PowerProtect Appliance (DELL EMC) Types! Choos The Best Option!
DELL EMC PowerProtect Appliance has two types currently. We’ll review difference between two types at this post.
Optimizing Data Protection: Unleashing the Power of Database Backup Best Practices in Virtualization Platforms
Virtualization platforms such as VMware vSphere or Linux KVM supporting large scale of virtual machines now. Even, virtualization platforms can host monster virtual machines as database server. At this post, we’ll review database backup solutions in virtualization platforms about advantages and disadvantages.
Network Latency: Best Tools for Measuring
Enterprise businesses such as banking business using latency sensitive applications. Most of application delay issues are related to network infrastructure. Also most of application server are Linux servers. How can we measure network latency on Linux?
Fibre Channel Trunking (Aggregation): Better Performance, Higher Bandwidth (>1 Tb/s)
We are all knowing LACP on ethernet network but Fibre Channel and SAN network providing multipathing I/O by using logical and physical paths as single device on operating system and also using path selecting policies for using I/O paths optimized. But if server using 16Gb/s FC HBA, so there is no bandwidth aggregation. Server can generate bandwidth for each port up to maximum speed of port and also path selecting has performance impact of server when large paths are presented to server. Months before, I was thinking about FC port aggregation and did many searches but I didn’t find anything until now.
