ESM (Enterprise System Management) support ratio

• Numbers of servers in Open (Win, Linux, Unix) covered by
ESM team (including BSM, CMDB, etc. – if implemented)
• MF AS/400 not included in server count – significant bias.
Best metric is “per CI monitored…”.
• Data about “not capable ESM teams – above 1000 servers
per FTE” not included
Per FTE # of Servers (all)

25 percentile 227
Median 412
75 percentile 485
Source: STKI
• About the same as last years data

DBA Ratios

• Number of open applications (all instances – dev, test, prod
counted as 1) supported by DBA :

Per FTE # of applications
25 percentile 17
Median 25
75 percentile 37

• The ratios are rather similar to last’s years result. This
means that storage staff has increased.

DBA FTE

Median 127 Servers 67 Servers
75 percentile 185 Servers 100 servers
Result the same as last year
Server is either physical or virtual
This includes SBCVDI (CitrixWTSJetro) support
For development environment’s ratios can grow up to 600 Servers per FTE
Organizations with 100% identical servers in branches can get ratios of 1:500 servers per FTE

Server Ratios –Unix Linux

Number of Unix (OS) and Linux servers per System member:
Per FTE Unix Linux Servers
25 percentile 31 servers
Median 45 Servers
75 percentile 100 Servers

Roughly same ratios as last year’s data
Virtualization is used much less in Unix then in WindowsLinux
Good metric for Unix is hard to find:
Per CPU (but there are machines with many virtual OS on each CPU)
Per OS (but there are sometimes huge machines with 1 OS)
Per physical server

NOC, Operators Ratio

• Number of production servers per NOC person:
Per FTE Servers (win, linux, unix)
25 percentile 73 servers
Median 108 Servers
75 percentile 196 Servers
• Huge variety of NOC responsibility:
• Look only at monitoring screens
• Batch operations (both production Control-M, FTP, and infra such as backup)
• Change management
• Service desk during night
• Physical room – electricity, cooling
• Mostly 7*24 withwithout Saturday
• In organizations with no NOC the Service Desk will have to look at the
monitoring screens
• MF AS/400 not included in count

Storage Ratios

• Number of Raw TB and Usable TB per Storage Staff
Member FTE (including backup and DRP of storage):

Per FTE RAW Storage Usable Storage
25 percentile 96T 49T
Median 250T 140T
75 percentile 429T 224T

• The ratios are rather similar to last’s years result. This
means that storage staff has increased.

Source: STKI

Usable/Raw storage ratio

• Net Storage in this research – usable for applications:
• After Raids
• After replication to DRP
• Without VTL’s
• The term “Usable storage” is tricky since with snapshots
application can see more storage then “Raw storage”

NETRAW Ratio

ERP staffing trends

Insourcing! Organizations prefer to “go it
alone” and only use outside help in new areas
Even then, they want to gradually train
their own people
Areas in which outside help is wanted:
 New modules (no knowledge)
 ERP Infrastructures (portals, BI, BPM) – Fusion, Netweaver
 Top experts knowledge – but only for a few hours


Size of ERP department depends on:

What “contributes” to Software maintenance:

• Not all “minor improvements” are the same:
• One company might put all improvement in “development budget”
while the other will put all “new development that is less than two
weeks”
• “Infra” is SW adjustment to infrastructure changes – Win7, Oracle 11G,
etc.
