IOPS is commonly recognized as a standard measurement of performance whether to measure the Storage Array’s backend drives or the performance of the SAN. In its most basic terms IOPS are the number of operations issued per second, whether, read, writes or other and admins will typically use their Storage Array tools or applications such as Iometer to monitor IOPS. IOPS will vary on a number of factors that include a system’s balance of read and write operations, whether the traffic is sequential, random or mixed, the storage drivers the OS background operations or even the I/O Block size. Block size is usually determined by the application with different applications using different block sizes for various circumstances. So for example Oracle will typically use block sizes of 2 KB or 4 KB for online transaction processing and larger block sizes of 8 KB, 16 KB, or 32 K... (more)

'NetApp & Microsoft' vs 'EMC Cisco VMware'

2009 seems to have been the year of corporate marriages but whether they are marriages made in heaven is yet to be seen. The ongoing saga between Oracle and Sun and their child ZFS is already suffering from the clutches of the scorned mistress ECC, while the Dell/ Perot and HP/3Com matches are still in their honeymoon period. One partnership though which does look likely to stand the test of time and causes the biggest threat to all others is that of Cisco, EMC and their wonderkid Vmware. The discussion on how in my opinion these three will monopolise the future of ILM and cloud ... (more)

Has the SUN ORACLE Merger been SideKicked into Reality?

While personally, I believe the Sidekick disaster was just a stumbling block in the embracing of cloud computing for many organizations, today’s news that the newly formed alliance of SUN and Oracle was possibly to blame adds a whole new dimension to the issue. According to some reports the Sidekick service crash involved an Oracle RAC database and Solaris and Linux servers. Currently unlike EMC who were quick to retract the finger pointers, Oracle and Sun declined to respond to the accusations. To put a picture on the background of this scenario one needs to firstly look at the ... (more)
