Partek^® Flow^® requires the following for successful installation on a Linux-based system:

• Linux: Ubuntu^® 12.04, Redhat^® 6, CentOS^® 6, or newer
• Mac: OS X Yosemite 10.10 or newer
• 64-bit 2GHz quad-core processor
• 48GB of onboard memory
• 1TB of storage available for data
• /opt – 100GB of storage available for installation

• A broadband internet connection

Note that some analyses have higher requirements, e.g. to run the STAR aligner on a reference genome of size ~3 GB (such as human, mouse or rat), 16 cores are required. Input sample file size can also impact memory usage, which is particularly the case for TopHat alignments.

Increasing hardware resources (cores, RAM, disk space, and speed) will allow for faster processing of more samples.

Storage Recommendations

Proper storage planning is necessary to avoid future frustration and costly maintenance. Here are several DO's and DO NOT's:

DO:

• Plan for at least 3 to 5 times more storage than you think is necessary. Investing extra funds in storage and storage performance is always worth it.
• Keep all Flow data on a single partition that is expandable, such as RAID or LVM.
• Back up your data, especially the Partek Flow database.

DO NOT:

• Store data on 'removable' USB drives. Partek Flow will not be able to see these drives.
• Store data across multiple partitions or folder locations. This will increase the maintenance burden substantially.
• Use non-Linux file systems like NTFS.
