Question
Scenario:
Your customer is a medium-sized law firm, with approximately 500 employees. They are beginning an infrastructure and backup upgrade project and have provided you with the infrastructure of their environment.
- Approximately 65 Windows hosts comprising of physical and virtual
servers
- 2 Exchange servers - 2 TB total storage
- 4 SQL Servers - 1 TB total storage
- Document management system - 4 TB total storage
- Disk Storage : CLARiiON CX3-20c iSCSI storage with 40 TB useable
storage
- Backup Target Devices : 5 x 5Tb Exagrid EX5000s and an ADIC Scalar
i500 with 3 x LTO3
- Current backup Software: HP Data Protector
- Backup regime Monday - Thursday; Friday - Full backup of all systems
is performed totaling approximately 20 TB.
- Monthly backup size is a duplicate of Friday but will also duplicate
to tape. The Data on the tape must be encrypted for legal reasons.
- Full Exchange Servers
- Incrementals for file systems and document management - Management
System - 4.5TB The customer regularly tests their DR procedures at a remote off-site facility utilizing a number of stand- alone devices to recover the data. The customer has asked you to specify a replacement storage and tape solution allowing for data growth and expansion of approximately 20% per annum. The storage solutions must be optimized for database and email applications as well as virtualized servers while enabling the customer to scale both capacity and performance linearly without incurring downtime or performance bottlenecks. Which HP tape solution would best meet the customer requirements?

Why each option
This question tests the ability to size and select the correct HP tape library for a 20 TB weekly full backup workload. The MSL4048 provides the necessary slot count and throughput for this environment.
The HP StoreEver MSL2024 offers only 24 slots, which may not provide sufficient capacity to hold multiple full backup generations alongside daily incrementals for a 20 TB weekly workload.
The HP StoreEver 1/8 G2 is an 8-slot autoloader intended for small office or entry-level workloads, far too small to support 20 TB weekly full backups requiring approximately 14 LTO-5 cartridges per run.
The HP StoreEver MSL4048 is a 48-slot tape library that supports up to two LTO drives, providing sufficient capacity to handle 20 TB full Friday backups plus incremental Monday-Thursday jobs and monthly retention copies. With LTO-5 media at approximately 1.5 TB native per cartridge, roughly 14 cartridges are needed per full backup, and the 48-slot magazine accommodates multiple backup generations simultaneously. This makes the MSL4048 the appropriate mid-range library choice for a 500-employee firm with 7 TB of active data spread across Exchange, SQL, and document management systems.
The HP EML71e is an enterprise-class modular library designed for large data centers, which would be significantly over-specified and cost-prohibitive for a 500-employee law firm.
