)
- The budget planned for FY08 in FY07 was 2.5 M$, accounting for recovering by 0.5 M$ already present past years shortfalls
- The current budget available is 1.7 M$ with a 1.5 M$ usable base fund.
External funds
Following previous years "outsourcing" of funds approach, an note was sent to the STAR collaboration (Subject: RCF requirements & purchase) on 3/31/2008 12:18. The pricing offered was 4.2 $/GB i.e. 4.3 k$/TB of usable space. Based on the 2007 RCF requirement learning experience (pricing was based on vendor's total space rather than usable), the price was firmed, fixed and guaranteed as "not higher than 4.2 $/GB" by the facility director Micheal Ernst at the March 27th liaison meeting.
The institutions external fund profile for 2008 is as follows:
| STAR external funds | |||
| Institution | Paying account | TB requested | Price |
| UCLA | UCLA | 1 | 4300.8 |
| rice | rice | 1 | 4300.8 |
| LBNL | LBNL | 4 | 17203.2 |
| VECC | BNL | 1 | 4300.8 |
| UKY | UKY | 1 | 4300.8 |
| Totals | 8 | 34406.4 | |
Penn State university provided (late) funds for 1 TB worth.
*** WORK IN PROGRESS ***
Requirements
The requirements for FY08 are determined based on
The initial STAR requirements provided for the RHIC mid-term strategic plan can be found here
STAR resource requirements FY05-FY12
The initial raw data projected was 870 TB (+310 TB).
The RAW data volume taken by STAR in FY08 (shorter run) is given by the HPSS usage (RAW COS) as showed below:
A total of 165 TB was accumulated far below expected data projections by a factor of 2. The run was however declared as meeting (to exceeding) goals comparing to the STAR initial BUR.
Some notes:
- STAR made extensive use this year of fast triggers
- Based on those numbers, we assumed that
- The CPU requirements of 1532 kSI2k (+1071 kSI2k) would equally scale, hence a minimal requirement of +215 kSI2K should be accounted for
- A bigger pool of distributed storage would allow for more flexibility: it would allow for re-considering multiple (if not most of) the datasets to be placed on disk in Xrootd pool + it would allow (modulo expanding beyond the 1.2 replication baseline) to better load balance the resources.
- The distributed disk planing accounted for 365 TB of storage (1 pass production, small fraction of past results on disk). We targeted 800 TB of disk space (about twice the initial amount).

- 2008/08/14 13:44 - Answer from the RCF as per the above plan being approved (and commented it seemed easy)
- Two caveats: ETA cannot be provided until migration starts (one test example) to get a more accurate estimate
- While virtualmount point are swapped between one storage pool to another, there may be a fluke in access (will need infomring institutions / production disk will be handled by hard-dismount)
- 2008/08/14 13:42 - Sent an Email requesting infomration regarding disk manager and/or policies for PSU, UKY and RICE - Email sent to council rep and/or designated rep on August 14th 2008
- Answer from UKY 2008/08/14 13:56 >> Disk space manager=Renee Fatemi, policy = MIT policy
- Answer from PSU 2008/08/15 16:07 >> Policy is standard
