For businesses that rely on storage, a Storage Area Network (SAN) is often their go-to solution. SANs offer a secure and reliable platform for storing both data and applications, but they also come with limits. Understanding these limits is essential if you want to ensure your business is running optimally. Let’s take a look at the different storage limits associated with SANs.
Maximum Size Of A Volume Group
A volume group (VG) is essentially a collection of physical disks all working together as one, larger disk. The maximum size of your VG depends on the type of hardware you use, but it can range from 16 terabytes up to 128 terabytes. If you need more than 128 terabytes of storage, then you will need to create two or more VGs and use them in conjunction with each other.
Maximum Number Of Logical Units
Logical units (LUNs) are virtual disks made up of space taken from one or more VGs. Depending on your hardware, the maximum number of LUNs you can create ranges from 256 to 2^32-1, which equates to 4 billion LUNs! This means that even if you have a large amount of data and applications stored in your SAN solution, there should still be plenty of room for expansion when necessary.
In Summary
- A Storage Area Network (SAN) offers a secure and reliable platform for businesses that rely on storage.
- The maximum size of a volume group (VG) varies depending on the type of hardware used, but it can range from 16 to 128 terabytes.
- Depending on the hardware, the maximum number of logical units (LUNs) a SAN can have is between 256 and 4 billion.
