What is the DASD limit (gigabytes) that can be allocated to an LPAR on a i5 570 Power6 that is running V5R4?
Is there a recommended storage level percentage for optimum performance / cost ? Obviously I realise there are lots of factors to take into consideration, such as projected growth, disk sizes / arms, I/O etc. But with all these catered for should I be looking at something around 75% or say 50%? 50% would seem [...]
Few days back we had an issue where DASD went up to 97% and even higher… Due to a user who have created a large file: Library . . . . . . : ABC Object Type Attribute Text XYZ *FILE ********** “Object with size has grown extremely High” We took a service dump and [...]
we’ve saved our production box, and restore it to a Disaster Recover box. the amount of DASD used is about 450Gig less than our prod box. everything seems to have restored (files, programs, logicals, ifs files, etc). restore sys and non-sys… can’t figure out what the extra 400gig is on our prod box…? anyone have [...]

Can anyone please elaborate the steps I need to perform inorder to reduce the ASP utilization of the system.Specifically for purging by using RCLSTG [...]
is the relation between DASD and ASP?
How does the installation of space on a Wintel server compare with the installation of DASD storage on a mainframe processor
We are considering use of one the OEM products that allows real-time tracking of DASD dataset usage and setting quotas on usage with optional prevention of allocations over budget. I have unsuccessfully tried to find anything information on what processor overhead these products carry. Example Products: DTS Software DLimit BMC Mainview SRM Reporting (used to [...]
How do you get the output from CA-View into a DASD dataset?
I am interested in understanding how much an iSeries costs (mid-range and enterprise level systems) and its associated hardware components such as DASD, memory, etc.. I have been browsing the internet, but I have not come across a site that clearly lists the price for a specific iSeries model or lists the price for all [...]
How much time should be allocated to install a 5095 with one 2780 PCI-X Ultra RAID Disk Controller and 12 – 4327 70.56GB 15k rpm Disk Drives?
Does anyone have experience with splitting a sysplex with isolated dasd and tape on each new plex? How do you move tape data between the new plexes efficiently? The only methods we are aware of are very awkward at best, e.g. copy tape to dasd, ftp dasd file to other plex, copy back to tape. [...]
Does anyone have an opinion on using one over the other? I am familiar with RGZPFM and it’s benefits but am not familiar with the PF option of reusing deleted records…I would think it would be better to reorganize the file rather than reusing deleted records becuase you could have a lot of deleted records [...]

Know how to physically install drives need to know the SST steps for intalling, formating and configuring the new drive array for RAID.
