1. MHz/GHz only measure microprocessor internal clock speed, not application performance. Many factors affect application performance.
2. When referring to hard disk drive capacity, GB equals one billion bytes. Total user accessible capacity may vary depending on operating
environments.
3. Onboard mirroring, which is equivalent to RAID 10, is supported in BladeCenter HS20 when a SCSI Storage Expansion Unit is installed with two
matching SCSI hot-swap HDDs.
4. A maximum of 28 processors are supported when 14 HS20s are installed in the BladeCenter.
5. The maximum of 56GB of memory is based on 4GB in each of 14 HS20s.
6. Maximum storage of 1.588TB is based on seven HS20s with two 40GB IDE HDDs in each and a SCSI Storage Expansion Unit attached to each
HS20 containing two 73.4GB Ultra160 SCSI hot-swap HDDs.

File and Print numbers are Novell Netware-based with all others based on Microsoft Windows NT®. Other Network Operating System (NOS) results
could vary.

Step 1: Determine which application (row) most closely represents the customer’s environment.
Step 2: Move from left to right along the row (chosen in Step 1) noting which columns contain numbers that are equal to or greater than the
maximum customer’s planned number of users.
Step 3: Move up the columns (chosen in Step 2) to the top row to determine which IBM xSeries or Netfinity servers should be considered as
possible solutions.
Step 4: Evaluate other features such as storage, memory capacity, high availability components, number of available expansion slots, etc., which
are unique to each server, in order to determine which is the most appropriate to recommend.
For your reference, configuration information corresponding to the number of users is also provided.
